MSCT三维成像在胆管囊肿诊断中的临床应用

Application of multi-slice CT three-dimensional imaging in Choledochal cyst

目的探讨MSCT三维成像在胆管囊肿诊断及临床治疗中的应用价值。方法对42例胆管囊肿的患者行CT检查,所获图像传输至影像工作站进行CT三维重建。结果螺旋CT平扫图像及三维重建图像对42例胆管囊肿的病例均做出了准确诊断。按照Todani分类法,Ⅰ型16例,Ⅳ型24例,Ⅴ型2例。CT表现为不同部位的胆管囊状扩张,边界清楚,边缘光滑,增强扫描后囊壁强化,囊内容物不强化,周围结构不同程度受推移。胆管囊肿合并结石4例,合并感染1例,合并胆囊炎14例、合并胆囊结石5例,合并胆管癌1例,合并胰腺炎1例。结论 MSCT三维成像对胆管囊肿的影像诊断具有特征性,有利于本病的确诊和分型。

Objective To explore the application value of multi-slice spiral computer tomography （CT）three-dimensional （3D） imaging in the diagnosis and clinical treatment of Choledochal cyst. Methods CT scan was used for 42 patients with bile duct cyst, the images from the CT scan were transmitted to the workstation for 3D CT reconstruction. Results 42 cases of choledochal cyst were accurately diagnosed through the spiral CT scan images and 3D reconstruction images. According to Todani classification, there were 16 cases of type I , 24 cases of type 11/-, and 2 cases of type V. CT showed different parts of the bile duct cystic dilatation, and its boundary was clear, edge was smooth. On enhanced scanning, the cyst wall was enhanced, the cystic content was not, the structure around the bile duct cyst was pushed in various degrees. 4 eases of bile duct cyst complicated with stones, 1 case complicated with infection, 14 cases complicated with cholecysti- tis, 5 cases complicated with gallbladder stones, 1 ease was associated With bile duct carcinoma, and 1 ease was associated with acute pancreatitis. Conclusion The multi-slice spiral CT 3D imaging will be characteristic in imaging diagnosis of bile duet cyst, which is favorable to the disease diagnosis and classification, and it can guide the clinical treatment.
