[Ultrasonography of the pancreas. Diagnostic problems and findings in cases of solid pancreatic masses (author's transl)].

By using rigourous examination techniques and interpretive criteria, ultrasonography of the pancreas can, in many cases, confirm the etiological diagnosis of solid pancreatic masses. Factors influencing diagnosis are the volume and shape of the pancreas, the ultrasound structure, the attenuation of ultrasounds, the outline of the pancreas, and the effect on neighbouring structures. The association of signs is often characteristic and can differentiate benign from malignant masses.
