Dr. Goyal is the Director of Research, Department of Diagnostic Imaging. His main research interests are: Imaging in hyperacute stroke, treatment strategies for hyperacute stroke, image post-processing and teleradiology solutions, and minimally invasive MR guided procedures. His recent works include assessment of carotid stability on CT angiography, use of iPhone to diagnose acute stroke, and increasing efficiency in treatment of hyperacute stroke.
He is a coinvestigator in the CATCH (CT And MRI in the Triage of TIA and minor Cerebrovascular events to identify High risk patients) study. He is also a coinvestigator in a recently submitted grant application, identifying novel approaches to optimizing arterial imaging interpretation for predicting and measuring recanalization whatever the treatment and to optmize parenchymal imaging interpretation for prediction of early neurological recovery after recanalization using Serial CT angiography, INTERRSeCT.
He is currently working on a scoring system (modified ASPECTS) to improve the ability to detect early changes of ischemic stroke on oncontrast CT scan and reduce interobserver variability. He is site PI for the START Trial (Clinical Outcome in Acute Stroke Treatment After Image Guided Patient Selection for Interventional Revascularization Therapy). Dr. Goyal is also the neuroradiology Residency Program Director and under his supervision several fellows have successfully trained in Diagnostic and Interventional Neuroradiology.
