Focal nodular hyperplasia of the liver as established by 99mTc sulfur colloid and HIDA scintigraphy.

Abstract
Three cases of focal nodular hyperplasia of the liver are reported, presumably associated with the long-term use of oral contraceptives. Special reference is made to hepatobiliary scintigraphy with 99mTc diethyl-IDA, and the cause of the observed findings is discussed.
