Abstract: 【Abstract】 Objective To investigate the utility of the radial MR imaging in the interrogation of meniscal lesions and its instructional value for clinical management...Methods In the study,.we retrospectively evaluated 58 patients who underwent MR imaging of the knee and arthroscopy..The radial and conventional images were interpreted separately and then in combination,and findings were compared with arthroscopic reports. Results There was no statistical difference between the interpretations of the radial and conventional images. When the interpretations of the radial and conventional images were combined, the sensitivity and specificity improved slightly. Sensitivity and specificity for meniscal tears were accurate diagnosed by conventional scanning method (radial and conventional scanning method) were 62.50% (62.50%), 80.90% (95.23%), 72.72% (78.78%); 98.00% (94.00%), 89.19% (78.37%), 92.30% (92.30%). Sensitivity and specificity for meniscal tears were accurate diagnosed by conventional scanning method (radial and conventional scanning method) were 64.28% (78.57%), 76.47% (88.00%), 82.35% (94.11%), 97.72% (96.45%), 92.68% (85.36%), 97.56% (97.56%). Conclusion The radial images increased the conspicuity of meniscal tears. When the interpretations of the radial and conventional images are combined, the diagnostic accuracy increases, the radial MR Imaging is helpful means for the evaluation of meniscal tears.
