Synopsis

Keywords: Vessels, Data AcquisitionPulsatile motion of intracranial arteries may provide useful diagnostic information of intracranial vascular pathology. We develop an isotropic 3D black-blood whole brain MRI method for assessment of intracranial vascular pulsation. Comparison of the black-blood with 2D bright-blood PC-MRA and assessment of luminal boundary changes across the cardiac cycle suggest that pulsation of large intracranial arteries can be detected and measured by black-blood cine MRI.
