title: [Application value of FS-3D-FISP sequence in the diagnosis of ankle cartilage injury].
abstract: OBJECTIVE
  To compare several sequences of MRI and arthroscopy for detecting the ankle articular cartilage lesions and to evaluate the clinical outcome of special sequence of FS-3D-FISP.
  
  
  METHODS
  Forty patients (41 ankles) with iterative ankle pain who were scheduled for arthroscopy underwent MR scanning, including FS-3D-FISP, FSE T2WI and FSE PDWI sequences. The results of each sequence were then compared with the arthroscopic findings.
  
  
  RESULTS
  Using arthroscopic results as the standard of reference, the FS-3D-FISP images had the higher sensitivity (92.86%) than the other two sequences. The FS-3D-FISP sequence was well consistent with the result of arthroscopy. Kappa value (0.7590) was higher than the other two sequences (P < 0.01).
  
  
  CONCLUSIONS
  As a favorable scanning sequence, FS-3D-FISP imaging can show the early-stage pathological changes of articular cartilage and it has an excellent correlation with the arthroscopic findings. A 3-D reconstruction is helpful to determine the location and the degree of lesion and obtain a more accurate classification to guide clinical decisions.
