Numerous diseases such as stroke, arteriovenous malformation (AVM), traumatic brain injury (TBI) and tumor evaluation require detailed vascular information for the best diagnostic interpretation1-4. Being able to collect both MR angiography and venography with sufficient SNR, CNR and co-registration in short time is critical for these diseases, especially for emergency patients. In this work, we developed a rapid 3D interleaved GRE sequence to acquire these vascular images simultaneously. Co-registered MRAV, MRA, QSM and tSWI for imaging arteries, veins and basal ganglia in 4 minutes and 24 seconds on a NMS 1.5T system covering the whole brain with 0.67×1.33 × 2.7 mm3 resolution
