SWI detects brain injury in strokeRSS Feed

The brain injury seen in stroke could be better identified through the use of susceptibility-weighted imaging (SWI), research has indicated.

SWI is typically used as a secondary diagnosis tool for brain haemorrhages and to detect clots with cerebral artery infarctions.

However, a study at the University of California, Irvine, found that SWI could be used in classifying strokes.

Senior author Dr Mark D Mamlouk said: "Using SWI in patients with cerebral infarctions will decrease further imaging and its associated costs and radiation exposure, but more importantly this imaging technique will guide direct management in a timelier manner."

This follows findings from the University of Iowa, which found that antidepressants could be used to improve the physical recovery of people who have had a stroke.

Patients who underwent a short course of antidepressants after a stroke showed a significantly improved recovery in comparison to those treated with a placebo.
