【摘要】：目的 观察、分析临床诊断的跗骨窦综合征患者及正常志愿者踝关节X线、MSCT及MRI的影像学表现，探讨对跗骨窦综合征的诊断有指导价值的影像学检查方法，，为临床诊断提供更为可靠依据。 材料与方法 根据Brown早期提出的诊断标准，收集2010年2月至2011年2月在泰山医学院附属医院临床诊断为跗骨窦综合征患者68例和正常志愿者50例，所有病例均先行普通X线检查，明确足踝部骨质有无明显骨折，然后行CT和MRI检查，然后运用CT后处理技术重建出跗骨窦的立体解剖结构及韧带最大走行层面，分别测出跗骨窦的容积及韧带的各径线的数值；在不同检查方法上观察跗骨窦内各种组织的变化，并进行统计学分析；观察跗骨窦及其周围软组织和骨组织的MRI表现；在CT、MRI图像上对照分析跗骨窦综合征患者与正常志愿者的跗骨窦区的影像表现；分析跗骨窦综合征患者跗骨窦区的CT、MRI图像各自的特征，寻找最佳的影像学检查方法。 结果 (1)68例临床诊断为跗骨窦综合征患者在MRI图像上出现跗骨窦周围软组织信号异常的有58例，其中韧带损伤程度包括：Ⅰ°轻微韧带损伤（32例）；Ⅱ°韧带不完全断裂（18例）；Ⅲ°韧带完全撕裂（3例）；而正常志愿者组未发现在跗骨窦区出现软组织异常信号。（2）68例临床诊断为跗骨窦综合征患者在CT图像上显示跗骨窦区骨质有异常41例，包括陈旧性骨折X例，骨关节退行性表现X例，而正常志愿者组仅有5例，（3）跗骨窦综合征患者组磁共振图像上显示软组织较CT图像清晰，某些退行性表现如关节下囊变较清晰；在CT图像上骨组织显示较软组织显示清晰。(4)跗骨窦综合征的患者有32例患者的跗骨窦容积变小，主要出现在早期跗骨窦区骨折治疗不当和老年患者关节发生退行性变。 结论 通过对患者和志愿者行矢状位、冠状位、横轴位及斜冠状位的MRI扫描及MSCT扫描的图像对比，MRI能够更好地描述跗骨窦及其周围解剖结构的改变包括韧带、正常脂肪组织等改变，而CT能更好的描述骨质的情况；多层螺旋CT的3D重建技术能直观地显示足踝部的解剖位置关系。
[Abstract]:Objective to observe and analyze the imaging features of ankle joint X-ray, MSCT and MRI in patients with tarsal sinus syndrome and normal volunteers, and to explore a valuable imaging method for the diagnosis of tarsal sinus syndrome. It provides a more reliable basis for clinical diagnosis. Materials and methods according to the early diagnostic criteria of Brown, 68 patients with tarsal sinus syndrome and 50 normal volunteers were clinically diagnosed as tarsal sinus syndrome in the affiliated Hospital of Taishan Medical College from February 2010 to February 2011. All cases were examined by general X-ray to determine whether there were obvious fractures of foot and ankle, then CT and MRI were performed, and then the stereoscopic anatomical structure of tarsal sinus and the maximum walking plane of ligaments were reconstructed by CT post-processing technique. The volume of tarsal sinus and the diameter of ligament were measured respectively. The changes of various tissues in tarsal sinus were observed and analyzed statistically, and the MRI findings of tarsal sinus and its surrounding soft tissue and bone tissue were observed. The imaging features of tarsal sinus region in patients with tarsal sinus syndrome and normal volunteers were compared and analyzed on CT,MRI images, and the characteristics of CT,MRI images in tarsal sinus region in patients with tarsal sinus syndrome were analyzed in order to find the best imaging method. Results (1) there were 58 cases of abnormal soft tissue signal around tarsal sinus on MRI images in 68 patients with tarsal sinus syndrome. The degree of ligament injury included: I 掳slight ligament injury (32 cases); Incomplete rupture of 鈪
