  1. 1. RADIOLOGY UPDATE DEPARTMENT OF RADIOLOGY VOL. 16, No. 2 JULY 2004 Radiology Update is published semiannually to inform colleagues and friends of new developments in diagnostic radiology and nuclear medicine. Editor: Monzer Abu-Yousef, MD Associate Editor: Joan Maley, MD Managing Editor: Nichole Jenkins Copy Editor: Glena Clarke Photographers: Connie Sherman and Jim Olson MDCTApplications forAbdominal Imaging (CTA) by Kousei Ishigami, MD, Visiting Assistant Professor, Department of Radiology (continued on page 4) Multidetector-row computed tomogra- phy (MDCT) has dra- matically changed ab- dominal CT applica- tions. The potential of MDCT lies in its strik- ing improvement of spatial (thinner slice thickness) and tempo- ral (faster scan time) resolution. Thin slice images improve z-axis (cranio-caudal direction) resolution, which enables acquisition of high qual- ity three dimensional (3D) or multiplanar refor- mation images. In the MDCT era, it is not too much to say that CT is a modality that not only demonstrates the transverse (axial) plane, but also demonstrates multiple planes. CT angiography (CTA): To obtain optimal ar- terial phase CTAimages, a higher IV contrast in- jection rate (5 cc/sec) is desirable, requiring at least a 20 G IV catheter. Bolus tracking (real- time monitoring for contrast arrival while ob- taining a density curve of the target organ [e.g. abdominal aorta]) is useful to ensure appro- priate scan timing. Theoretically, injection du- ration (contrast volume/injection rate) should be longer than the scan time for the arterial phase of CTA. The volume of contrast can be reduced if the scan time is shortened, which is another advantage of MDCT. In addition, a saline chase (e.g. 50 ml of saline flush follow- ing 100 ml of contrast injection instead of us- ing 150 ml of IV contrast) may also be useful in administering IV contrast more efficiently, which may potentially reduce the total vol- ume of IV contrast used. CTA provides an accurate and reliable roadmap for vascular anatomy of the abdo- men to evaluate the arterial and venous sys- tems.

  2. 2. JULY 2004 RADIOLOGY UPDATE 2 Notes from the Chair Update on Research in the Department of Radiology Laurie L. Fajardo, MD Professor & Head, Department of Radiology This month the Department celebrated the opening of a new research laboratory, the Iowa Comprehensive Lung Imaging Center (I-CLIC). The laboratory, directed by Eric Hoffman, Ph.D., is equipped with a state-of-the-art 16-slice CT scanner and a micro-CT system. The event was commemorated with a 2-day scientific forum featur- ing researchers from across the United States and Ger- many. Dr. Hoffman has been a member of the Depart- ment of Radiology since 1992. Over the last 18 months, the Department has experi- enced considerable growth in its research enterprise, ow- ing to the success of several faculty in the department and to the recruitment of new researchers. Three new MR Scientists were recruited to work within 2 broad areas: (1) Neuro-imaging sciences (both neurological and psychia- try-based research) – Jinhu Xiong, PhD and Vincent Magnotta, PhD and (2) Cardiovascular imaging – Daniel Thedens, PhD. In addition, a new CT Scientist Researcher has recently joined the faculty – Shiying Zhao, PhD. Com- Grants FY1999 FY2000 FY2001 FY2002 FY2003 FY2004-Projected $2,374,484 $3,813,039 $4,280,382 $3,625,621 $5,881,133 $7,314,200 mensurate with these new recruits, the department has entered into a strategic research alliance with Siemens Medical to leverage and advance several mutual research interests. Further support for the department’s research enter- prise will be enabled by the acquisition of several dedi- cated research imaging systems. This year the installation of two MR research systems (a 1.5 Tesla and a 3 Tesla) into the MR Imaging Clinic is planned. The clinic is cur- rently undergoing extensive remodeling and expansion. In addition, two 16-slice research CT scanners will support research in computed tomography. The first 16-slice CT scanner has been installed in the Iowa Comprehensive Lung Imaging Center. The second CT scanner will reside in the department and will be dedicated to supporting clini- cal CT research. Renovations for the new PET Center are well underway; the center will include two PET-CT systems, as well as a PET system dedicated to research. Aside from the “human” imaging systems for research, the department has been enormously successful in gar- neringsupportforseveralanimalimagingsystems,including two micro CT systems, a bioluminescence CT system, a micro PET system, and several other nuclear medicine instruments (gamma camera, 3 headed SPECT system and a PET system for larger animals). These instruments form the basis for a complete small animal imaging facil- ity now being planned by the College of Medicine. The current design locates the imaging systems in a contigu- ous 3,000 sq. ft. area, within the Medical Education Re- search Facility (MERF) building. The close proximity to the animal support facilities, the I-CLIC and the other COM imaging facilities makes it an ideal support center for the Holden Comprehensive Cancer Center and researchers through out the university. The Department of Radiology has had a steady increase in successfully funded research grants over the past few years. Last year, the Department ranked 13th among de- partments of radiology nationwide in NIH grant funding.

