Abstract:
Objective:To investigate the value of magnetic resonance image (MRI) sagittal three-dimensional fat suppression rapid phase shifting gradient echo (3D-FS-FSPGR) sequence in the diagnosis of knee joint cartilage injuries.
Methods:42 cases (44 knees joint cartilage injuries )in our hospital from February 2016 to May 2017 were selected, MRI scan was performed by 3D-FS-FSPGR scan.Arthroscopy was performed within one week. At the same time, 11 knee joint cartilages of 10 patients were examined pathologically.
Results:The sensitivity, specificity and accuracy of 3D-FS-SPGR sequence diagnosis for knee joint cartilage injuries were 96.67%, 96.57% and 92.05% respectively; The Kappa value of 3D-FS-SPGR sequence and arthroscopy knee joint cartilage classification were 0.803 (P<0.05), with good consistency; The Kappa value of routine sequence and arthroscopy knee joint cartilage classification was 0.488 (P<0.05), with general consistency; The Kappa value of the 3D-FS-SPGR sequence and pathological grading of articular cartilage was 0.635 (P<0.05), with acceptable consistency.
Conclusions:The 3D-FS-SPGR sequence is of high diagnostic value in cartilage damage and grading of knee joint, and is consistent with pathological findings.
