Richard Aviv

Biography

Dr. Aviv's principal areas of research are investigating multiple sclerosis and stroke using advanced computed tomography (CT) and magnetic resonance imaging (MRI). Ongoing research activities include: exploring the link between cortical perfusion and cognition in multiple sclerosis (MS) comparative perfusion techniques in MS perfusion as a surrogate of cortical disease severity in MS prospective study of CT permeability as a predictor of hemorrhagic transformation study of image reconstruction algorithms for CT dose reduction computational models of CT perfusion thresholds for predicting tissue fate study exploring vascular etiology in MS using magnetic resonance perfusion markers of disease severity as surrogate markers of disease burden and correlation with cognitive impairment CT angiography "spot sign" predicting primary hematoma expansion STOP-IT Study (spot sign for predicting and treating intracerebral hemorrhage growth), investigating the effect of recombinant factor 7 on hematoma study of spot sign in intracerebral hemorrhage (SPOTLIGHT; co-principal investigator, steering committee member and study radiologist) collaborative study of angiogenesis in primary brain tumors collaborative projects studying prediction of metastasis response to stereotactic radiotherapy using MRI dynamic susceptibility contrast and permeability imaging.
