Diagnosis of extra-hepatic abnormalities on dynamic study over thoraco-abdominal region prior to hepatic imaging

Findings on 262 thoraco-abdominal dynamic studies done at the time of hepatic imaging were reviewed. Twenty-nine extra-hepatic abnormalities were diagnosed solely on the basis of these studies, including pericardial and pleural effusions and decreased perfusion to one lung. Half of these abnormalities were not suspected clinically. The dynamic study is an important part of hepatic imaging and should be performed routinely. Besides aiding in differential diagnosis of various hepatic lesions, extra-hepatic abnormalities can be discovered.
