CT approaches IVUS in plaque detection
By Eric Barnes
Monday, 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.

Extent of perfusion defects predicts PE outcomes
By Eric Barnes
Monday, 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.

CT equivalent to MRI in evaluating ventricular size, function
By Eric Barnes
Monday, 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.

Liver CT shows high accuracy in steatosis assessment
By Eric Barnes
Monday, 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.

High-pitch, free-breathing DSCT improves pulmonary embolism assessment
By Eric Barnes
Monday, 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.

Monochromatic images erase beam-hardening artifacts
By Eric Barnes
Monday, 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.

Perfusion quantified in normal, infarcted myocardium
By Eric Barnes
Monday, 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.

Newer readers need contrast for acute appendix
By Eric Barnes
Monday, 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.

Military radiologists report on experiences in Afghanistan
By Eric Barnes
Sunday, November 27 | 2:00 p.m.-3:30 p.m. | RC124 | Room N229Navy physicians Dr. Ron Boucher and Dr. Steve Ferrara recently returned from deployment to the Kandahar Air Base in southern Afghanistan armed with gripping stories and images of wartime radiology. The presentation will show the efforts of U.S. and coalition medical teams operating in the country as they care for coalition forces, as well as Afghan military personnel and many civilians.

HR-pQCT helpful in osteogenesis imperfecta patients at risk of severe fracture
By Eric Barnes
Sunday, November 27 | 11:45 a.m.-11:55 a.m. | SSA14-07 | Room E451BHigh-resolution peripheral quantitative CT (HR-pQCT) is compared to dual-energy x-ray absorptiometry (DEXA) in patients with osteogenesis imperfecta in this presentation by Austrian researchers. They found that CT does a better job than conventional DEXA bone mineral density scans of characterizing bone structure and the risk of fracture.

CT perfusion inadequate to detect basilar artery occlusion
By Eric Barnes
Sunday, November 27 | 11:25 a.m.-11:35 a.m. | SSA16-05 | Room N226CT perfusion imaging of the brain is often used in acute stroke centers to aid in diagnosing and characterizing acute stroke. But it doesn't work as well in the brainstem: A new study has found that CT perfusion alone is inadequate to detect basilar artery occlusion.

Automated kV cuts abdomen dose the easy way
By Eric Barnes
Sunday, November 27 | 11:05 a.m.-11:15 a.m. | SSA08-03 | Room E450BA study from Massachusetts General Hospital has shown that automated kV selection is feasible, providing the benefits of lower kV imaging without complicated protocols.
