Significant increase in use of CT, MRI and PET imaging over the last two decades

Among six large integrated health care systems between 1996 and 2010 there was a substantial increase in the use of advanced diagnostic imaging, including approximately a tripling of the use of computed tomography and nearly a quadrupling of the use of magnetic resonance imaging, as well as a substantial increase in estimated radiation exposure, according to a study in the June 13 issue of JAMA.

Ocular pulse amplitude reliable, safe screening test for carotid artery stenosis

A simple eye test may someday offer an effective way to identify patients who are at high risk for stroke, say researchers at the University of Zurich. They showed that a test called ocular pulse amplitude (OPA) can reliably detect carotid artery stenosis (CAS), a condition that clogs or blocks the arteries that feed the front part of the brain.

TAVI improves heart function, exercise capacity in patients with aortic stenosis

German researchers report success with transcatheter aortic valve implantation (TAVI) in patients with low-flow, low-gradient aortic stenosis-a special form of aortic stenosis that is difficult to treat. Results published in the April issue of Catheterization and Cardiovascular Interventions, the peer-reviewed journal of the Society for Cardiovascular Angiography and Interventions (SCAI), show that while all-cause mortality was high within the first six months, TAVI significantly improved heart function and exercise capacity in surviving patients.
