Analysis of Bolus Arrival Time in Moyamoya Disease Using Ultra-Fast 3D Dynamic Contrast-Enhanced MR Imaging by GRASP technique
Motivation: To better understand the hemodynamics in moyamoya disease (MMD), high temporal and spatial resolution DCE-MRI using GRASP technique could estimate bolus arrival time (BAT) in MMD. Goal(s): To find optimal condition for measuring BAT and to elucidate clinical value of BAT on MMD. Approach: Thirty-seven MMD patients were included. Images with 5, 8, 13, and 21 spokes/frame were post-processed to derive time-intensity curves and estimate BATs. Results: Using the optimal 13 spokes/frame, BATs were delayed on the side with severe stenosis/occlusion and were in the order of MCA M2, basal ganglia, thalamus, and choroid plexus. Impact: Bolus arrival time in moyamoya disease estimated by using high temporal and spatial resolution 3D dynamic contrast-enhanced MR imaging using GRASP technique facilitates our understanding of the hemodynamics in moyamoya disease by elucidating regional difference.
