Obese patients challenge efficacy of cardiac CTA
By Eric Barnes
VIENNA - Coronary CT angiography (CTA) is proving useful for evaluating most patients with suspected coronary artery disease, particularly since the introduction of 64-slice scanners. But information about CTA's performance in certain subpopulations, such as obese patients, is lacking. Researchers from Belgium studied whether coronary CTA was useful in this patient population, and presented their findings at the 2008 European Congress of Radiology (ECR).

Prospective gating drops cardiac CT radiation dose
By Brian Casey
VIENNA - Prospective gating has emerged as a promising method for reducing radiation dose in coronary CT angiography (CTA) studies. Monday at the European Congress of Radiology (ECR), Italian researchers confirmed previous results in using prospective gating to reduce dose to as little as 2.8 mSv per heart study, while a German group discussed its effort to further refine prospective gating by making it more accurate.

Dose studies delve into coronary CTA
By Eric Barnes
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
By Eric Barnes
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
By Eric Barnes
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 CTA cuts costs for chest pain care
By Eric Barnes
For patients with chest pain and a low risk of coronary artery disease (CAD), diagnosis of CAD based on coronary CT angiography (CTA) was more cost-effective than standard care, according to a new study from Argentina. The researchers examined the cost-effectiveness of a primary strategy of coronary CTA for evaluating CAD in low-risk patients with acute chest pain, compared to standard management for diagnosis.

How 64-slice CT saved my life: An administrator's story
By Jim Pittman
Coronary CT angiography (CTA) saved the life of Jim Pittman. Pittman, an administrator at Bedford Regional Medical Center in Indiana, shares his story with AuntMinnie.com -- how he decided to volunteer to undergo CTA on his hospital's new 64-slice CT scanner for technologist training, and how his decision ended up saving his life.
