[A comparison of static liver scintigrams in supine and erect patients (author's transl)]

The study compares the results of liver scintigrams performed on patients whilst standing and lying down. One hundred and ten patients were examined and in 12 cases, examination in the erect position lead to important diagnostic information. By changing position, it is possible to exclude apparently abnormal defects of uptake; on other occasions the changed configuration of the liver permits the recognition of genuine lesions. Additional examinations on the erect patient help to reduce the incidence of false positive and false negative findings during liver scintigraphy.
