摘要
目的:探讨低场强MRI在膝关节外伤手术中的指导作用。方法:对63例经临床手术或关节镜病理证实的膝关节外伤患者的MRI表现进行分析。结果:半月板不同程度损伤48例,MRI表现为半月板内出现线状、椭圆形、星型的高信号。前交叉韧带损伤21例,后交叉韧带损伤8例,侧副韧带损伤9例,表现为韧带的连续性中断、部分撕裂,内部出现线条样或片状异常信号。关节腔积液49例,MRI表现为关节腔内高T2加权像(T2WI)低T1加权像信号影。隐匿性骨折及骨挫伤19例,表现为骨质内条片状或大片状高T2WI信号。结论:低场强MRI在膝关节损伤的影像表现对临床手术有指导作用。
Objective：To explore the guideline effects of MRI with low electric field intensity on operation of knee joints. Methods： The MRI results of 63 cases with injury knee verified through operation or arthroscopes pathology were retrospectively analyzed. Results：In 48 cases with meniscus injury, MRI showed that there were abnormal linar, strip and star shape hyperintense in meniscus. In 21 cases with anterior cruciate ligaments injury,8 cases with the posterior eruciate ligament injury and 9 cases with collateral ligaments injury, MRI showed that the ligaments continuity were injury and tearing and abnormal linar and strip sign existed inside of ligament. In 49 cases with knee joint effusion, MRI showed that high T2 weighted images （T2WI） and low T1 weighted images signal appeared in cavity of joints. In 19 cases with hiding bone fracture, the linar and strip high T2WI signal of MRI were detected in scIerotin. Conclusions：The results of MRI with low electric intensity for injured knee joints have guideline value for clinical operation.
