86 anterior and 37 superior acetabular labral tears,
including 30 stage II and 93 stage III labral tears,
were confirmed by hip arthroscopy(Fig.
The results of MRA for diagnosing different regions and Czerny stages of acetabular labral tears were shown in Table 1 and Table 2.
NPV and accuracy of MRA for diagnosing anterior and superior acetabular labral tears were 93.02% and 89.19%,
78.57% and 95.24%,
96.39% and 91.67%,
64.71% and 93.75%,
91.00% and 93.00%,
NPV and accuracy of MRA for diagnosing Czerny stage II and III labral tears were 83.33% and 94.62%,
98.24% and 97.20%,
89.29% and 96.70%,
97.09% and 95.41%,
96.00% and 96.00%,
The NPV of MRA in diagnosis of superior acetabular labral tears was significantly higher than that of anterior labral tears (P＜0.05),
while no significant differences were found in sensitivity,
PPV and accuracy (P＞0.05).
There were no significant differences in sensitivity,
NPV and accuracy of MRA for diagnosing between Czerny stage II and III labral tears (P＞0.05).
