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 will present 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. The society was originally named the American Roentgen Society after its founder, Wilhelm Roentgen, who discovered the x-ray. ARRS has been an international forum for progress in radiology and is dedicated to the goal of the advancement of medicine through the science of radiology and its allied sciences. The goal of the ARRS is maintained through an annual scientific and educational meeting and publication of the American Journal of Roentgenology or AJR. ARRS is located in Leesburg, VA.
