Glutamate imaging better than MR spectroscopy in first 3 hours after ischemic stroke

Leesburg, VA, May 5, 2014--Glutamate imaging reveals ischemic lesions in the first 3 hours after stroke that are not distinguishable in T1-weighted and T2-weighted imaging.

Researchers using chemical exchange saturation transfer (CEST), an emerging MRI technology, have found that using glutamate with CEST shows high spatial resolution in vivo. The finding has the potential to speed diagnosis--and, therefore, treatment--in the critical first hours after a stroke.

"I have been interested in glutamate imaging since its inception," said researcher Zhuozhi Dai of Second Affiliated Hospital of Shantou University Medical College, Shantou, China. "Being able to evaluate glutamate in the brain could be of great benefit in the clinical setting."

Dr. Dai presented the study on Monday, May 5 at the 2014 ARRS Annual Meeting in San Diego, CA.

Founded in 1900, ARRS is the first and oldest radiology society in the United States and is an international forum for progress in radiology. The Society's mission is to improve health through a community committed to advancing knowledge and skills in radiology. ARRS achieves its mission through an annual scientific and educational meeting, publication of the American Journal of Roentgenology (AJR) and InPractice magazine, topical symposia and webinars, and print and online educational materials. ARRS is located in Leesburg, VA.
