[The role of positron emission tomography with C18-Fluorodeoxyglucose in clinical oncology].
The study was concerned with evaluation of the diagnostic potential of positron emission tomography (PET) with 18-FDG in clinical oncology and elucidation of its role in assessing therapy effectiveness. The Ecat Exact 47 and Ecat Exat HR+ (Siemens) insatllations were used to examine 674 patients, with Whole Body protocol used in 585. PET with 18-FDG proved highly effective in diagnosing malignancies of the breast, lung, liver, pancreas, testis, brain and lymphoma as well as evaluating the efficacy of therapy.
Brain Neoplasms↗
[Role of current MRI technology in the diagnosis of pancreatic tumors].
The Magnetom Vision unit (Siemens) with 1.5 T magnetic field and a Body surface coil was used to examine 87 patients with pancreatic tumors, adenocarcinoma--56, cystadenoma--3, and chronic pancreatitis--28. Magnetic resonance cholangiopancreatography (87), dynamic contrast-enhanced MRI (56) and MR angiography of the abdominal cavity (21) were used in conjunction with the paramagnetic drugs Magnevist (Shearing) or Omniscan (Nikomed). All necessary data for diagnosis and planning of surgical treatment of pancreatic tumors were obtained during a single examination due to complex use of present-day MRI techniques.

[Ultrasound diagnosis of angiopathy in antitumor therapy].
The ultrasound characteristics of arterial walls were assessed in 78 young and middle-aged male (42) and female (36) cancer patients (mean age 36 +/- 0.9) receiving radiation and/or polychemotherapy. The study was specifically concerned with quantitative and qualitative changes in the "intima-media" complex and the vasoactive dysfunction of the endothelium. We established the ultrasound characteristics of arterial walls, in particular, the damage done to the complex in the arteries in exposed sites, and angiopathies as a systemic manifestation of vasoactive dysfunction (polychemotherapy) or the combined effect on the vascular wall radiopolychemotherapy, vis-a-vis each therapeutic modality, separately and in combination.

[The role radiography in assessing the stage of renal cancer].
The investigation included 421 cases of renal cell carcinoma with metastases of different localization. Tumor advancement was assessed by application of general-view imaging, X-ray, computed and magnetic resonance tomography, ultrasound and osteoscintigraphy. Alterations in the lung were registered in 271 patients (64.4%); metastases into bones--244 (57.9%). Tumor dissemination to retroperitoneal lymph nodes was detected in 166, liver--96 and the brain--6 patients.
