MRI

MRI performed at an unlimited specific absorption rate is safe in patients with some permanent pacemakers or implantable cardioverter/defibrillator systems, as long as precautions are taken, according to a study from Israel.

In rectal cancer, mortality rates are high and prognoses are generally poor, owing to the strong risk of metastases and local recurrence.

An unconscious, outwardly unresponsive patient apparently was capable of understanding and responding to certain commands as measured by functional MRI.

No fewer than eight medical specialty societies, including the American College of Radiology and a section of the American College of Cardiology, signed off on a report covering clinical appropriateness criteria for cardiac CT and MR. In other reports, a cardiologist proposes an imaging fellowship for cardiology, and a radiologist describes a strategy to win the coronary CT angiography turf war.

Cardiologists will become increasingly dependent on angiograms generated using CT and MR over the next three years, according to a report released by IMV Medical Information Division, a Des Plaines, IL, market research firm. Within that time, cardiologists predict that CT angiography will take the place of SPECT and cardiac catheterization for evaluating seven of 11 major cardiac conditions.

Two investigative studies have found that MR angiography at 3T produces quality images of the kidneys and excellent cardiac cine images. Researchers used high parallel imaging factors and a 32-element phased-array coil to increase spatial resolution and anatomic coverage.

An international multicenter trial has validated the Edmonton Protocol for islet cell infusion as a fitting treatment alternative for certain patients suffering from type 1 diabetes. Results appeared in the Sept. 28 issue of The New England Journal of Medicine.
