q-space imaging (QSI) can allow us to measure water
molecular displacement in micro-meter order and also
there have been several attempts to verify the
microstructural changes of normal/abnormal human
subjects. Nevertheless, because of this long acqusition
time, the clinical applications of QSI might have been
largely limitted. Therefore, this study aimed to find a
feasible combination of q values to be shortening the
QSI acquisition for clinical use. For the evaluation, we
employed mean displacement (MD) which derived from
q-analysis of water molecular displacement distribution.
