多层螺旋CT对评价胰腺癌可切除性的作用

目的 探讨多层螺旋CT评价胰腺癌的可切除性，并与手术比较。方法 使用TOSHIBA Aquilion16层螺旋CT，对67例临床胰腺癌患者行动态增强CT扫描，判断胰腺病变大小，评价及判别胰周血管是否受累，观察肝脏及腹膜后淋巴结是否转移，判别胰腺癌的影像学可切除性，结合手术及病理结果，进行统计学分析。结果 CT增强扫描判断胰腺癌可切除性的敏感性72．72％，特异性98．21％。通过卡方检验，x^2=1．000，P〉0．05，胰腺癌可切除性的术前CT判断与外科手术判断在统计学上没有差异。结论 CT判断胰腺癌可切除性对选择手术方式具有前瞻性指导意义。

Role of multislice spiral CT for assessing the reseclability of pancreatic carcinoma

Objective To compare the sensitivity between multi-slice spiral computed tomography（MSCT） and surgery for assessing the resectability of pancreatic carcinoma. Methods Sixty-seven patients with clinically proved pancreatic carcinoma underwent MSCT scans of the upper abdomen with dynamic contrast enhancement. CT scans in all patients were performed by using TOSHIBA Aquilion 16- detector row CT scanner. On dynamic CT images, the reseetability of pancreatic carcinoma was assessed according to following CT findings which comprised the size of eareinous lesions, whether peripanereatie vessels were involved and whether metastaees of hepatic-and retroperitoneal lymphonodi were occurred. All CT data were statistically analyzed and compared with those of surgery and pathology. Results The sensitivity and specificity of dynamically enhanced CT scans for assessing the reseetability of pancreatic carcinoma were 72.72% and 98.21%, respectively. With ehi-square criterion, X^2 = 1. 000, P 〈 0. 05, the sensitivity between preoperative CT and surgery for assessing the reseetability of pancreatic carcinoma was not statistical difference. Conclusion The assessment of contrast enhanced CT for the reseetability of pancreatic carcinoma and the selection of operative modality has prospective guide significance.
