[Sonographic diagnosis of a calculus in the obstructed pancreatic duct]. / Sonographische Diagnostik eines Konkrementes im gestauten Pankreasgang.

It is shown by means of a case report on a calculus in the dilated pancreatic duct, that abnormalities in small structures such as the pancreatic duct can be revealed by ultrasound, using current gray-scale instrumentation.

[Craniocaudad extension of the head of the pancreas]. / Die kraniokaudale Ausdehnung des Pankreaskopfes.

In 106 patients without pancreatic disease subjected to ultrasound examination the craniocaudad dimension of the pancreatic head was determined. The mean craniocaudad echographic size of the pancreatic head was 5.9 cm in female and 6.2 cm in male individuals. The knowledge of the craniocaudad dimension of the pancreatic head may be useful to avoid misinterpretation of lymph node enlargement in the region of the pancreatic head.

[Sonographic artifacts of round reflectors]. / Sonographische Artefakte an rundlichen Reflektoren.

The appearance of the proximal curved edge artifact using linear-array systems is demonstrated in five cases. Furthermore simulation of this artifact was achieved in a waterbath. A physical explanation of this phenomenon is discussed.
