Abstract:
[Objective]To compare the value of the MR imaging and arthroscopy for detecting articular cartilage erosion,and to evaluate the clinical effect of MR imaging on the correct diagnosis in the early stage of articular cartilage lesion.[Method]Twenty-six patients(27 knees)with persistent knee pain who were scheduled for arthroscopy underwent MR scanning,including 3D FS-FSPGR,FSE PDWI and FSE T1WI sequences.The results of each sequence were then compared with the arthroscopic findings.[Result]Using arthroscopic results as the standard of reference,the 3D FS-FSPGR images had the higher sensitivity(96.5%)and accuracy(95.0%)than the standard MR imaging,the 3D FS-FSPGR sequence was well consistent with the result of arthroscopic,Kappa value was higher(0.776)than the other sequences(P
