VIPR-ATR can produce 0.5mm isotropic resolution images
of the hip joint with SSFP tissue contrast which can be
reformatted in any orientation following a single 7.7
minute acquisition. This study compared VIPR-ATR with
two-dimensional fast spin-echo (2D FSE) sequences for
evaluating the hip joint in 24 patients. VIPR-ATR had
significantly higher (p<0.05) normalized SNR efficiency
for cartilage and fluid and significantly higher
(p<0.05) normalized CNR efficiency between cartilage and
other joint structures than 2D FSE sequences. VIPR-ATR
had similar ability as 2D FSE images for detecting
labral tears and improved ability for identifying
cartilage lesions within the hip joint.
