  16. 16. “We decided to implement ASiR on 100% of our examsand achieved excellent results. As such, ASiR has becomea key component in our campaign for low dose CT.The community response from both our patients andphysicians was greater than we ever expected, andUW is now viewed as the go-to place for low dose CT”William P. Shuman, M.D.University of Washington Medical Center“With the Discovery CT750 HD, we have been able tosignificantly reduce radiation dose while, at the sametime, improving image quality. Our patients arebenefiting from the dose reduction in every exam weperform, all without compromising diagnostic quality.With this dramatic dose reduction our practice hasgrown our referral base, and patients are asking to bescanned on the Discovery CT750 HD.”David A. Dowe, M.D.Atlantic Medical Imaging“With the Discovery CT750 HD we have been able toreduce drastically the dose in coronary CTA, whileimproving image quality. We routinely scan patients atless than 1 mSv and still achieve high diagnostic quality.”Jean-Nicolas Dacher, M.D., Ph.D.Rouen University Hospital16 GE Healthcare Discovery CT750 HD
  17. 17. ASiR may reduce dose byup to 50%1by allowing theuse of lower mA protocols — and with high definitionimage quality across allanatomies — the DiscoveryCT750 HD can reach anypart of the body, any agepatient, and any applicationthat demands the leadingedge of CT clarity.1. In clinical practice, the use of ASiR may reduce CT patient dosedepending on the clinical task, patient size, anatomical locationand clinical practice. A consultation with a radiologist and aphysicist should be made to determine the appropriate dose toobtain diagnostic image quality for the particular clinical task.ASiR dose reduction was measured on a standard 20cm waterphantom. The test involved maintaining constant pixel standarddeviation as the mA was reduced at 120 kVp. GE Healthcare Discovery CT750 HD 17
  18. 18. A better path forwardIncremental reductions in dose cango a long way toward supportingimproved care, but the higheststandard can only be achievedthrough breakthrough innovationin image reconstruction.Leading the way with image reconstructionTypically, lowering dose has increased noise and imageartifacts, creating an unfortunate trade-off betweenhigher image quality and lower dose. In order to over-come this obstacle, GE developed an industry exclusivehigh definition approach to image reconstruction — Adaptive Statistical Iterative Reconstruction (ASiR).Low dose kidney stone protocol at 83 mAs18  GE Healthcare Discovery CT750 HD
  19. 19. ASiR provides exceptional image quality by improving lowcontrast detectability (LCD) and suppressing noise withoutdegrading anatomical integrity. It overcomes the limitationsof the conventional CT reconstruction approach knownas filtered back projection and arrives at an optimal imageusing an advanced iterative computation. As a result, theDiscovery CT750 HD is capable of significant dose reductionwith no loss of diagnostic image quality. Since its introductionin 2008, ASiR has earned positive mention from cliniciansin peer-reviewed journals, in dozens of abstracts, and atmultiple conferences. Millions of patients’ exams make ASiRthe proven choice for image reconstruction. GE Healthcare Discovery CT750 HD 19

In clinical practice, the use of ASiR may reduce CT patient dose depending on theclinical task, patient size, anatomical location and clinical practice. A consultationwith a radiologist and a physicist should be made to determine the appropriate doseto obtain diagnostic image quality for the particular clinical task.4. Dose reduction was measured on a standard 20cm water phantom comparing aSnapShot Pulse prospective gated axial acquisition at 120kV/300mA and 50% ASiR toa cardiac helical acquisition 120kV/500mA without ASiR both with a 224mm scancoverage.5. In clinical practice, the use of SnapShot Pulse may reduce cardiac CT patient dosedepending on the clinical task and patient heart rate. A consultation with a radiologistshould be made to determine the appropriate acquisition mode and scan settings toobtain diagnostic image quality for the particular clinical task.24  GE Healthcare Discovery CT750 HD

  27. 27. Gemstone Spectral Imaging is a revolutionary featureexclusive to the Discovery CT750 HD. Today, it is expandingthe information available for clinical diagnosis andworkflow in the following key areas: characterization ofsmall lesions, beam hardening reduction, kidney stonecharacterization, optimization of contrast and virtualnon-contrast like imaging. Tomorrow, its broad applicationsand unprecedented level of detail have the potential tocompletely re-define diagnostic imaging. GE Healthcare Discovery CT750 HD 27
  28. 28. GemstoneSpectral ImagingGemstone SpectralImaging (GSI) is a uniquedual energy technique thatuses rapid kV switchingand Gemstone Detectortechnology to acquire andgenerate material densitydata. This data can beused to separate materialsand derive monochromaticspectral images usinga projection-spacereconstruction algorithm.Virtual noncontrast-like imagingGemstone Spectral Imaging can subtract iodine fromimages to generate a virtual noncontrast-like image.Note the kidney stone is obscured in the IV contrastimage, but visualized in the water density image.70 keV SpectralMD WaterMaterial SeparationGSI provides information about the chemical composi-tion of body materials. This capability enables the userto easily separate calcium, iodine and water to aid inthe characterization of pathology.28  GE Healthcare Discovery CT750 HD
