Three-dimensional (3D) T1 weighted (T1w) turbo spin echo (TSE) sequence has demonstrated its value for intracranial vessel wall imaging (IVWI), but its long scan time has hampered wider clinical translation. In this study, a 4-minute 3D T1w TSE sequence was optimized and combined with wave encoded parallel imaging and compressed sensing (PI-CS) reconstruction for whole brain isotropic 0.6mm IVWI. This approach improved the image quality and robustness of IVWI in comparison to the Cartesian encoded PI-CS approach in healthy subjects. It demonstrated promising potential for further clinical evaluation.
