Assessment of vessel lumen and wall and plaques lesions is important in management of patients with atherosclerosis. Conventional MR imaging typically requires long scan times to acquire MRA and vessel wall imaging (VWI), respectively. In this work, we present a new multi-contrast blood imaging method named BRIDGE (bright and dark blood images with multi-shot gradient-echo-planar imaging), which simultaneously acquires MRA and VWI in a single acquisition. Initial results with volunteers and patients showed that comparable image quality to conventional methods could be acquired in a short time, allowed simultaneous assessment of luminal changes and vulnerable plaques in a single acquisition.