  29. 29. Quantitative Lesion Characterizationat 50cm FOVSpectral Imaging’s potential to enhance lesion charac-terization is seen here with the two lesions displayedon the images. Utilizing GSI and viewing the images atlower spectral energy, the lesion is more conspicuous,and the differentiation of the non-enhancing cystand enhancing lesion is well depicted on the spectralcurves, normalized to the liver parenchyma.70 keV Spectral 70 keV Spectral colorSpectral Hounsfield unit curve Normalized Spectral Hounsfield unit curve GE Healthcare Discovery CT750 HD 29
  30. 30. “Traditionally, CT provided an excellent depiction of thepulmonary vessels, thrombi and emboli. However, itcould not give us information on the severity ofpulmonary embolism obstruction or perfusion deficitdefects. With the GSI-generated iodine maps, I canclearly see the severity of perfusion deficit. GSI is avery effective technique that eliminates the need foradditional scans to gather functional information onlung perfusion.”Valentin Sinitsyn, M.D., Ph.D.Moscow Federal Center of Medicine“About 40% of our routine spine exams involve metalinstrumentation. Reducing artifact for these exams isan important benefit that GSI provides. Spectral CTgenerates virtually pristine images in these mostchallenging circumstances where traditional techniquesoften fail.”Lawrence N. Tanenbaum, MD, FACRMount Sinai School of Medicine“With Gemstone Spectral Imaging we can more easilyobtain high quality images on the femoral arteries inpatients with metallic hip prostheses. This capability isparticularly important when planning a transcatheteraortic valve implantation (TAVI).”Jean-Nicolas Dacher, M.D., Ph.D.Rouen University Hospital30  GE Healthcare Discovery CT750 HD

  32. 32. Enhancing image quality with monochromatic spectral imageExclusive to the Discovery CT750 HD, the spectral image is created as thoughit comes from a single energy (keV) source. Individual spectral images canbe derived from 101 user-selectable energy levels. This approach enablesimage contrast optimization, accurate CT numbers and up to a 50% reductionin common beam hardening artifacts — features that together aid in a fast,confident diagnosis.Utilizing lower energy spectral images allows for better contrast differen-tiation, thereby accentuating subtle contrast differences.In the study below, due to the patient’s impaired renal function only 60ccof contrast was utilized. With GSI’s capability to review different levels ofmonochromatic energy levels for better iodine conspicuity, the endoleakwas visualized.VR images VR images demonstratingthrombusConventional CT 93 keV Spectral image 93 keV VR Spectral imageCurved view demonstratingendoleak visualizationBeam hardening reductionReducing visually obstructive beam hardening artifacts will reveal impor-tant underlying anatomical information for a complete diagnosis.32  GE Healthcare Discovery CT750 HD
  33. 33. How it worksCentral to spectral image acquisition is the Gemstonedetector’s ability to differentiate between two differentenergy levels from view to view (as illustrated by theblue and green data sets below). Both high and lowenergy data sets are acquired simultaneously to improveimage registration for material separation throughoutthe full 50cm field of view.Using known attenuation curves, the material specificdifference in attenuation enables an easy classificationof the elementary chemical composition of the scannedtissue. This creates the ability to generate materialdensity images.Spectral images are derived from the material densityimages and depict how the object would look if theX-ray source produced only photons at a single energy.QuickerDiagnosisequalsReducedHospitalCostPainful episodes of renal-relatedconditions result in more than onemillion patient visits to emergencydepartments annually.1Reducingthe time spent on imaging,additional testing, and waiting forresults has the potential todecrease both length of stay andoverall costs to the hospital. This iscritical, as hospitals are paid a fixedamount per admission regardlessof the number of services provided.Using GE’s Discovery CT750 HDwith Gemstone Spectral Imaging(GSI), a single contrast-enhancedCT may provide information toevaluate the presence or absenceof a renal lesion. With the sameexam data, GSI can create a “virtualnon-contrast like image” that canprovide information to assess forkidney stones. GSI also has theability to help characterize renalstones without a urinalysis — meaning treatment can startearlier, minimizing in-patient staytime. GSI can also help physicianscharacterize lesions, reducingthe need for additional testing inpatients with symptoms whoseCT results indicate a renal mass.80 kVp raw data140 kVp raw data1,968 views reconstruction+1.

