[Sonographic demonstration of upper abdominal vascular structures with special reference to the ascending lumbar vein].

In a prospective study, we determined the relative frequency with which vascular upper abdominal structures could be demonstrated in a group of patients under radiological oncological treatment. Normal sono-topography is explained by means of representative illustrative material. On comparing sonography to angiography as well as to methods of nuclear medicine, it becomes evident that in all questions pertaining to angiology, sonography is of limited value as a screening method.
