An increasing the number of MPG directions causes prolongation of scan time. Recently, MultiBand SENSE (MB-SENSE) has been developed to allow the simultaneous acquisition of multiple slices and it enabled to shorten the scan time. Our purpose in this study was to investigate whether super multi-directional DTI using MB-SENSE is more useful for evaluation of lumbar nerve disorders than conventional method. An increasing the number of MPG directions improved its continuity and accuracy in tractography and tended to decrease the standard deviation of FA values.
