Giant virtual reality chamber boosts 3D echo accuracy

By Eric Barnes

Have you ever diagnosed a three-foot-tall 3D heart? Talk about cardiomegaly. Researchers from the Netherlands who survived the experience found they could diagnose valve defects that went unnoticed in a standard 2D exam. At the 2007 Computer Assisted Radiology and Surgery (CARS) meeting in Berlin, Anton Koning, Ph.D., from Erasmus University Medical Center in Rotterdam discussed how 3D visualizes complex pathology of the heart and how image display can be improved with different kinds of VR (virtual reality) systems.

Living near busy road may promote atherosclerosis

By Reuters Health

NEW YORK (Reuters Health), Jul 17 - The closer a person lives to heavy traffic, the more likely he or she is to have atherosclerosis, also referred to as "hardening of the arteries," a chief risk factor for heart disease and stroke, German researchers report. While several studies have linked air pollution with particulate matter to a greater risk of heart attack, there is little evidence on whether this is due to short- or long-term exposure, the team notes in the journal, Circulation.

Two-segment CTA reconstruction aids images, not accuracy

By Eric Barnes

For patients with faster heart rates, the use of two-segment reconstruction improves image quality at 64-slice coronary CT angiography (CTA), according to a study from Germany. Among all patients, however, accuracy was not improved using two-segment when compared to single-segment reconstruction.

CT finds high-risk plaque with nanoparticle contrast

By Eric Barnes

A new animal study by researchers in the U.S. and France brings intriguing new possibilities to CT with its use of a nanoparticulate contrast agent administered before scanning to detect unstable atherosclerotic plaques. The group aims to someday detect human plaques at the greatest risk of rupture while there is time to prevent it.

Cardiac function impaired among smokers, even when they're young and fit

By Reuters Health

NEW YORK (Reuters Health), Apr 12 - There is little information regarding the effects of smoking on cardiac function in young adults, researchers from Poland note in a new study published in Chest. Their goal was to use echocardiography to determine multiple measures of left and right ventricular diastolic function, and to see if smoking caused functional impairment.
