[Gray-scale-sonography of gallbladder and bileducts, especially in case of a negative cholecystoradiogram (author's transl)].
The importance of ultrasonography (gray-scale-B-scan sonography) in cases with gallbladder and bileduct disease is reviewed, especially in patients with non visualization of the gallbladder. Major emphasis is put on the differential diagnosis of gallbladder stones and exophytic intraluminal tumors of the gallbladder. The efficacy of the lost shadow sign is pointed out. The sonoanatomy as well as the sonographical examination method is shortly described. In model experiments some aspects of cholecystosonography are explored.
