[目的]探讨MRI水激励(selecitve water excitation,WATS)技术在评价军事训练性髌软骨损伤中的临床价值,以提高对MRI水激励技术的认识.[方法]对10例正常人及8例军事训练性髌软骨损伤患者的MRI影像学表现进行分析,重点观察髌软骨及软骨下骨髓的改变.所有受试者均采用轴位三维快速梯度回波水激励序列(3D-FFE-WATS)扫描.[结果]3D-FFE-WATS序列能够清晰显示髌软骨结构,正常髌软骨可见3层结构.8例髌软骨损伤患者的MRI表现主要为髌软骨全层缺损(5例)或软骨部分缺损(3例),所有患者均伴有软骨下骨挫伤,其中4例伴关节积液,1例伴髌骨外侧脱位,1例伴关节腔游离体.[结论]轴位MRI 3D-FFE-WATS显像可以清晰显示关节软骨的结构,对于髌软骨损伤的检出率高,可用于临床常规检查.

[Objective] To explore the clinical value of water excitation technique in the assessment of military training re-Lated patellar cartilage injury. [Methods] The MRI changes of cartilage and subcartilage bone were analysed retrospectiv-ely in 10 normal subjects and 8 cases of military training related patellar cartilage injury. Axial MR scanning of knee was performed in all subjects, using 3D-FFE-WATS. [Results] The structure of patellar cartilage was clearly displayed on MR images using 3D-FFE-WATS. On 3D-FFE-WATS images, normal patelLar cartilage showed 3 laminae. The abnormal MR appearances of 8 patients with military training related patelLar cartilage injury showed totally defect of the cartilage in 5 patients and superficial defect of the cartilage in 3 patients. SubcartiLage bone contusion was found in all cases. Joint effu-sion was observed in 4 cases. Corpus liberum and lateral patellar dislocation was found in 1 ease, respectively. [Condu-sions] 3D-FFE-WATS, axial MRI scanning can clearly display the structure of normal patellar cartilage. It has high abili-ty in finding the cartilage damage of the patelLar, therefore 3D-FFE-WATS can be used in routine clinical patellar carti-lage examination.
