Echo may be more accurate than ECG for triggering cardiac scans

By Eric Barnes

Real-time ultrasound could offer significant advantages over the electrocardiogram for triggering heart scans, according to a preliminary study from the University of Michigan in Ann Arbor. The authors' ultrasound technique could potentially improve the quality and consistency of cardiac imaging with CT and MRI.

Long-term anticoagulant users show elevated coronary, aortic calcium

By Eric Barnes

CHICAGO - Patients who take oral anticoagulants may risk developing significant coronary and aortic calcification. In a study that casts a wary eye on the routine use of the vitamin K antagonists such as warfarin, researchers from Aachen, Germany, found that long-term oral anticoagulant therapy was independently associated with increased calcium scores and valvular calcium deposits.

Coronary CTA requires dedication, 64-slice minimum

By Tracie L. Thompson

CHICAGO - Cardiac imaging may have slipped away from radiology in stages over the years, but radiologists can capture the boom in coronary CT angiography if they move fast, train hard, and plan to use at least a 64-slice scanner. Those were some of the views shared by leading practitioners during a lively and opinionated keynote and panel discussion Tuesday at the RSNA meeting.

Preablation CTA may avoid complications

By Tracie L. Thompson

CHICAGO - As electrophysiologists perform more pulmonary vein isolation procedures to treat atrial fibrillation, preprocedural CT angiography may help avoid potentially fatal complications by showing anatomic variants and proximity of a vulnerable esophagus, according to a presentation Monday at RSNA 2005.

64 CT slices beat 16 for stenosis and diagnosis of heart disease

By Eric Barnes

CHICAGO - Due to its superior z-axis resolution, 64-slice CT may do a better job than 16-slice in detecting in-stent stenosis, researchers reported on Sunday at the RSNA meeting. Another group found that 64-slice CT did not visualize vessels significantly better than 16-slice, but did improve diagnostic accuracy.

Cardiac CT strategies cut dose, keep image quality

By Eric Barnes

By definition, symptomatic screening patients deserve the lowest possible CT dose. For that matter, "as low as reasonably achievable" (ALARA) is a wise dosing strategy for symptomatic heart patients, too. A look at the diagnostic question at hand and adherence to a few scanning principles can often reveal opportunities for significant dose savings, according to a recent presentation.
