Diagnostic balloon occlusion in normal coronary arteries is safe
By Reuters Health
NEW YORK (Reuters Health), May 18 - Diagnostic balloon occlusion is safe in normal coronary arteries, researchers say. They studied outcomes of the procedure in 133 patients with 141 entirely normal coronary arteries and 183 patients with 285 partially normal arteries (at least one stenotic lesion).

3T MRA protocol has value but falls short in abdominal vasculature
By Wayne Forrest
A time-resolved 3-tesla MR angiography (MRA) technique that uses less contrast dose than conventional high-resolution MRI has some advantages in the abdominal aorta, but its lower signal-to-noise ratio means it probably won't supplant conventional MRA, according to a study in the May Academic Radiology.

Less DNA damage seen after high-pitch coronary CTA
By Eric Barnes
High-pitch dual-source CT angiography (CTA) scans produce significantly less radiation-related DNA damage than comparable low-pitch dual-source CTA scans -- and, importantly, the DNA results correspond to both measured and derived biological radiation doses, say researchers from Erlangen, Germany.

Cardiac cath delivers high radiation doses to operators
By Eric Barnes
The rapid development of new cardiac stents and other medical devices is opening up a world of possibilities for interventional procedures in the cath lab -- but it's also exposing equipment operators to ever-higher radiation doses.

Heart rate key to image quality in low-dose coronary CTA
By Eric Barnes
Heart rate control is an important factor for success in prospectively gated coronary CT angiography (CTA). But once patients are beta-blocked, the success rate is high and the doses are uniformly low, according to a new study by Swiss researchers.

CT better than MRI for ruling out coronary disease
By Reuters Health
NEW YORK (Reuters Health), Feb 2 - When a noninvasive test for ruling out coronary artery disease is appropriate, CT-based angiography is more sensitive and specific than MRI-based angiography, a new meta-analysis shows.

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.

CT calcium detection helps rule out obstructive coronary disease
By Reuters Health
NEW YORK (Reuters Health), Dec 15 - Non-enhanced CT for calcium detection is a reliable way to exclude obstructive coronary artery disease in patients with chest pain, researchers report in the December issue of the American Journal of Cardiology.

Contrast dose halved in coronary CTA
By Eric Barnes
CHICAGO - Contrast doses for CT angiography (CTA) are too high, but they can be lowered substantially with the right equipment and careful attention to technique, according to researchers from Charité University Medical School in Berlin.

Trial can't prove PCI to be noninferior to CABG for diabetics with complex CAD
By Reuters Health
NEW YORK (Reuters Health), Dec 1 - A large study of revascularization strategies in diabetics with multivessel coronary artery disease, which set out to show that angioplasty is not inferior to bypass surgery for these patients, could not prove its hypothesis.
