Abstract
A magnetic resonance method and system are provided for projection MR imaging of vascular structures within a subject, with scan times that are shorter than those needed for conventional techniques. Image acquisition sequences are synchronized with heartbeat cycles of the subject, and are configured to generate image data having a reduced spatial resolution in the projection direction perpendicular to a preselected projection plane. A reduction factor F quantifies this reduced resolution, such that the number of data acquisition sequences provided within each heartbeat cycle is F times as many as a comparable imaging protocol that generates full-resolution data. The total scan time can be reduced by a factor of F with negligible degradation in the projection image quality.
