  2. 2. Macclesfield Cheshire SK10 3BL NEW BOOKS IN THE LIBRARY None this month WEBSITES [Ctrl + click for links] From Biomed Central 29 January 2008 BioMed Central bolsters radiology image collection BioMed Central has partnered with the American Roentgen Ray Society to add more journals and images to GoldMiner(tm), the ARRS radiology search engine. BioMed Central, the open access publisher of peer-reviewed biomedical research has contributed over 170 journals, adding over 4,200 images to the GoldMiner(tm) collection. The collection now numbers over 170,000 images and over 225 journals. "GoldMiner(tm) speeds your search for radiology images by quickly matching search criteria with peer-reviewed content available on the Web," said Charles E. Kahn, Jr., MD, a creator of GoldMiner(tm). "By limiting results to images from respected, peer-reviewed journals, you won't spend a lot of time sifting through thousands of unrelated images or images from unknown sources. You can save more time by filtering by imaging modality, patient age and gender," said Dr. Kahn. "BioMed Central is very happy to be partnering with the ARRS to expand their radiology image search tool with the indexing of thousands of openly licensed images from our journals," said Matthew Cockerill, publisher of BioMed Central. "We are always keen to encourage creative use of the open access articles which we publish and GoldMiner(tm) is a great example of this," he said. From Bloglines 22/1/08 National PACS steering group disbanded A shake-up in national governance arrangements for PACS across England has been signalled by Connecting for Health (CfH). From Health Management Specialist Library Report into the effects of CT scanning asymptomatic people The Committee on Medical Effects of Radiation in the Environment [COMARE] has published its 12th Report: The impact of personally initiated X-ray computed tomography scanning for the health assessment of asymptomatic individuals including recommendations into the regulation of such tests and consideration of whether or not they are effective in a public health context. COMARE press release From Aunt Minnie 9/1/08 Multislice CT detects coronary disease in men and women NEW YORK (Reuters Health) - Multislice computed tomography (MSCT) coronary angiography appears highly effective in diagnosing obstructive coronary artery disease in both men and women, Dutch researchers report in the January issue of Heart. To investigate, Dr. Jereon Bax, of Leiden University Medical Center, and colleagues studied 50 men and 50 women with known and suspected coronary artery disease who underwent 64-slice MSCT.
  3. 3. 21/1/08 Trauma radiologists overhaul abdominal CT contrast protocols Radiologists routinely administer both an oral barium suspension and IV contrast for evaluating suspected appendicitis, diverticulitis, and small-bowel obstruction (SBO). Would studies work as well without oral contrast? And what about oral iodine? Can it replace barium in abdominal applications other than virtual colonoscopy? Two research groups recently explored these issues. 21/1/08 Ultrasound quality strongly affects ovarian cancer management NEW YORK (Reuters Health) - Improving the quality of pre-operative ultrasound can reduce the number of unnecessary staging procedures performed to confirm ovarian cancer and can also shorten the hospital stay, according to a report in the January 21st online issue of The Lancet Oncology. 23/1/08 Groups advocate less radiation for kids Thirteen radiology-related organizations are urging healthcare practitioners to significantly reduce the amount of radiation administered to children during imaging scans. 25/1/08 Cochrane Review studies mammo discomfort In a review of studies conducted to evaluate ways to reduce mammography exam discomfort, women's imaging vendor Hologic's MammoPad breast cushions were found to reduce pain, according to the Cochrane Collaboration of Oxford, U.K. 29/1/08 DMIST: Women under 50 with dense breasts benefit from FFDM Full-field digital mammography (FFDM) performs significantly better than film-screen in one particular subgroup of women, according to researchers of the Digital Mammographic Imaging Screening Trial (DMIST). They examined the DMIST data for 10 subgroups of women, and found that women younger than 50 with dense breasts benefited the most from FFDM. 31/1/08 False positives a concern with FDG-PET/CT for head, neck tumors FDG-PET/CT is worthwhile for assessing patients with occult head and neck primary tumors, but false positives remain a shortcoming of the hybrid technology, according to a British study. The results show that FDG-PET/CT cannot replace examination under anesthesia and biopsies for assessing occult head and neck primary tumors. 4/2/08 Dark-field x-ray measures scatter radiation for better image quality A new technique for producing images could offer a way to create higher-quality images using conventional digital radiography equipment, according to Swiss researchers. The technique, called dark-field x-ray, is based on radiation scattered from a target rather than the traditional method of using radiation absorbed by the target. The researchers discussed their implementation of dark-field imaging in a paper published in Nature Materials. 5/2/08 Ultrasound shows promise as a screening tool for wrist pain More than 2.2 million people in the U.S. turn up at their doctor's office with complaints of wrist pain, but ordering up costly MRI and MR arthrography exams -- or radiation-laden CT arthrography -- is not always feasible. Orthopedic specialists from Tucson's University of Arizona have proposed ultrasound-based exams as a screening tool for wrist ligaments. 12/2/08 The use of computer-aided detection (CAD) software for digital radiography (DR) images is a relatively new application, but the combination could prove useful if DR is to develop a role in lung screening. One possible fly in the ointment, however, is the impact of various DR postprocessing techniques on CAD functionality. DR data can be manipulated, massaged, and processed in various ways, any one of which could affect CAD's ability to detect suspicious lung nodules.
