RESUMO
The report deals with potential of present-day techniques for radiological imaging, differential diagnosis and working out of modalities of treatment for primary and metastatic hepatic tumors. Results of complex examination (ultrasound, CT, MRI, PET using fluorine -18 FDG) of patients with benign and malignant tumors are discussed. Sensitivity and specificity of each procedure have been identified to be used in diagnosis of large-size tumors.

The study involved 207 patients with large-size tumors. Results of 18FDG PET pointed to the basic factor of malignant transformation--foci of enhanced accumulation of radiological medicinal substances. Absence of ultrasound and CT-based evidence of such pathological accumulations contributed to interpretation of changes as benign ones. The effectiveness of chemotherapy was assessed by tumor metabolic response to treatment given at the time of 18FDG PET examination.