  4. 4. JULY 2004 RADIOLOGY UPDATE 4 vascular anatomy in the abdomen is nearly 100%. CTA has been utilized in attempting to evaluate various vascular pathologies. In the near future, CTA will replace many conventional diagnostic angiographic exams. Diagnostic value of CTAis comparable to contrast enhanced 3D mag- netic resonance angiography (MRA). However, it should be stressed that CTA is faster and cheaper than MRA, and better at evaluating small vessels. In addition, MRA can be operator dependent and requires patient coopera- tion (e.g. holding breath). With the advent of MDCT, diagnostic radiologists should become familiar with a workstation, since the image data have significantly increased, and hard copy reading is be- coming impractical. In abdominal imaging, the act of cre- ating 3D images should be paired with interpretation. Al- though axial images may be sufficient for diagnosis in most cases, it is best to make the most of high quality multiplanar reformation capabilities (as well as source images), which will ultimately increase the confidence level of interpreta- tion. The abdominal imaging applications of MDCT are not only used for CTA. For example, CT urography (CTU) is a valuable and simple modality for the workup of a patient with hematuria, producing clearer images of renal tumor, stone, and lesions outside of the GU system. CTU can be a single and complete modality of choice, and the total cost and radiation dose of CTU should be compared to those of other diagnostic modalities, since multiple studies are oc- casionally needed for diagnosis. VenousphaseofCTA (MDCTportography,TargetedMIP Image) of a patient with portal venous occlusion demonstrates gastrojejunal varices (arrow). CTAis also useful to evaluate portal venous system and portosystemic shunt less invasively. CTU (Targeted MIPimage) shows normal collecting systems and ureters. Bladder stones are present. MDCT Applications, continued from page 1 Sectional Update Pulmonary Radiology Division by Brad H. Thompson, MD, Associate Professor, Director of Diagnostic Imaging & Chief of Cardiovascular & Pulmonary Radiology The Chest Imaging section that has traditionally been composed of 2.5 faculty members has a new faculty mem- ber from Japan. Dr. Koji Takahashi, who currently holds a faculty position as Associate Professor from Asahikawa Medical College,Asahikawa Japan, joined The University of Iowa Radiology Department last summer as a visiting professor. His primary interests are in chest imaging with special concentrations on mediastinal imaging and lung can- cer staging. Additionally, Dr. Takahashi’s expertise also extends to vascular and interventional radiology, particu- larly related to cases involving the cardiovascular system. Koji will be an active member of the section until 2005. The section is very pleased to have Koji here, and we cer- tainly appreciate his valuable contributions to the section and to the department. The section continues to be involved in several funded research projects. Several faculty members continue to participate with faculty from Pediatric Cardiology in the “Muscatine Study” which is a federally funded longitudinal study looking at long term risk factors for cardiovascular disease. The section provides expertise and interpretations (continued on next page)
  5. 5. RADIOLOGY UPDATE JULY 2004 5 Research Iowa-Comprehensive Lung Imaging Center by Eric A. Hoffman, P.h.D., Professor of Radiology, Physiology and Biomedical Engineering of helical coronary calcium scans that are performed on all study subjects. As a result of this study, members of the study group have published two manuscripts this year, both within the journal, Radiology, which compare helical and ultrafast CT in coronary calcium detection, as well as as- sess the influence of anthropomorphic variations patients have on quantitative coronary calcium measurements. Members of the chest section are also currently involved in an American College of Radiology Imaging Network (ACRIN) study evaluating low dose CT screening for lung cancer. The NIH sponsored National Lung Screening Trial (NLST) seeks to compare the sensitivity of helical CT to digital radiographs in pulmonary nodule / cancer detection. To date, 1155 subjects have been enrolled in the NLST project at Iowa, which represents the 3rd highest enroll- ment accrual in the country. The UIHC NLST team was the recipient of three awards this year for attaining highest monthly accrual numbers nationwide. Dr. Brian Mullan is co-primary investigator on the UIHC NLST study, with participation from additional faculty members from the sec- tion, and employs two full-time and three part-time research associates.Anew research project has recently commenced in collaboration with the Division of Pulmonary Medicine, which will focus on the efficacy of implanted endobron- chial one-way valves as a potential treatment for pulmo- nary bullous disease. This project, called the VENT Study, will be instrumental in clearing the way for this unique de- vice to receive final FDA approval. Human subjects are currently being recruited to participate in the VENT project here at Iowa. On the clinical side, the section is currently re-evaluating IV contrast doses for helical CT. Preliminary data shows that the previous doses for routine chest CT exams can be effectively reduced by 30-40% with no deleterious effects on the quality of enhancement of the cardiovascular sys- tem. Such a reduction in nonionic contrast usage would result in a cost savings of 15-20% annually. Additionally, the section