CT explores size, growth of ground-glass nodules

Two 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.

VC obviates need for colonoscopy even in symptomatic patients

Even 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.

Study to compare 320-row CT perfusion against SPECT

Following 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.

320-row perfusion CT shows promise for pancreatic tumors

Perfusion 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.

New VC CAD algorithm reveals submucosal colon cancers

A 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.

CTA motion model aims to improve cardiac function analysis

Dutch 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.

DSCT edges out 64-slice CT in coronary artery imaging

Coronary 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.

VC CAD aids experts in detecting intermediate polyps

Computer-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.
