摘要
目的:研究膝关节半月板及交叉韧带撕裂的磁共振(MRI)检查方法,优化扫描程序。方法:收集140例经关节镜证实的膝关节外伤病例,回顾性研究不同MRI扫描序列组(1个试验组和5个对照组)诊断半月板及韧带撕裂的准确性。结果:试验组诊断半月板和交叉韧带撕裂的准确性均大于其他对照组(P<0.05)。Osag-PDWIfs的诊断准确性较OsagT2WIfs好(N=192,P=0.000),CorPDWIfs明显优于CorT1WI(N=192,P=0.000)。试验组诊断内侧半月板撕裂准确性较外侧半月板好(N=192,P=0.000),诊断后交叉韧带撕裂准确性较前交叉韧带好(N=192,P=0.000)。结论:对于半月板及交叉韧带撕裂,本研究中试验组较其他试验组准确性好,为较优化的MRI序列组合,推荐其作为膝关节外伤的常规扫描方法。
Purpose： To optimize the MRI protocols in examination of patients with crucial ligament and/ or meniscal tears in knee. Methods： One hundred and forty cases of knee injury were divided into test group and control groups （the 1st - 5th） in this study. All cases had undergone arthroscopy, and the sensitivities, specificities and accuracies between the test group and different control groups were evaluated retrospectively. Results： The accuracy rate of test group with meniscal tears and crucial ligaments tears were obviously higher than all control groups（P 〈 0.05）, the accuracy of the OsagPDWIfs was better than OsagT2WIfs（N = 192, P = 0. 000）, and the accuracy of the CorPDWIfs was better than CorTIWI （N = 192, P = 0. 000）. The accuracy rate of test group with media meniscal and posterior crucial ligament tears were higher than that of lateral meniscal and anterior crucial ligament tears. （N = 192, P = 0. 000） . Conclusion： In this study, the MRI sequences in test group are optimized protocols, which should be recommended to be used in routine clinical applications of the injured knee.
