DIAGNOSTIC-ACCURACY OF SCINTIGRAPHIC METHODS IN THE DIFFERENTIAL-DIAGNOSIS OF FOCAL LIVER-LESIONS

In a retrospective study of 160 patients who were examined within 12 months, we analysed the diagnostic value of scintigraphic techniques in the differential diagnosis of solid focal liver lesions. Haemangiomas were found in 77 patients. Bloodpool scintigraphy was true-positive in 66 (sensitivity 85%); for lesions greater than 2 cm in diameter, sensitivity increased to 94%. Metastases of CEA-expressing tumors were found in 42 patients, anti-CEA-immunoscintigraphy was true-positive in 33 patients (sensitivity 78:5%). Focal nodulary hyperplasia was found in 3 patients, adenomas in 6 patients. In the remaining 32 patients we saw 4 hepatocellular carcinomas, 28 metastases from lung and breast cancer, 2 echinococcus cysts and 1 choledochus cyst.
