Eric Barnes[email protected]Clinical NewsCT explores size, growth of ground-glass nodulesTwo studies recently published online in Radiology yield important new information about CT-detected part-solid lung nodules. Mass measurements of ground-glass nodules are the most accurate, say Dutch researchers, but a Korean group found that most part-solid nodules disappear over time -- and do so in predictable ways.February 23, 2010Clinical NewsVC obviates need for colonoscopy even in symptomatic patientsEven among individuals with symptoms suggesting a higher risk of colorectal polyps and cancer, virtual colonoscopy screening is enough to prevent most of them from having to undergo invasive colonoscopy, according to a recent study from the Netherlands.February 23, 2010Clinical NewsCoronary CTA and MR MPI have complementary rolesCoronary CT angiography (CTA) and MR myocardial perfusion imaging (MPI) work best as a team for evaluating chest pain patients with suspected coronary artery disease, according to a new study published online in Radiology.February 21, 2010Clinical NewsStudy to compare 320-row CT perfusion against SPECTFollowing up on the CORE 64 study that tested the value of coronary CT angiography vis-à-vis angiography, researchers have launched a new international trial to compare 320-detector-row CT perfusion to SPECT myocardial perfusion imaging for detecting early coronary artery disease.February 9, 2010Clinical News320-row perfusion CT shows promise for pancreatic tumorsPerfusion CT with a 320-detector-row scanner offers improved resolution of pancreatic tumors due to its ability to image the entire organ without slice overlap, according to researchers from Berlin and Toronto.February 4, 2010Clinical NewsNew VC CAD algorithm reveals submucosal colon cancersA new computer-aided detection (CAD) algorithm goes beyond flat-polyp detection to find submucosally invading colorectal cancers with virtual colonoscopy. Researchers say the software offers an important alternative to traditional CAD feature classification that could improve the sensitivity of all VC studies.February 3, 2010Clinical NewsPerfusion CT handily distinguishes malignant neck nodesIn a new study from Poland, perfusion CT showed impressive accuracy for distinguishing benign from malignant lymph nodes in a study of squamous cell cancer patients with suspected metastases.January 24, 2010Clinical NewsCTA motion model aims to improve cardiac function analysisDutch researchers used an automated coronary artery motion model to analyze cardiac function from electrocardiogram-gated coronary CT angiography (CTA) data. The method promises to improve cardiac function analysis and reconstruction interval selection, and even provide new information on coronary artery motion at different heart rates.January 10, 2010Clinical NewsDSCT edges out 64-slice CT in coronary artery imagingCoronary CT angiography performed on dual-source CT (DSCT) confers a slight advantage in image quality with slightly fewer nondiagnostic vessel segments compared to 64-detector-row CT. Calcification remains a challenge with both types of scanners, but it's slightly less problematic with dual-source systems, say researchers from the University of Rome.January 7, 2010Clinical NewsVC CAD aids experts in detecting intermediate polypsComputer-aided detection (CAD) can improve the performance of experienced radiologists in detecting intermediate-sized (6- to 9-mm) polyps, but it doesn't help find larger lesions, said researchers from Italy in results presented at the RSNA meeting earlier this month.December 27, 2009Previous PagePage 48 of 59Next PageTop StoriesRadiology EducationNordic survey pinpoints motivators and obstacles in researchWhat factors inspire radiologists to engage in research?
