High-pitch CT cuts dose for patients with low heart rates

By Eric Barnes

Austrian radiologists have found a way to cut the radiation dose of coronary CT angiography studies to as low as 1 mSv by using a high-pitch scanning protocol on a 128-slice scanner for patients with low heart rates.

32-channel 3.0-T MRI and 64-slice CT detect CAD equally well

By Reuters Health

NEW YORK (Reuters Health) - In a prospective comparative study, 32-channel 3.0-tesla MRI and 64-slice CT angiography similarly identified significant coronary stenosis and similarly predicted revascularization in patients with suspected or known coronary artery disease (CAD).

Reentrant tachycardia recurs more often after cryoablation vs RF ablation

By Reuters Health

NEW YORK (Reuters Health) - In the short term, cryoablation and radiofrequency (RF) ablation were equally effective for atrioventricular nodal reentrant tachycardia in a German study -- but six months later, recurrence was higher with cryoablation.

MR angiography accurate for diagnosing peripheral artery disease

By Reuters Health

NEW YORK (Reuters Health), Sep 7 - Contrast-enhanced magnetic resonance angiography reliably identifies arterial stenosis/occlusion in adults with symptoms of peripheral artery disease and accurately stages the extent of disease, results of a meta-analysis show.

Coronary CT angiography valuable in asymptomatic patients, safer than ever

By Reuters Health

NEW YORK (Reuters Health), May 28 - In patients with elevated cardiac risk but without cardiac symptoms, coronary CT angiography can reliably predict cardiac events and assess cardiovascular risk, German researchers reported online April 30 in the American Journal of Cardiology.
