Our group recently developed simultaneous bilateral hip MR acquisition methods to reduce total imaging time and employ during longitudinal evaluations of hip OA. This study evaluated the ability of simultaneous bilateral 3D FSE Cube and MAPSS acquisitions to maintain relevant morphological information compared to unilateral acquisitions. The mean T1ρ and T2 values of the simultaneous bilateral MAPSS acquisitions were not significantly different from unilateral acquisitions and relaxometry map patterns were preserved. Additionally, our simultaneous bilateral hip protocol promoted high resolution 3D Cube images for morphological abnormality detection and reduced scan time by 40%, to under 30 minutes.