  4. 4. Chinese researchers address this issue in an article we're featuring this week in our Digital X-Ray Community. The investigators used a commercially available CAD application to analyze DR images processed with three different types of image postprocessing techniques. They found that CAD's performance varied widely based on the type of image processing used, with statistically significant variations in nodule detection and false-positive rates.

The research offers a rebuttal to last year's New England Journal of Medicine study that found that CAD actually reduced the accuracy of breast screening centers that used it. Click here to read the rest of the article. 14/2/08 A new study published this week has reignited the debate over the use of computer- aided detection (CAD) software for mammography screening. The new research finds that CAD has a beneficial role in breast screening, contradicting the results of last year's controversial study in the New England Journal of Medicine. In the new study, U.S. researchers analyzed their experience with CAD in more than 230,000 patients over four years, according to an article in our Women's Imaging Digital Community by staff writer Kate Madden Yee. The methodology specifically addressed a number of the perceived shortcomings in the earlier NEJM study that CAD proponents believe reduced the accuracy for sites using CAD. The new study found that sites using CAD turned in results that were superior compared to those of a single reader, and comparable to double reading by two radiologists. What's more, CAD's recall rate didn't exceed that of double reading. The question is, what impact will the study have on recent efforts by insurance payors to restrict CAD reimbursement? So far, CAD advocates have successfully beaten back most of the proposed cuts -- this week's study should give them another weapon in their arsenal.

Technologies like CT and MRI have developed indispensable roles in determining the course of treatment during the "golden hour," when at-risk brain tissue can be saved by the accurate administration of therapy. But imaging's role in stroke diagnosis and treatment is still evolving, and that's the subject of a new series on stroke imaging we're featuring this week in our CT Digital Community by staff writer Eric Barnes. In part I of the series, we examine the role of imaging in identifying brain tissue that can be salvaged through early and effective treatment. Part of the problem is that, despite recent advancements, medical imaging is still limited to simplistic representations of brain physiology. Even some of the terms imaging specialists use to describe at-risk brain tissue -- such as the term "penumbra" -- aren't completely accurate. Learn more about the current state of the art in stroke imaging by clicking here. We'll be running part II of this series in our next CT Insider newsletter, so make sure you're signed up to get it.

Walsgrave Hospital University Hospitals of Coventry and Warwickshire NHS Trust Patients benefit from and are reassured by advance information on procedures that they are to undergo. Ward nurses should have adequate knowledge of radiological investigations to ensure proper patient preparation and good interdepartmental communication to avoid delays and cancellations. This study was conducted to assess the ward nurses' knowledge of the process of computed tomography (CT) scanning. One hundred and twenty qualified nurses were asked to complete a questionnaire regarding CT scanning. The findings revealed a suboptimal level of awareness about the process. This is probably due to lack of formal teaching for nurses on the wards in regards the different radiological procedures and patient preparation. There is a strong case for better educational talks on rapidly changing radiological techniques for ward staff to ensure high-quality patient care.

