As a widely used technique for cerebrovascular disease, the anatomical coverage of TOF-MRA is often limited in order to achieve a compromise between high spatial resolution and acceptable scan time. Compressed sensing (CS) is an effective technique for accelerating 3D acquisitions. In this study, we report the preliminary results of CS TOF-MRA for diagnosing head and neck arterial steno-occlusive disease by taking DSA as the reference standard. CS TOF-MRA provides a relatively large coverage, high resolution, good image quality and comparable diagnostic accuracy to DSA in the assessment of head and neck arterial stenoses within a reasonable acquisition time.
