目的 用电子束CT对胰头癌的可切除性进行术前评价 ,以确定电子束CT对胰头癌分期诊断的应用价值。方法 对 5 7例胰头癌行动、静脉双期扫描或实质期扫描并三维成像 ,术前评价其可切除性 ,并与手术中发现相比较。结果 本组 5 7例胰头癌均被手术探查证实。可根治切除 2 1例 ,行动、静脉双期扫描 32例 ,行实质期扫描并三维成像 2 5例。电子束CT判断胰头癌不能切除的准确率为 94%、可切除的准确率为 71% ,两种扫描方式无差别。结论 电子束CT能较为准确、全面地评价胰头癌的可切除性 ,具有较高的临床应用价值。
Objective To preoperatively evaluate the resectability of pancreatic head cancer with electron beam computed tomography (CT) to determine the value of electron beam computed tomography in the diagnosis of pancreatic cancer. Methods Fifty-seven patients with pancreatic cancer of the pancreas were treated with two-phase or two-phase real-time scanning and three-dimensional imaging. The resectability was evaluated preoperatively and compared with the findings of surgery. Results The group of 57 cases of pancreatic cancer were confirmed by surgical exploration. In 21 cases, radical resection was performed in 32 cases, double-action and venous in 32 cases, real-time scanning and 25-dimensional imaging in 23 cases. Electron beam CT to determine the accuracy of pancreatic cancer can not be removed 94% accuracy, resectability of 71%, no difference between the two scanning methods. Conclusion Electron beam computed tomography (CT) can evaluate the resectability of pancreatic head cancer more accurately and comprehensively and has higher clinical value.
