Three dimensional whole brain and neck vessel wall imaging of high resolution facilities the imaging of intracranial and extracranial arteries in stroke patients. However, its clinical usage is hindered by long scan time. Using a 32-channel head and neck coil system specially designed for high SNR, this work investigated the feasibility of highly accelerated parallel imaging equipped with optimally selected uniform subsampling pattern based on 3D G-factor calculated from separate calibration data and joint sparsity based denoising at acceleration factor of 6.