Study Design: Four normal subjects underwent 3T MRI scanning after the administration of gadodiamide intravenous (IV) contrast. MRI region of interest signal intensity was used to determine the diffusion of gadodiamide into the perilymphatic fluid spaces over time. Seven subjects with unilateral Meniere's disease underwent 3T MRI 4 hours after administration of gadodiamide IV contrast agent. Results: All four normal subjects demonstrated perilymphatic enhancement by 4 hours postinjection. Loss of definition of the membranous cochlea was noted in five of the seven subjects with Meniere's disease. Precise definition of the scala media could not be achieved with this imaging protocol. Conclusion: Delayed contrast imaging of the inner ear with 3T MRI revealed in vivo changes of the membranous labyrinth consistent with unilateral Meniere's disease. NEUROLOGY Web link to this journal 70(7):512-520, February 12, 2008 MRI patterns of atrophy associated with progression to AD in amnestic mild cognitive impairment SYMBOL Whitwell, J L.; Shiung, M M.; Przybelski, S A.; Weigand, S D.; Knopman, D S.; Boeve, B F. et al Abstract
  10. 10. Objective: To compare the patterns of gray matter loss in subjects with amnestic mild cognitive impairment (aMCI) who progress to Alzheimer disease (AD) within a fixed clinical follow-up time vs those who remain stable. Methods: Twenty-one subjects with aMCI were identified from the Mayo Clinic Alzheimer's research program who remained clinically stable for their entire observed clinical course (aMCI- S), where the minimum required follow-up time from MRI to last follow-up assessment was 3 years. These subjects were age- and gender-matched to 42 aMCI subjects who progressed to AD within 18 months of the MRI (aMCI-P). Each subject was then age- and gender-matched to a control subject. Voxel-based morphometry (VBM) was used to assess patterns of gray matter atrophy in the aMCI-P and aMCI-S groups compared to the control group, and compared to each other. Results: The aMCI-P group showed bilateral loss affecting the medial and inferior temporal lobe, temporoparietal association neocortex, and frontal lobes, compared to controls. The aMCI-S group showed no regions of gray matter loss when compared to controls. When the aMCI-P and aMCI-S groups were compared directly, the aMCI-P group showed greater loss in the medial and inferior temporal lobes, the temporoparietal neocortex, posterior cingulate, precuneus, anterior cingulate, and frontal lobes than the aMCI-S group. Conclusions: The regions of loss observed in subjects with amnestic mild cognitive impairment (aMCI) who progressed to Alzheimer disease (AD) within 18 months of the MRI are typical of subjects with AD. The lack of gray matter loss in subjects with aMCI who remained clinically stable for their entire observed clinical course is consistent with the notion that patterns of atrophy on MRI at baseline map well onto the subsequent clinical course. SPINE Web link for this journal 33(4):E109-E115, February 15, 2008 Surgical Results in Hidden Lumbar Spinal Stenosis Detected by Axial Loaded Computed Tomography and Magnetic Resonance Imaging: An Outcome Study Willen, Jan ; Wessberg, Per J. ; Danielsson, Barbro Abstract Study Design. An outcome study of patients with neurogenic claudication and/or sciatica with hidden stenosis, detected only by axial loading of the lumbar spine (ACE) but not at the traditional unloaded examination (psoas relaxed position) during computed tomography (CT) myelography or magnetic resonance imaging (MRI), followed up after surgery. Objective. To estimate the clinical effect of decompression with or without fusion in patients with hidden stenosis in the lumbar spine. Summary of Background Data. A number of patients with neurogenic claudicatio with or without sciatica do not have corresponding imaging abnormalities. Axial loaded CT and MRI have disclosed hidden stenosis in certain cases. The surgical effect in patients with hidden stenosis has never been described. Methods and Materials. Axial loading of the lumbar spine during CT and MRI was performed in 250 patients with neurogenic claudication and sciatica. All fulfilled the inclusion criteria for ACE, i.e., suspected but not verified spinal stenosis in 1 to 3 levels. In 125 patients (50%), a significant narrowing of the spinal canal occurred. Out of these 125 patients, 101 had a clear stenosis besides the stenosis only detected at ACE. In 24 patients, a hidden stenosis was detected in 1 to 3 levels only at the ACE. These patients were observed for 1 to 6 years after decompression with or without fusion regarding subjective improvement of leg and back pains, walking capacity, satisfaction, and health related quality of life.
  11. 11. Results. At follow-up, 76% of the patients had leg pain less than 25/100 on a VAS scale and 62% had back pain less than 25/100. Ninety-six percent were improved or much improved regarding leg and back pains The ability to walk increased significantly after surgery. Walking capacity to more than 500 m increased from 4% to 87%. Twenty-two patients were subjectively satisfied with the surgical results. The ODI score, the SF-36 and the EQ-5D score corresponded well to the above mentioned improvements at follow-up. Conclusion. According to this study, the results of surgery in hidden lumbar stenosis only detected by axial compression in extension during CT or MRI, are convincing and comparable with the results of surgical treatment for stenoses diagnosed by unloaded examinations. STROKE Web link to this journal Publish Ahead of Print, published online before print, 31 January 2008 Antidepressant Treatment and Worsening White Matter on Serial Cranial Magnetic Resonance Imaging in the Elderly: The Cardiovascular Health Study Steffens, David C. ; Chung, Hyoju ; Krishnan, K Ranga R. ; Longstreth, W T. Jr et al Abstract Background and Purpose-: In some studies, late life depression is associated with white matter lesions on MRI. The effect of different classes of antidepressants on progression of white matter lesions is unknown. Selective serotonergic reuptake inhibitors (SSRIs) may decrease platelet aggregation. We hypothesized that Cardiovascular Health Study participants taking SSRIs would less often have worsening white matter on serial MRI than participants not on antidepressants. Methods-: Among 1826 participants who were not using an antidepressant at initial MRI scan, we examined the association of worsening in white matter grade from initial to follow-up MRI scans, 5 years apart on average, and antidepressant use between the scans. Logistic regression models were used, controlling for a variety of potential confounding variables. Results-: Use of any antidepressant during the period of study was associated with worsening white matter. In a multivariable model, risk was slightly increased, not reduced, with use of serotonergic agents (OR 1.36, 95% CI 0.87 to 2.12) and was significantly increased with the use of tricyclic antidepressants (OR 1.77, 95% CI 1.07 to 2.94). Conclusions-: The association between worsening white matter and use of tricyclic antidepressants was an unexpected finding that may relate to indications for use other than depression or to side effects such as hypotension.

