A single scan of multi-slab, multi-echo acquisition can simultaneously provide 3D time-of-flight (TOF) MR angiography and susceptibility-weighted imaging (SWI) MR venography, which allows for the assessment of vascular injury in the form of cerebral microbleeds in association with arteries and veins. However, the acquisition for high-resolution multi-slab 3D TOF-MRA/SWI with whole brain coverage takes over 10 minutes to acquire at 3T. In this work, we developed a 3D multi-slab, multi-echo acquisition for TOF-MRA/SWI with multi-band acceleration to reduce acquisition time and compared the resulting TOF-MRA and SWI images in patients with radiation-induced microbleeds.
