目的 探讨螺旋CT双期薄层增强扫描对胰头癌可切除性的评估价值。方法 回顾性分析 2 4例经螺旋CT双期薄层增强扫描胰头癌的CT表现 ,观察肿块对邻近器官或组织侵犯情况 ,以及有无远处器官和淋巴结转移 ,据此判断肿块能否切除 ,并将其结果与手术病理结果相对照。结果 螺旋CT判断胰头癌可切除的敏感性为 90 .9% ,特异性为 84.6 % ,阳性预测值为 83 .3 % ,阴性预测值为 91.7% ,准确性为 87.5 %。结论 螺旋CT双期薄层增强扫描判断胰头癌可切除性的价值较高 ,对外科医生选择最佳治疗方案有较大的帮助
Objective To evaluate the value of dual-phase thin-slice spiral CT in assessing the resectability of pancreatic head cancer. Methods The CT findings of 24 patients with pancreatic head cancer were retrospectively analyzed by spiral CT double-slice thin-slice scanning. The invasion of adjacent organs or tissues was observed and the distant organs and lymph node metastases were observed. , And the results and surgical pathology results contrast. Results The sensitivity, specificity and accuracy of helical CT were 90.9%, 84.6%, 83.3%, 91.7%, and 87.5% respectively. Conclusion The value of dual-phase thin-slice spiral CT in determining the resectability of pancreatic head cancer is of great value to surgeons in choosing the best treatment plan
