为提高对胰腺疾病的 CT诊断水平 ,根据被证实的 5 0例胰腺癌和 40例慢性胰腺炎的 CT资料 ,对 CT征象进行观测、统计及分析。结果发现二者诊断与鉴别诊断的主要征象是 :1病变区胰腺局限或弥漫肿大与密度异常 ;2有无扩张的胆总管突然性狭窄截断与胰周大血管被包埋 ,管径增粗、癌栓、腹部淋巴结肿大、肝转移 ;3有无沿胰管走向分布的钙化与扩张的胰管 ,扩张胰管贯通病变区的情况 ;4胰腺囊肿的发生频率、部位与胰腺轮廓的关系。结果显示 :根据前述要点 ,参考其他征象 ,密切结合临床 ,CT诊断正确率达 90 %以上。
In order to improve the CT diagnosis of pancreatic diseases, the CT signs were observed, counted and analyzed according to the CT data of 50 confirmed pancreatic cancers and 40 chronic pancreatitis cases. It was found that the main signs of both diagnosis and differential diagnosis were: 1 limitations or diffuse swelling and density of the pancreas in the affected area; 2 sudden stenosis of the common bile duct with or without dilation and embedding of the large peripancreatic vessels with a thickened diameter , tumor thrombus, abdominal lymphadenopathy, liver metastasis; 3 calcified and dilated pancreatic duct distributed along the direction of pancreatic duct; dilated pancreatic duct penetrated the lesion area; 4 pancreatic cyst frequency, location and the relationship between the pancreas contour . The results showed that: According to the foregoing points, with reference to other signs, and closely combined with clinical, CT diagnosis accuracy rate of more than 90%.