  40. 40. VolumeShuttle —twice the coverage with less doseVolumeShuttle helps make the most challengingneuro CT perfusion and angiographic studies possible.It doubles the acquisition coverage to 80mm, with lessdose. As a result, practitioners can perform studiessuch as 4D CTA and CT perfusion in a single scan andwith a single contrast injection. For Neuro imaging itensures ample coverage to perform “whole territoryperfusion” (from the basal ganglia to the top of thelateral ventricles).Extending coverage forfunctional assessmentThe Discovery CT750 HD allows for extended coveragefor both 4D CT Angiography (CTA) and perfusion studieswith two innovative features: VolumeShuttle*andVolume Helical Shuttle combined with CT Perfusion 4D,which provides volumetric functional analysis using anew Smart Map that creates noise reduced maps whilepreserving functional detail. They both extend coverageand overcome today’s challenge of coverage limitedby detector width.Perfusion coverage1up to 140mm4D CTA coverage up to 312.5mm40  GE Healthcare Discovery CT750 HD

Up to 120mm for brain perfusion.Volume Helical Shuttle —further extending the rangeThe Discovery CT750 HD introduces an innovativeapproach to further extend coverage for studies suchas 4D CTA and large internal organ physiologicalassessments. Volume Helical Shuttle is a continuousbi-directional scan mode that extends z-coverage andimproves temporal sampling. GE’s unique DynamicPitch reconstruction method utilizes acquired scan dataduring table acceleration and deceleration rather thanonly during constant table speed. The result is morethan 300mm of high-resolution volume coverage for4D CTA studies.Volume Helical Shuttle may enable anatomical assess-ment that surpasses the coverage of today’s widestdetectors and enables you to set the coverage to exactlythe range you need. For example you can perform a4D CTA study to characterize the inflow and outflow ofcontrast in the arterial and venous system over a lengthof 312.5mm, equivalent to a 500-slice image. In addition,Volume Helical Shuttle allows you to perform perfusion1studies for the brain and body organs.three-seriesscantime-savingresultsOn average, someone in the UnitedStates has a stroke every 40 seconds.2Discovery CT750 HD’s ability toacquire whole brain coverageperfusion in addition to the otherstroke workup exams provides theinformation physicians need tomake a diagnosis. Hospitals receivea fixed payment for admittedpatients, so reducing the amount ofresources used translates directlyto cost saving for the hospital.With GE’s Discovery CT750 HD, asingle three-series scan can providethe results of a non-contrast CT, a4D dynamic CT angiography, and12 cm of whole brain perfusioncoverage at once. Discovery CT750HD’s Volume Helical Shuttle (VHS)with 12 cm of full coverage allowsfor whole brain imaging, which canpotentially eliminate the need forfollow-up MR and reduce the costof a patient’s hospital stay.312.

