目的:了解超声、螺旋CT对预测胰腺癌手术可切除性及不可切除性的准确性。方法:对48例行手术治疗的胰腺癌病人,术前作超声及螺旋CT扫描检查,将影像所反映对癌肿可切除性及不可切除因素,与术中所见作对比分析。结果:螺旋CT增强薄层扫描对癌肿不可切除性预测的符合率为97.7%,超声为90.7%;两者对胰腺癌可切除性预测的准确性分别为83.3%和55.6%。结论:超声、螺旋CT增强扫描对胰腺癌的不可切除性预测有较高的准确性,对可切除的预测也有一定的参考价值。
Objective: To understand the accuracy of ultrasound and spiral CT in predicting the resectability and unresectability of pancreatic cancer. Methods: For 48 pancreatic cancer patients who underwent surgery, preoperative ultrasound and spiral CT scans were performed. The images were analyzed for the resectable and unresectable factors of cancer and compared with those seen during the operation. RESULTS: The coincidence rate of spiral CT enhanced thin-slice scan for predicting the unresectability of cancer was 97.7%, and ultrasound was 90.7%. The accuracy of predicting resectable pancreatic cancer was 83.3% and 55.6%, respectively. Conclusion: Ultrasound and spiral CT enhanced scans have high accuracy in the prediction of unresectable pancreatic cancer, and have certain reference value for resectable prediction.
