Ultrasonic evaluation of normal pancreatic echogenicity and its relationship to fat deposition.

Normal pancreatic ultrasound studies of 28 patients were evaluated as to pancreatic echogenicity and correlated with the morphologic appearance of the pancreas on CT to test the hypothesis that increasing pancreatic echogenicity is related to greater fat infiltration. Statistical analysis indicates that fat is a major but not the only determining factor of increasing echogenicity.
