Replacing xenon with stable krypton gas might make the procedure easier for patients to complete, according to a new study.November 9, 2011CTDual-energy measurements aid electronic cleansing in VCTuesday, November 29 | 10:30 a.m.-10:40 a.m. | SSG13-01 | Room S403AA study of dual-energy index values at the boundary between colonic mucosa and air found significant enough differences between components of the bowel lumen to develop new virtual colonoscopy computer-aided detection schemes that will be more accurate than current-generation systems that rely on CT attenuation values.November 9, 2011CTCT approaches IVUS in plaque detectionMonday, November 28 | 3:30 p.m.-3:40 p.m. | SSE03-04 | Room S502ABA study comparing CT to intravascular ultrasound (IVUS) for plaque detection found that CT isn't quite ready to take on ultrasound -- but it's not far off, the authors concluded.November 9, 2011CTExtent of perfusion defects predicts PE outcomesMonday, November 28 | 3:30 p.m.-3:40 p.m. | SSE05-04 | Room S404CDQuantifying perfusion defects at dual-energy CT helps identify pulmonary embolism (PE) patients at risk of adverse outcomes and should be part of their risk assessment, say investigators from the University of Munich.November 9, 2011CTCT equivalent to MRI in evaluating ventricular size, functionMonday, November 28 | 3:10 p.m.-3:20 p.m. | SSE03-02 | Room S502ABVentricular size and function are important for diagnosing and managing patients with several conditions. Fortunately, dual-source CT has caught up to the reference standard, MRI, for the task, say researchers from the Medical University of South Carolina.November 9, 2011CTLiver CT shows high accuracy in steatosis assessmentMonday, November 28 | 3:00 p.m.-3:10 p.m. | SSE08-01 | Room E450BUnenhanced CT is highly specific for detecting and characterizing steatosis or fatty liver, according to researchers from the University of Wisconsin, in cooperation with Dr. Seong Ho Park and colleagues from Asan Medical Center.November 9, 2011CTHigh-pitch, free-breathing DSCT improves pulmonary embolism assessmentMonday, November 28 | 11:20 a.m.-11:30 a.m. | MSVE21-10 | Room E353AHigh-pitch CT pulmonary angiography with dual-source CT (DSCT) in freely breathing patients consistently provides diagnostic image quality, suppresses artifacts, and has the potential to further reduce contrast material usage, according to new research from Goethe University.November 9, 2011CTMonochromatic images erase beam-hardening artifactsMonday, November 28 | 11:10 a.m.-11:20 a.m. | SSC16-05 | Room S403BSynthesized monochromatic imaging with fast kV switching at 40 keV to 70 keV may boost the magnitude and uniformity of aortic enhancement for a wide range of body sizes, say researchers at Duke University.November 9, 2011CTPerfusion quantified in normal, infarcted myocardiumMonday, November 28 | 10:50 a.m.-11:00 a.m. | SSC01-03 | Room S502ABA new CT study from the Medical University of South Carolina found significant differences in myocardial perfusion parameters for ischemic and infarcted myocardium compared with normal myocardium.November 9, 2011CTNewer readers need contrast for acute appendixMonday, November 28 | 9:00 a.m.-9:10 a.m. | MSVE21-02 | Room E353AHow important is contrast for diagnosing suspected appendicitis? Researchers from New York University's Langone Medical Center and department of radiology conducted a novel study that examined appendiceal visualization rates in the same patient with and without oral and IV contrast.November 9, 2011Previous PagePage 95 of 258Next PageTop StoriesMRICheck for middle neck involvement for nasopharyngeal cancer prognosis"Our study establishes [MNI] as an independent prognostic determinant in N1 and N2 nasopharyngeal carcinoma," researchers wrote.Molecular ImagingPET links brain receptor to emotional numbing in PTSDWomens ImagingCEM, DBT show promise for preoperative breast cancer stagingMRIMRI illumines how the brain maintains 'representation' of phantom limbsDigital X-Ray3D DEXA reveals lower bone density in diabetes patients
