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 kVp. At temporalregistrations speeds of up to timesfaster than the nearest competitor,GSI is the first quantitative dual energyon the market.

Grayscale quantitative MD iodine image Colored quantitative MD iodine imageIn the arterial phase images, you can visualize an early contrastuptake, especially on iodine and low keV images. FBPIn 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 aphysician should be made to determine the appropriate dose toobtain diagnostic image quality for the particular clinical task.

Veo image, 0. Shuman, M. 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 CT HD. Dowe, M. We routinely scan patients atless than 1 mSv and still achieve high diagnostic quality. 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. 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.

Since its introductionin , ASiR has earned positive mention from cliniciansin peer-reviewed journals, in dozens of abstracts, and atmultiple conferences. At The improvement in spatialresolution is real and impacts my practice ona daily basis. Intelligent system design helps tomanage high and unstable heartrates in prospective andretrospective modes. In the second independent study,2using a combination of SnapShotimaging, reduced tube voltage andASiR, we have observed in patients an average dose of 1.

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. 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.

Low-risk chest pain patientsin the emergency department: Negativechannel cardiac CT angiography mayreduce length of stay and hospital charges. AJR ; S5 : A1. A traditional cardiac diagnosticpathway can take between 12 and36 hours, utilizing a significantamount of hospital time, personnel,and resources. A recent study has reported that adiagnostic work up of a single setof enzymes and an ECG along witha cardiac CT angiography CCTA takes an average of only 5 hours torule out coronary artery disease,compared to an average of 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.

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. This capability enables the userto easily separate calcium, iodine and water to aid inthe characterization of pathology.

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. 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.

Reducing artifact for these exams isan important benefit that GSI provides. Spectral CTgenerates virtually pristine images in these mostchallenging circumstances where traditional techniquesoften fail. This capability isparticularly important when planning a transcatheteraortic valve implantation TAVI. Gemstone Spectral Imagingis delivering real diagnosticresults today.

Tomorrowit has the potential to beused as a routine scanacquisition mode, taking thepossibilities even further. Individual spectral images canbe derived from user-selectable energy levels.

Utilizing lower energy spectral images allows for better contrast differen-tiation, thereby accentuating subtle contrast differences.

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. This iscritical, as hospitals are paid a fixedamount per admission regardlessof the number of services provided. GSI can also help physicianscharacterize lesions, reducingthe need for additional testing inpatients with symptoms whoseCT results indicate a renal mass.

Brown J. Diagnostic and treatmentpatterns for renal colic in US EmergencyDepartments. International Urology andNephrology ; Combined, they set a new standardin diagnostic imaging; enabling greater degreesof insight, broader applications and newbenchmarks of care. With technologies and featuresthat set new benchmarks for image clarity, high-definitionCT opens the door to new non-invasive diagnosticcapabilities and innovative techniques for challengingconditions. A dramatic reduction inelectronic noise— Low noise, for outstand-ing image quality in highand low signal areas ofthe anatomyImproved spatialresolution across entire fieldof view— 2.

And with Veo, clinicians can achievepreviously unheard of image quality at doses lowerthan ever before—a bold step into the future of high-definition CT imaging. In clinical practice, the use of ASiR and Veo may reduce CTpatient dose depending on the clinical task, patient size,anatomical location and clinical practice. A consultation with aradiologist and a physicist should be made to determine theappropriate dose to obtain diagnostic image quality for theparticular clinical task.