It remains unclear, however, if there is a volume threshold of LA that is needed before either the signs of dementia and/or a specific pattern of neuropsychological impairment become manifest. Roman et al has suggested that 25% of white matter may need to be involved before white matter alterations influence the clinical signs associated with dementia. The purpose of this study is to ascertain the threshold of MRI-LA as measured with a visual rating scale needed to induce specific patterns of
  12. 12. neuropsychological impairment associated with dementia. Methods-: One hundred fifteen patients with dementia received a comprehensive neuropsychological examination and the severity of MRI-LA was measured using a 40-point LA scale. Results-: Patients were categorized into low (mean LA=4.21+/-2.92; 3.22%-17.82%), moderate (mean LA=12.58+/-2.54; 25.01%-37.80%), and severe (mean LA=22.36+/-4.04; 45.80%-66.00%) LA groups. Patients in the mild LA group obtained markedly lower scores on tests of episodic memory compared with working memory, a neuropsychological profile often associated with Alzheimer disease. Patients with moderate LA displayed equal impairment on neuropsychological tests. Patients in the severe LA group obtained significantly lower scores on tests of working memory as compared with episodic memory. Conclusions-: These data provide evidence that a threshold of moderate MRI-LA as measured with a visual rating scale is associated with greater and/or equal impairment on tests of working memory versus episodic memory and provides a benchmark to assess the effect of MRI-LA on the clinical presentation of dementia. Publish Ahead of Print, published online before print, 7 February 2008 Gray Matter Atrophy in Patients With Ischemic Stroke With Cognitive Impairment. Stebbins, Glenn T.; Nyenhuis, David L. ;Wang, Changsheng ; Cox, Jennifer L. ; Freels, Sally et al Abstract Background and Purpose-: Patients with ischemic stroke are at risk for developing vascular cognitive impairment ranging from mild impairments to dementia. MRI findings of infarction, white matter hyperintensities, and global cerebral atrophy have been implicated in the development of vascular cognitive impairment. The present study investigated regional gray matter volume differences between patients with ischemic stroke with no cognitive impairment and those with impairment in at least one domain of cognitive function. Methods-: Ninety-one patients with ischemic stroke participated. Detailed neuropsychological testing was used to characterize cognitive functioning in 7 domains: orientation, attention, working memory, language, visuospatial ability, psychomotor speed, and memory. High-resolution T1- weighted 3-dimensional fast-spoiled gradient recalled structural MRIs were processed using optimized voxel-based morphometry techniques while controlling for lesions. Whole brain voxelwise regional differences in gray matter volume were assessed between patients with stroke with no impaired cognitive domains and patients with stroke with at least one impaired cognitive domain. Logistic regression models were used to assess the contribution of demographic variables, stroke-related variables, and voxel-based morphometry results to classification of cognitive impairment group membership. Results-: Fifty-one patients had no impairments in any cognitive domain and 40 patients were impaired in at least one cognitive domain. Logistic regression identified significant contributions to cognitive impairment groups for demographic variables, stroke-related variables, and cognitive domain performance. Voxel-based morphology results demonstrated significant gray matter volume reductions in patients with stroke with one or more cognitive domain impairment compared with patients with stroke without cognitive impairment that was seen mostly in the thalamus with smaller reductions found in the cingulate gyrus and frontal, temporal, parietal, and occipital lobes. These reductions were present after controlling for group differences in age, education, stroke volume, and laterality of stroke. The addition of voxel-based morphometry- derived thalamic volume significantly improved a logistic regression model predicting cognitive impairment group membership when added to demographic variables, stroke-related variables, and cognitive domain performance. Conclusions-: These results suggest a central role for the thalamus and lesser roles for other cortical regions in the development of cognitive impairment after ischemic stroke. Indeed,
  13. 13. consideration of thalamic volumes adds significant information to the classification of cognitive impaired versus nonimpaired groups beyond information provided by demographic, stroke- related, and cognitive performance measures.
