A single volumetric SPGR sequence reconstructed with ESPIRiT compressed sensing reconstruction and two-point Dixon fat-water separation was added to routine hip MR arthrogram and compared to the conventional 3-plane 2D-FSE fat-saturated T1-weighted sequences in identification of hip pathology in 25 patients. SPGR compared favorably well with T1 FS, but failed to identify 3 subtle labral tears, 1 chondral delamination and 3 low-grade ligamentum teres tears, possibly due to increased blurring associated with SPGR, decreasing overall image quality of SPGR. The relative time saving of SPGR and ability to subsequently reformat data makes this a viable technique for hip MR arthrograms.
