It is essential to avoid small vessels during stereo-electroencephalography (SEEG) electrode implantation. In this study, we proposed a 6-fold Compressed sensing accelerated, 5cm/s Low velocity encoded, 0.75mm Isotropic resolution Phase contrast Magnetic Resonance Angiography (CLIP-MRA). In CLIP-MRA, the compressed sensing based acceleration method was shown to achieve better image quality or shorter scan duration compared to parallel imaging based acceleration. CLIP-MRA was able to display not only cortical arteries and veins simultaneously, but also vessels in the skull. Safety and effectiveness of CLIP-MRA utilized preoperative SEEG planning were evaluated on a small patient cohort.
