Beyond ischemia, dobutamine stress MRI predicts major cardiac events

By Shalmali Pal

SAN FRANCISCO - Using dobutamine stress MRI (DSMR) to detect myocardial ischemia in coronary artery disease is hardly a new-fangled technique. But is the technique of any value for forecasting whether these patients will suffer from major adverse cardiac events? Yes, according to a presentation Friday at the Society for Cardiovascular Magnetic Resonance (SCMR) meeting.

MRI pulls double duty for PFO, atrial septal aneurysm

By Shalmali Pal

Patent foramen ovale (PFO) is a known cause of cerebral strokes, and studies have shown that the stroke rate is even higher if PFO is associated with an atrial septal aneurysm. Researchers from Europe suggest using contrast-enhanced dynamic MRI for detecting both conditions.

Study questions PFO and cerebral damage link in scuba divers

By Shalmali Pal

An ongoing debate in the scuba diving community involves people who have never suffered from type II decompression sickness, but who may still be at risk for cerebral damage because of "silent" gas embolisms. Previous studies have found that divers with patent foramen ovale are at a greater risk for gas embolisms. However, an MR study by researchers in Germany finds the risk may have been overstated.
