Coronary CTA study aims for lowest dose

A study from Switzerland concludes that low-dose prospectively gated coronary CT angiography (CTA) is both feasible and promising, but not without wrinkles. Relying on prospectively triggered gating and some of the lowest radiation doses yet achieved for prospectively gated coronary CTA, the team reported that 95% of all coronary segments achieved diagnostic image quality, but image quality was very dependent on heart rate.

Sublingual nitroglycerin improves coronary CTA

Nitroglycerin significantly improves the results of coronary CT angiography (CTA) by dilating the coronary arteries before scanning, researchers in Belgium have reported. Their study found that vessel lumen diameters and average volumes were larger when nitroglycerin spray was administered sublingually before scanning. Their study appears in the January issue of the American Journal of Roentgenology.

DSCT matches angiography for stenosis detection -- even in fast hearts

By Jerry Ingram

Dual-source CT (DSCT) offers diagnostic accuracy comparable to that of invasive coronary angiography when it comes to identifying significant coronary artery stenoses, according to researchers from Germany. To test whether DSCT could match angiography in accuracy, they examined patients with suspected coronary artery disease and found DSCT angiography offered high sensitivity for detecting stenosis.

MDMA abuse linked to valvular heart disease

By Reuters Health

NEW YORK (Reuters Health), Nov 29 - The use of the recreational drug MDMA (3,4-methylenedioxymethamphetamine), commonly known as ecstasy, can cause cardiac valvulopathy in young adults, investigators in Belgium report in the November issue of the American Journal of Cardiology. The group examined the potential clinical ramifications of MDMA use by comparing echocardiographic data from 29 subjects who had used MDMA for at least six months and 29 age-matched controls.
