Vascular disease such as arteriovenous malformations can be fatal and lead to brain damage if not detected early. To that end, time of flight angiography is an important tool to visualize vessels, especially the arteries with implications for treatment planning and follow-up. Similarly, susceptibility weighted imaging can be used to visualize veins due to its sensitivity to magnetic field inhomogeneities. However, high resolution TOF and SWI acquisitions can lead to clinically unfeasible scan times. Here, we propose to use compressed-sensing-accelerated high resolution TOF and SWI acquisitions at 7T in <15 minutes to visualize the vascular system of the whole brain.
