概要

Computed tomograms (CT) were studied in 59 control subjects, 38 patients with chronic pancreatitis, 10 patients with pancreatic tumor and 2 patients with pancreatic cyst, a total of 109 patients.The ratio of the largest width of the pancreas to the width of th vertabral body (P/V) was 0.60± 0.10 in the head, 0.55±0.08 in the body and 0.54±0.09 in the tail of the normal pancreas (mean±SD), which appeared as a rod-like organ with homogenous density. The diameter of the pancreatic tumor permitting confirmation by P/V>0.80 appears to be above 3.0cm. In small or diffuse pancreatic cancer, P/V is normal, and unbalanced shape of the pancreas and inhomogenous density of the tumor represent important findings.In cancer of the head of the pancreas, cholestatic findings such as the dilated gallbladder should be emphasied. In malignant pancreatic cyst, unlkie the benign cyst, the inside of the cyst is irregularand the internal density is inhomoggenous.In chronic pancreatitis, CT is useful for detecting pancreatic calcification. CT is capable ofconfirming stones in the pancreas and permits a clearer demonstration of the shape and distribution of the stone than simple X-ray film of the abdomen.
