摘要

胰藏(the pancreas)是藏於後腹膜(retroperitomun)之後橫跨於第二腰椎之上，在臨床上的檢查不容易，最近的腹部超音波(U. S.) 及自內視鏡逆行性胰膽攝影術(E. R. C. P.) 及血管造影的進步，雖然解決部份的困難，但仍然不能窺其全貌。自Body C. T. 發展出來之後，因有高度解像力(high resolution)，能將腹內器官描出來。本文是以本院64例做過腹部C. T. 來作回顧性的研究(retrospective study)與分析。

並列摘要

The pancreas hides in the retroperitoneum and across the 2nd. lumbar vertebra. It is difficult to approach clinically. Since 1972, the body C. T. has developed perfectly and the diagnosis of pancreatic lesion becomes possible. Now, we collect 64 cases of pancreatic C. T. Scan for retrospective study and analysis. We have measured the width of normal pancreas which divides into pancreatic head, body & tail. Pancreatic and vertebral body ratio which was mentioned by Dr. J. HAAGA was adopted by us. The value of measurement of the width of pancreas is 0.7 to 1.0 in the head, 0.6 to 0.8 in the body and 0.4 to 0.6 in the tail. If the P:V ratio is larger than 1.0 we will suspect some lesion in this area. The contagious vessels such as I.V.C., S.M.A. or aorta are the important marks to read the pancreatic C.T. Scan. The pancreatic scan can be influenced by some factors. Such as 1. Thin patient can not obtain a good scan because the fat plane in the pancreas and contagious organs are disappear. 2. fecal material & gas in the G．I tract make artifact. 3. the enlarged lumph nodes which are metastatic to pancreatic area are difficult to different from the pancreatic lesion. This is our early experience to read pancreatic C. T. scan. Then, we will collect more cases to study in this field.
