It is difficult to examine the pancreas by routine roentgenographic methods, radioisotopic scanning and angiography. The ultrasonography has proved to be an useful tool in the evaluation of pancreatic diseases. Determination of the normal size and contour of the pancreas is important. We performed ultrasonography in 89 subjects with normal pancreas and the results were reviewed. 1 Successful ultrasonograms of normal pancreas were obtained in 84 among 89 subjects examined, being 94.4po of success rate The shapes of pancreas were dumhhell shape in 47 of 84 cases(55. 9%), sausage shape in (29.8%) tadpole shape in 11(13. 1%), and reversed tadpole shape in 1 case. 3.The pancreatic head was 1.8+-0.38cm in the mean thickness(range: l. 0-2. 9cm), the neck l. 1+- 0. 41 cm (range: 0. 4-2. 0 cm), and the body 1. 8+-0. 37 cm (range: l. 0-2. 6 cm).
