Bright- and black-blood imaging are key contrasts for the assessment of lumen and vessel wall integrity in aortic MRI. These contrasts are usually acquired separately, resulting in long and inefficient examinations. Here we extend a previously introduced motion-compensated interleaved acquisition (iT2Prep-BOOST) to produce high-quality co-registered 3D bright- and black-blood images from a short predictable scan of ~8min. The proposed iT2Prep-BOOST approach resulted in bright-blood images with improved contrast compared to conventional bSFFP images, and black-blood images with increased volumetric coverage and resolution compared to conventional HASTE images, showing promise for a comprehensive assessment of aortic disease from a single scan.
