Claim One:
1. A method comprising: performing a plurality of repetitions of a local excitation black blood imaging (LOBBI) sequence using a magnetic resonance scanner, wherein each repetition of the LOBBI sequence includes: applying a first flow sensitization gradient for in-plane flow sensitization with a 90° radio frequency pulse preceding the first flow sensitization gradient and a −90° tip-up radio frequency pulse following the first flow sensitization gradient, applying a spoiler gradient after applying the first flow sensitization gradient, applying a slice-selective radio frequency excitation pulse after applying the spoiler gradient, applying a second flow sensitization gradient for in-plane flow sensitization after applying the spoiler gradient wherein the second flow sensitization gradient has area equal to the first flow sensitization gradient but of opposite polarity, and performing a magnetic resonance readout after applying the second flow sensitization gradient and after applying the slice-selective radio frequency excitation, wherein at least a portion of the second flow sensitization gradient is applied after applying the slice-selective radio frequency excitation pulse; and between successive repetitions of performing the LOBBI sequence, performing at least one interposed repetition of a bright blood angiography sequence using the magnetic resonance scanner.
