CT与彩超对胰腺癌手术切除性的联合估价

目的：采用CT与彩色多普勒血流显像（CDFI）联合法对胰腺癌的可切除性进行术前瞻性评价，以确定其准确性及临床应用价值。材料与方法：1998-2000年经手术及病理证实的43例胰腺癌仅行CT检查40例，CDFI检查36例，其中33例行CT和CDFI联合检查。43例胰腺癌的可切除性评估由两名影像专家进行分析，以手术及病理结果作为标准，评价联合法的诊断价值。结果：43例胰腺癌，经手术探查和病理诊断，14例可根治切除，29例不可根治切除。CT、CDFI及CT与CDFI联合法评估的准确性分别为77.50%，77.78%，87.88%。故在评价胰腺癌可切除性方面联合法的准确性优于单一法。结论：本研究表明，在对胰腺癌可切除性的评估中，CT扫描与CDFI联合法弥补了彼此检查法不足，能够更为准确、全面地评价胰腺癌的可切除性，具有较高的价值。

Assessing the resectability of pancreatic cancer: the value of CT combined with CDFI

Objective:To evaluate the use of CT combined with color Doppler flow imaging (CDFI)in preoperative as-sessment of the resectability of pancreatic cancer and to define their accuracy and clinical value.Materials and Methods:43patients with pancreatic cancer confirmed by surgery and histopathology between1998and2000were included.40patients were given CT scans,36patients were given CDFI,in whom33patients took CDFI before CT.The resectability of 43pa-tients with pancreatic cancer was evaluated by two radiologists.CT and CDFI radiographs were correlated with surgical and histopathologic results to assess the clinical value of the combination.Results:Confirmed by surgery and histopathology,14of 43patients had resectable disease.For the other29cases,the lesion was unresectable.Using CT,CDFI and the combination of the two methods,the accuracy were77.50%,77,78%and87.88%,respectively.Therefore,the combination of two modali-ties showed superiority to CT or CDFI in assessing the resectability of pancreatic cancer.Conclusions:In assessing of re-sectability of pancreatic cancer,the combination of CT and CDFI played a complemental role to each other.The combination can further improve accuracy of assessment and have better clinical value.
