RESUMEN
Introduction into clinical practice of combined positron emission technology and computer tomography (PET/CT) allows in one study to identify structural and functional abnormalities. The study involves 32 patients who underwent PET/CT with "C-choline, including 5 patients with prostate cancer (PC), 3--with chronic prostatitis and 24--with biochemical PC recurrence. PET/CT with 11C-choline has a high diagnostic efficacy in detection of local recurrence and PC metastases in patients with biochemical PC recurrence. The results of visual analysis do not permit to distinguish PC from benign prostate diseases.

The paper describes 12 years' experience in using positron emission tomography (PET) at the Russian Research Center of Radiology and Surgical Technologies to detect cancer, cardiac, and psychoneurological diseases, to make their differential diagnosis, and to evaluate the efficiency of their treatment. It shows the capacities of PET using various radiopharmaceutical agents in a broad spectrum of the above abnormalities and defines prospects for further development of the technique.
