摘要
目的：确定MRI技术诊断膝关节损伤的可靠性及敏感性及临床应用价值；材料与方法：应用SI-EMENSMAGNETON1．0T超导MR系统，采用头线圈或膝关节线圈，自旋回波（SE）序列，膝关节外旋15度，对31例膝关节损伤患者行T1T2加权，质子加权矢状位，冠状位扫描。结果：检查发现半月板损伤18例（占58．8％），其中内侧半月板损伤13例，外侧5例。前角损伤13例，后角损伤3例，前后角损伤2例，十字韧带损伤7例，占22．6％，侧副韧带损伤8例，占25．8％。结论：MRI技术诊断膝关节损伤具有较高的可靠性及敏感性。
Objective: To define the reliability,susceptibility and clinical use value of MR imaging diagnosis, of Knee injury. Methods: 31patients of Knee injury were scanned with the SE T1 WI,T2WI, PDM sagittal and coronal by using SIEMENS MAGNETON 1 .0T MR system with the head coil or the Knee coil. Results: In 18 cases of meniscal tear(58. 8 % ). 13 cases were medial mensical tear and 5 cases were lateral. 7 cases of cruciate ligament tear(22. 6 % ) and 8 cases of collateral ligament tear (25. 8 % ). Conclusions: MR imaging possesses high sensitivity and specificity to diagnostic menical injury of the Knee, such as absence of normal hypointense meniscal triangle in sagittal view or linear high signal in T1, WIand T2WI. The meniscal injury were classified into grade Ⅲ according to Stoller method. The diagnosis of ligament and tendons injury were hign or low intensity in T2WI and avulsion injury(tibial end).
