Combined imaging may be better identification of difficult-to-diagnose brain clots

University of Cincinnati (UC) neuroradiologists believe a brain imaging approach that combines standard magnetic resonance imaging (MRI) scans with specialized contrast-enhanced techniques could lead to more effective diagnoses in patients with difficult-to-detect blood clots in veins of the brain.

James Leach, MD, reports these findings in the April issue of the American Journal of Neuroradiology. This is the first study to correlate the clinical importance of data gleaned from standard MRI scans and detailed contrast-enhanced imaging techniques in patients with chronic thrombosis (blood clots) in veins of the brain.

"Detailed contrast-enhanced techniques produce more defined distinctions between abnormal and normal veins in the membrane around the brain," explains Leach, a neuroradiologist and associate professor at UC and principal investigator of the study. "Evaluating patients using a combination of imaging tools could give us a better understanding of the disease process."
