Dose studies delve into coronary CTA

VIENNA - At the 2008 European Congress of Radiology (ECR) on Saturday, researchers presented a pair of studies that examined the radiation dose of coronary CT angiography (CTA). The first compared the dose of 64-slice CT to that of dual-source CT, and the other examined coronary CTA dose data from a multicenter trial.

Automated patient-based contrast application cuts CTA contrast volume, risk

VIENNA - A work-in-progress application that bases coronary CT angiography (CTA) contrast dose and timing on a patient's individual cardiac output significantly reduces contrast media use and, by extension, the risk of nephropathy, according to a study presented Friday at the 2008 European Congress of Radiology (ECR).

Dual-source CT edges into cardiac SPECT turf

U.S. researchers will use this week's European Congress of Radiology in Vienna to present research that shows dual-source CT making inroads into cardiac functional imaging, an area currently dominated by SPECT. The study moves dual-source coronary CT angiography closer to the holy grail of cardiac imaging -- a test that performs both morphological and functional analysis in a single scan.

Coronary calcification predicts future cardiac events in asymptomatic subjects

By Reuters Health

NEW YORK (Reuters Health), Jan 15 - The determination of coronary calcifications may help identify asymptomatic patients at risk for future MI or cardiac death, according to findings published in the January issue of the American Heart Journal. The reachers used electron beam CT to determine coronary calcifications, and calculated the Agatston score for quantification of coronary calcifications.

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.

Dual-source CTA improves temporal resolution for cardiac imaging

By Radiology Review

(Radiology Review) Dual-source CT angiography (CTA) enables noninvasive, functional cardiac analysis, including accurate assessment of left ventricular myocardial function and reliable evaluation of regional wall motion, according to a pilot study by German researchers.

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.
