摘　　要：目的探讨高分辨率CT关节造影(high resolution CT arthrography,HRCTA)在诊断膝关节病变的应用价值。方法 50例疑诊膝关节病变患者,行HRCTA扫描及多平面重建成像,多角度观察膝关节病变的影像表现。结果HRCTA诊断半月板损伤32例,表现为损伤部位可见高密度造影剂充填;诊断关节软骨损伤18例,表现为关节面软骨变薄、表面毛糙、部分缺损;诊断交叉韧带损伤12例,表现为密度及形态异常、损伤处造影剂渗入;诊断盘状半月板8例,表现为半月板增宽、增厚;诊断半月板囊肿6例,表现为与半月板相邻的小囊袋状高密度影;诊断腘窝囊肿10例,表现为腘窝内与关节腔相通的高密度囊袋状影。结论 HRCTA在膝关节病变诊断方面有较高临床价值,可为关节镜前筛查、制订治疗方案及术后评估提供重要参考。Objective To explore the value of the high resolution CT arthrography to the diagnosis of knee joint lesions. Methods Fifty patients with suspected knee joint lesion underwent high resolution CT scanning, the raw data were reconstructed with multi-plane techniques, and the lesions were observed from various angles. Results In fifty cases, 32 cases were diagnosed as meniscal injury, demonstrating contrast agent filling in the injured part, 18 cases were diagnosed as articular cartilage injury, demonstrating articular cartilage thinning, rough surface and partial cartilage defect, 12 cases were diagnosed as cruciate ligament injury, demonstrating abnormal density and morphology, contrast infiltration from the injured part, 8 cases were diagnosed as discoid meniscus, demonstrating the meniscus broadening and thickening, 6 cases were diagnosed as meniscal cyst, demonstrating high density in its adjacent meniscus, and 10 cases were diagnosed as popiiteal cyst, demonstrating high density saclike shadow in popliteal fossa communicating with knee joint cavity. Conclusion High resolution CT arthrography has a high clinical value to the diagnosis of knee joint lesions, and plays an important reference role in preoperative screening, treatment plan and postoperative assessment.
