CT perfusion quantifies neoangiogenesis in HCC tumors
By Eric Barnes
Tuesday, November 29 | 11:10 a.m.-11:20 a.m. | SSG05-05 | Room E353CResearchers in Italy believe that CT perfusion can noninvasively quantify tumor blood supply in hepatocellular carcinoma (HCC) that relates to tumor neoangiogenesis, a process that is essential for tumor growth. The knowledge will help doctors better assess the disease and strategize treatment options, they said.

Myocardial perfusion stress CT moves to clinical use
By Eric Barnes
Tuesday, November 29 | 10:50 a.m.-11:00 a.m. | SSG02-03 | Room S503ABCardiac CT is ready for the comprehensive assessment of coronary artery disease in routine clinical use, say researchers from the Medical University of South Carolina. In the group's initial experience applying myocardial perfusion CT to a clinical population with acute chest pain, the technique detected myocardial perfusion defects just as well as the reference standards, MRI and SPECT.

Krypton replaces xenon for patient-friendly ventilation lung scan
By Eric Barnes
Tuesday, November 29 | 10:40 a.m.-10:50 a.m. | SSG03-02 | Room S504ABVentilation lung scans with high-resolution CT can be used to examine lung morphology and function in patients with chronic obstructive pulmonary disease. Replacing xenon with stable krypton gas might make the procedure easier for patients to complete, according to a new study.

Dual-energy measurements aid electronic cleansing in VC
By Eric Barnes
Tuesday, 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.

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.
