CTA motion model aims to improve cardiac function analysis

By Eric Barnes

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

By Eric Barnes

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.

Chest x-ray CAD fails to boost observer performance

By Erik L. Ridley

CHICAGO - Computer-aided detection (CAD) software may not produce significant improvement in detecting suspicious lesions on chest radiographs, but it's not necessarily the technology's fault, according to research presented Wednesday at the 2009 RSNA meeting in Chicago.

Coronary CTA edges CMR in a tight race

By Eric Barnes

CHICAGO - In a head-to-head comparison of two closely watched modalities, low-dose dual-source coronary CT angiography (CTA) outperformed cardiac MR (CMR) in sensitivity, specificity, and negative predictive value. But 1.5-tesla CMR countered with better specificity and positive predictive value.

Scientific poster digital format offers potential to transform medium

By Cynthia E. Keen

CHICAGO - Displaying scientific posters in digital format at this year's RSNA meeting allows authors not only to convey facts, graphs, and photos, but also to incorporate some interactive functionality. Onsite digital displays offer huge potential to educate readers in ways that even the best developed paper poster cannot.

In patients with stable chest pain, CT is more often diagnostic than exercise ECG

By Reuters Health

NEW YORK (Reuters Health), Nov 2 - Unlike exercise electrocardiography (XECG), CT angiography is "nearly always" feasible and diagnostic in patients with stable chest complaints, researchers say in the October issue of the journal Heart.
