Medical images unlikely to change risky behavior, study shows

By Donna Domino

If you show an obese person a medical image of their plaque-clogged arteries, will it help motivate them to get more exercise? Not necessarily, although you might have better luck getting smokers to change their ways, according to a new review of literature from the Cochrane Collaboration.

Italian researchers cut gadolinium dose -- as well as NSF risk

By Wayne Forrest

A half dose of a commercially available MRI contrast agent works as well as a full dose in patients with acute myocardial infarction, according to Italian researchers. The findings show it's possible to achieve shorter imaging times while protecting renally impaired cardiac patients at risk for nephrogenic systemic fibrosis (NSF).

Imaging shows that even mild COPD reduces cardiac efficiency

By Eric Barnes

Even mild cases of chronic obstructive pulmonary disease (COPD) have serious effects on the heart and blood circulation, according to a study to be published Thursday in the New England Journal of Medicine. The analysis found that the same problems long associated with severe disease are also present in milder cases.

Ultrasound-based technique shows promise for atrial fibrillation

By Erik L. Ridley

If researchers at the University of Virginia (UVA) Health System have anything to say about it, fluoroscopy may one day no longer be needed to guide catheter ablation for atrial fibrillation. The UVA study team has developed a new catheter ablation technique that combines intracardiac echocardiography and electroanatomic mapping.

Analysis favors coronary CTA over stress MPS for chest pain

By Eric Barnes

In most chest pain patients, coronary CT angiography (CTA) surpasses its rival -- stress myocardial perfusion scintigraphy (MPS) -- for diagnosing coronary artery disease, according to the results of a new model analysis comparing the two techniques.

CTA motion model aims to improve cardiac function analysis

By Eric Barnes

Dutch researchers used an automated coronary artery motion model to analyze cardiac function from electrocardiogram-gated coronary CT angiography (CTA) data. The method promises to improve cardiac function analysis and reconstruction interval selection, and even provide new information on coronary artery motion at different heart rates.

DSCT edges out 64-slice CT in coronary artery imaging

By Eric Barnes

Coronary CT angiography performed on dual-source CT (DSCT) confers a slight advantage in image quality with slightly fewer nondiagnostic vessel segments compared to 64-detector-row CT. Calcification remains a challenge with both types of scanners, but it's slightly less problematic with dual-source systems, say researchers from the University of Rome.
