Conventional rdadiology of the pancreas are too often unsatisfactory. It is well known that the whole body CT is very useful in identifying retroperitoneal pathology. The authors intended to present normal pancreatic morphology and data for preparation of basis for interpretation of abnormalities. We results were as follows ; 1. There were 36 male and 24 female patients, and their ages ranged from 7 to 78 years. 2. 1) The organs adjacent pancreas were stomach, inferior vena cava, duodenum, acudate lobe of the liver left kidndy, left adrenal gland, superior mesenteric vessels, spleen 2) In 19 patients, pancreatic tail at the level of left kidney in the transverse plane, it was either ventral in 13 (68%), ventromedial in 2 (19%), ventrolateral in 4(21%) to left kidney, in the other 41 patients, it was cranial to the upper pole of left kidney, ventral in 25(61%), ventromedial in 1(2%), ventrolateral in 15(37%). 3) Pancreatic tail was cranial to the pancreatic body, 3cm cranial in 2(4%), 2-3cm in 5(8%), 1-2cm in 6(10%), less than 1cm in 11(18%). In the other, caudal in 3(5%). 4) Pnacreatic tail was cranial to the level of the splenic hilum in 36(60%), 0-2cm caudal in 24(40%). 3. Pancreatic shape was uniform tapering form in 37(62%), lobulated form in 23(38%). 4. Pancreatic orientation was horizontal in 13(22%), vertical 56(76%), S-shaped in 1(2%). 5. Pancreatic margin was smooth in 22(37%), lobulated in 38(63%). 6. In most patients, pancreas was uniform in density. 7. Pancreatic size was 0.5$pm$0.1 in measurement ratio of the head in 48(80%), 0.4 $pm$0.1 of the body in 49(88%), 0.5$pm$0.1 of the tail in 47(78%).
