Intracranial atherosclerosis is an important cause of ischemic stroke. Imaging techniques depicting the intracranial arterial vessel wall and its pathology are therefore important, like the Magnetization-Preparation Inversion Recovery (MPIR)-TSE sequence at 7.0 Tesla MRI. However, this sequence has small coverage, limiting assessment of peripheral arteries. In this study we adapted the MPIR-TSE sequence to obtain whole-brain coverage, with different contrasts weightings. These new sequences were able to depict vessel walls throughout the brain, at a level of detail almost equal to the limited-coverage sequence, and can be used both in future studies regarding intracranial arterial pathology, and in clinical practice.
