[Comparative diagnosis of focal liver changes using computed tomographic and scintigraphic methods].
The value of scintigraphic methods for the diagnosis of focal lesions of the liver (IDA, colloids, blood pool) in comparison to dynamic sequential computer tomography (CT) has been examined in this study. We found CT to be diagnostic in typical cases. For example, focal nodular hyperplasia is characterized by a rapid, strong increase and subsequent decrease after application of contrast medium (71%), whereas hemangiomas show a delayed density increase mostly at the rim (20%). In the event of deviations from the typical pattern, scintigraphic methods have to be applied which then often yield a specific diagnosis, especially in hemangiomas, focal nodular hyperplasia, and adenomas (71%). Ultrasound findings indicating the possible presence of hemangiomas or focal nodular hyperplasia should lead to scintigraphic studies prior to CT, not only for reasons of economy.
