Computed tomography (CT) and magnetic resonance imaging (MRI)perfusion and permeability in stroke, multiple sclerosis and tumor, neuroradiology.

  • Functional magnetic resonance imaging
  • Functional computed tomography imaging
  • Perfusion and permeability

MRI/CT perfusion, permeability, Multiple Sclerosis, stroke, tumor 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 (MR) 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 ICH growTh), investigating the effect of recombinant factor 7 on hematoma
  • study of spot sign in ICH (SPOTLIGHT; co-PI, steering committee member and study radiologist)
  • collaborative projects studying prediction of metastasis response to stereotactic radiotherapy using MRI dynamic susceptibility contrast and permeability imaging
