Brief Bio:

Dr. Aviv's principal areas of research are stroke and advanced computed tomography (CT) imaging. He is also involved in the following research activities:

prospective study of prediction of hemorrhagic transformation using CT permeability
study of image reconstruction algorithms for CT dose reduction
computational models of CT perfusion thresholds for predicting tissue fate
study exploring vascular etiology in multiple sclerosis 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-PI, steering committee member and study radiologist)
collaborative projects studying prediction of metastasis response to stereotactic radiotherapy using magnetic resonance imaging dynamic susceptibility contrast and permeability imaging.