  44. 44. The latest advance inCT image reconstructiontechnologyVeo is the world’s first model-based iterative recon-struction product. This breakthrough is changingthe way physicians use CT imaging. It may deliver acombination of high-quality images and low dosethat was previously unthinkable.GE Healthcare has solved this challenge in partnershipwith leading healthcare partners and hardwaremanufacturers, combining sophisticated algorithmsand advanced computing power. As a result, a CTreconstruction technique that was once only theoreticalhas now been put into practice.So radiologists and clinicians can now operateunder a new set of rules. Lower pixel noise standarddeviation and higher resolution may be achievedwithin a single image. Veo may help clinicians achieveconfident diagnosis with lower dose, opening upnew possibilities for challenging cases and sensitivepatients.1“Veo may reduce dose but also increase image quality:In oncology studies, we can increase the conspicuityof the tumor for tissue characterization — In vascularstudies, it is possible to differentiate stenosis fromocclusion and reduce the blooming effect that resultfrom the presence of a stent or calcified plaque. Thereare instances where a higher quality study is moreimportant, and Veo enables us to increase spatial andcontrast resolution to visualize very small lesions.”Dr. Jean Louis SablayrollesCentre Cardiologique du Nord, Saint Denis, France1. In clinical practice, the use of Veo may reduce CT patient dosedepending on the clinical task, patient size, anatomical locationand clinical practice. A consultation with a radiologist and aphysicist should be made to determine the appropriate dose toobtain diagnostic image quality for the particular clinical task.44  GE Healthcare Discovery CT750 HD
  45. 45. New levels ofimage qualityVeo provides a new benchmarkfor CT image quality. Its powerfulmodeling techniques may result inbetter images, delivering previouslyunattainable levels of combinedpixel noise standard deviationreduction, resolution gain,improved contrast, and artifactsuppression.1In traditional approaches, higherspatial resolution is accompaniedby higher image noise. But Veochallenges this common trade-off.Veo may improve resolution andmay reduce pixel noise standarddeviation.1FBPVeoImages courtesy of Dr. Sablayrolles,CCN, France1. In clinical practice, the actual level of low signal artifact, LCD and resolutionimprovement may vary. Consult with a radiologist and a physicist. GE Healthcare Discovery CT750 HD 45
  46. 46. Imaging under 1mSvThe benefits of dose reduction are significant, especiallyfor the most radiosensitive patients — including pediatriccases and young women. Veo may also provide theopportunity to dramatically reduce cumulative dose inpatients who require regular follow-up exams.1“Veo allowed us to scan a chest CT at 0.06 mSv withreadable images where pathology could be analyzed.With Veo, we can conduct lower dose CT scans inchildren, and this is particularly important in groupsthat require continued follow-up, such as those withcystic fibrosis or lymphoma.”Professor Johan de Mey, M.D.Chair of Radiology Department,University Hospital, BrusselsDLP of 5.02, 0.02 mSv, obtained by EUR-162662 EN, using a pediatric head factor of 0.004*DLP46  GE Healthcare Discovery CT750 HD
  47. 47. Veo is the next step in GE’s commitment to lower-doseCT. Our ASiR technology, introduced with the launch ofthe Discovery CT750 HD, offers fast reconstructions andmay allow for low-dose imaging without compromise — an ideal approach for routine, robust imaging. By push-ing the possibilities even further, Veo represents addedcapability for the most sensitive cases. By changingthe rules, these potential dose-reduction capabilitiesopen up exciting new possibilities in CT.Veo establishes new rules in the relationship betweenimage quality and dose reduction. Veo can give theclinicians the diagnostic information they need andmay allow for it to be done at a previously unthinkablelow dose.1So at an equivalent dose, Veo may deliverdramatically better aspects of image quality.The rules have changed. But the goal hasn’t.Radiologists and clinicians have another powerful newtool to deliver more informed, confident diagnoses. Andabove all else, Veo can help achieve what has alwaysbeen the ultimate goal — the best patient care available.DLP 3.16, 0.05 mSv, obtained by EUR-16262 EN, using a chest factor of 0.017*DLP1. In clinical practice, the use of Veo may reduce CT patient dose depending on the clinical task, patient size, anatomical location andclinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnosticimage quality for the particular clinical task.
