MRS shows cost-benefit strength for brain tumor diagnosis

By Jonathan S. Batchelor

In January 2004, the U.S. Centers for Medicare and Medicaid Services decided to continue the current noncoverage determination for proton magnetic resonance spectroscopy (MRS), stating there is inadequate evidence to conclude that MRS is necessary for diagnosing brain tumors. A research team from California, however, has presented compelling evidence that MRS use for brain tumor diagnosis is safe, accurate, and cost-effective.

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.

AuntMinnieTV: fMRI offers insight into retraining the brain

Functional MRI can provide important information on how the brain learns to conduct complicated motor-skills tasks, according to research presented at the 2004 RSNA show. The study could lay the groundwork for the development of prosthetic devices that paralyzed or stroke-impaired individuals could control using impulses in the brain.
