【摘要】 目的　探讨胰腺癌的CT表现与临床关系及对手术的指导意义。方法　回顾分析了 5 0例经病理证实的胰腺癌 ,利用CT的直接、间接征象以及临床表现 ,评估手术价值 ,分析检查技术的应用与病变检出率的关系。结果　胰头癌 36例 ,占 76 %。胰体癌 12例 ,占 2 4 %。胰尾癌 2例 ,占 4 %。病灶直径在 2 .7～ 15cm之间 ,直径小于 3cm的 18例 ,其中囊腺癌 6例。 5 0例术前评估手术切除 2 0例 ,可能切除 12例 ,实际切除 15例 ,占评估切除率的 4 6 .9%。结论　胰腺增大 ,钩突变形及密度不均为胰腺癌的直接征象 ,当发现胆总管及主胰管扩张 ,应高度怀疑胰腺癌存在的可能 ;CT增强扫描评价胰腺癌对周围血管受侵犯及转移具有相当的正确性。胰周器官及血管的改变对选择手术有一定指导意义。更多还原

【Abstract】 Objective To explore the value of CT examination in treating pancreatic carcinoma.Methods The relationship of CT examination and the detection rates of 50 cases of CT examination and the detection rates of 50 cases of pancreatic carcinoma confirmed pathologically was analyzed through restrospectively studying the CT expressions and clinical symptoms.Results Among the 50 cases of pancreatic cancers,36(76%) occurred in the head of pancrea,12 cases (24%) in its body and 2 case (4%) in its tail.The size of tumors ranged from 2.7～15cm in diameter.18 cases had their diameters shorter than 3cm,of whilch 6 cases belonged to cystadenocarcioma.Preoperative evaluation suggested that 20 cases should recive resection,and 12 cased might receive removal.15 cases received removal in hospital,about 46.9% of the whole cases evaluated preoperatively.Conclusion Enlargement of pancreas and their inhomogeneous density and irregular contour of the uncinate process are the direct clinical signs of pancreatic carcinoma.Dilated bile duct and pancreatic duct may also suggest the occurrence of pancreatic carcinoma.CT contrast scanning can accurately show the eroded blood vessels.The changes in organs and blood vessels around pancreas have somewhat direction for the selections of operations.更多还原
