The DIR-FSE sequence is popularly used to assess plaque build up but is known to be a single slice technique due to a non-selective inversion pulse used in the DIR module. In this work we present a technique to improve the SNR efficiency of DIR-FSE sequences by multi-band excitation. The proposed technique can generate multiple slices at the exact null point of blood and the acquired data can be used to create upto 16 TE images and T2 maps for all the acquired slices.
