title: [Computer tomographic densitometry of primary liver tumors].
abstract: The dynamic computed tomography (CT) densitometry is defined as the combination of rapid bolus injection of urographic contrast medium and timed sequential computed tomography scan permitting recognition of different patterns of enhancement. The results of this method on fifty patients with histologically proofed hepatic tumors (focal nodular hyperplasia n = 12, cavernous hemangioma n = 13, liver cell carcinoma in cirrhotic liver n = 10, primary liver cell carcinoma n = 6, bile duct carcinoma n = 4, others n = 5) are demonstrated. CT-densitometry offers valuable aid for the differential diagnosis of focal liver lesions, i.e. cavernous hemangioma, focal nodular hyperplasia of the liver.
