| 摘 要： | 仅有约20％的胰腺癌患者在就诊时尚有手术切除的机会。多层螺旋CT对于胰腺癌术前不可切除的阳性预测值较高,而可以切除的阴性预测值相对较低,主要是因为未发现小的肝脏或腹膜转移以及未发现主要血管受侵。注射对比剂后增强扫描的胰腺期及肝脏期对于术前分期及可切除性评价至关重要。

| Abstract: | Only about 20% patients with pancreatic cancer are considered surgically resectable at the time of diagnosis. Multi-slice helical CT has an excellent positive predictive value in determining tumor unresectability, but has a relatively low negative predictive value in determining tumor resectability due to undetection of liver and peritoneal metastases and major vascular involvement. It is essential of pancreatic parenchymal phase and hepatic phase of contrast-enhanced CT for assessing tumor stage and resectability before surgery. |
