The double inversion fast spin echo (DBIR-FSE) pulse sequence is used to generate black blood images of the heart but is known to be a single slice technique due to a non-selective inversion pulse used for magnetization preparation. In this work we present a multi-band version of DBIR-FSE which can generate multiple slices acquired at the null point of blood and exhibits better SNR efficiency. A radial version of the proposed sequence can generate anatomical images of multiple slices along with individual echo images at different TE's and T2 maps in a single breath-hold.