has recently adopted changes in their helical CT screening protocol for pulmonary thromboembolic dis- ease. By implementing 2mm thick sections (rather than 3mm), the section anticipates an improvement in sensitivity for PE detection by 20%. The division is also currently investigating incorporating leg exams as part of the PE pro- tocol to diagnose deep venous thrombosis. Chest CT has received wide clinical acceptance as the new imaging stan- dard for the diagnosis of acute and chronic pulmonary embolism at UIHC. Dr. Hoffman arrived at The University of Iowa’s Department of Radiology in 1992.As a cardio-pulmonary physiologist, he has studied the basic principles of heart and lung physiology through the novel use of imaging technologies.At the Univer- sity of Iowa, Dr. Hoffman, along with his colleague, Dr. Geoffrey McLennan of the Pulmonary Division in the Department of Medicine, have pulled together a group of collaborators from the Departments of Radiology, Medi- cine (Pulmonary Division), Anesthesiology, Surgery, Pa- thology, Speech Pathology, Otolaryngology, Biomedical En- gineering, Computer and Electrical Engineering, Computer Sciences along with collaborators from the University of Washington,TheJohnsHopkinsUniversity,theMayoClinic, Purdue University, Marquette University, the University of Texas – Houston, and the University of Auckland to form what has become known as the Iowa-Comprehensive Lung Imaging Center or I-Clic. The combined funding of Dr. Hoffman and other key members of I-Clic exceed 30 mil- lion dollars over a 5-year period. The group, with Hoffman as PI, attracted one of the first Biomedical Engineering Partnership grants awarded by the NIH, and one of the few that came out of the National Heart, Lung and Blood Institute. The goal was to develop a set of scanning and image analysis methods to allow for the comprehensive assessment of the lung by use of multidetector row CT (MDCT) in order to establish an atlas / model of the nor- mal male and female human lung for 3 decades of age range with the notion that, through an understanding of “nor- mal,” early pathology can be detected, quantitated and fol- lowed. The I-Clic is currently in partnership with Siemens Medical who has agreed to keep a newly renovated CT imaging research suite instrumented with state-of-the-art CT equipment for the next 6 years. The facility currently houses a Sensation 16 with a rotation speed of 0.375 (continued on page 6)

This system will be up- graded to a 64-slice scanner within the next six to eight weeks. The research scanning facility also houses a Skyscan 1076 Micro CT scanner which provides in vivo mouse imaging capabilities with an isotropic voxel dimen- sion of between 9 and 35 microns. This scanner was pro- vided to the center through collaboration withAventis. The pharmaceutical company’s interest is in using in vivo and ex vivo imaging of the mouse lung as a means of drug discovery. The facility also includes both an animal surgi- cal suite and a human preparation area, and video conferencing equipment is set up throughout the facility to allow for up to 10 sites to simultaneously conference to- gether during an experiment in such a way that the remote sites are able to observe any area within the facility, along with images and physiological signals. Iowa-Comprehensive, continued from page 5 In addition to basic research into lung physiology and pathophysiology, Dr. Hoffman serves as the PI of the im- age archive and analysis centers for the NIH sponsored National Emphysema Treatment Trial (NETT), the Severe Asthma Research Program (SARP), and the recently funded pulmonary arm of the Multi-ethnic Study of Ath- erosclerosis (MESA) study (MESA-Lung). Drs. McLennan and Mullan (Pulmonary Medicine and Radiology respec- tively) serve as the PI and co-PI of the Iowa component of the National Lung Screening Trial, and Drs. McLennan and Hoffman are part of the Lung Image Database Con- sortium (LIDC), a five center consortium funded by the National Cancer Institute to establish a public image data- base of lung nodules with associated ground truth which can be used by developers of computer aided detection The 2nd Annual Alumni and Friends Program of the Department of Radiol- ogy at the University of Iowa Hospi- tals and Clinics was held on April 17, 2004. Awide spectrum of former resi- dents and faculty attended the meet- ing. Some were from as close as Iowa City (Bob Brown, Bill Erkonen and Charles Lu), with others from as far away as California (Calvin Yang). The day began with a seminar for graduates and faculty of the 1980’s. This allowed a lively interchange of comments on today’s practice of radi- ologyandvariousmethodologiestocope with concerns. In the afternoon, the senior residents gave their research presentations to an appreciative audience of alumni, faculty and peers. After a considerable, toughdeliberation,theEvaluation Committee chose Matt Berst’s paper, “Effect of Prior Know- ledge of Chronological Age on Variability in Bone Age Deter- ner of the Outstanding Research Pre- sentation Award. Hiroshi Honda, a 1986-89 alumnus of UI Radiology, now Chair at Kyushu University in Japan, was Visiting Pro- fessor for the program. He presented a great lecture to the group on new de- velopments in abdominal imaging at Kyushu University. The evening event included a recep- tion and banquet for attendees – resi- dents, faculty and spouses and friends. Sponsors for the event included Eastman Kodak, Amersham Health (now a division of General Electric) and Cassling Diagnostic Imaging.
