MRA, SWI and QSM are important for identifying thrombus, hemorrhage, CMBs and assessing oxygen saturation and iron deposition in diseases such as stroke and traumatic brain injury (TBI). Practically, it is important to acquire these data with sufficient resolution, good SNR, co-registered and rapidly. Therefore, we developed a 3D interleaved GRE sequence that produces MRA, SWI, R2* and QSM for imaging arteries, veins and the basal ganglia in 4 minutes at 3T for the entire brain with a resolution of 0.67x1.33x2.0mm³. Five healthy volunteers’ data were acquired approved by the local IRB to demonstrate the utility of this approach.
