Hemodynamic Evaluation of Cerebral Arteriovenous Malformations with Combined 4 D Flow and Perfusion MRI

velocities and blood flow in the AVM feeding arteries, contralateral arteries, draining veins, and straight sinus. Figure 3: Perfusion ratios (CBF, CBV, and MTT) in four pairs of ROIs (Ni/Nc, Hi/Hc, Pi/Pc, and Ri/Rc) between the affected and nonaffected hemispheres. Figure 1: 4D flow visualization (pathlines) and analysis plane positions for flow quantification in a left medial occipital AVM (left); Perfusion model with four ROIs at the ipsilateral (affected) and contralateral (non-affected) hemispheres for perfusion ratio analysis (middle); CBF image with the ROI labels (right). 1404 Hemodynamic Evaluation of Cerebral Arteriovenous Malformations with Combined 4D Flow and Perfusion MRI Can Wu, Timothy Carroll, Sameer Ansari, Amir Honarmand, Parmede Vakil, Michael Hurley, Bernard Bendok, James Carr, and Michael Markl Biomedical Engineering, Northwestern University, Chicago, IL, United States, Radiology, Northwestern University, Chicago, IL, United States, Neurological Surgery, Northwestern University, Chicago, IL, United States
