Abstract

Interleaved black/bright imaging (IBBI) is performed using a magnetic resonance (MR) scanner wherein the black blood module of the IBBI includes: applying a first flow sensitization gradient; applying a spoiler gradient after applying the first flow sensitization gradient; applying a second flow sensitization gradient after applying the spoiler gradient wherein the second flow sensitization gradient has area equal to the first flow sensitization gradient but of opposite polarity; applying a slice selective radio frequency excitation pulse after applying the spoiler gradient; and performing a MR readout after applying the second flow sensitization gradient and after applying the slice selective radio frequency excitation wherein the readout acquires MR imaging data having blood signal suppression in the region excited by the slice selective radio frequency excitation pulse. The MR imaging data having blood signal suppression is reconstructed to generate black blood images, and MR imaging data generated by bright blood modules of the IBBI is reconstructed to generate bright blood images.
