Radiologists' recommendations were generally followed for important incidental findings. These recommendations can direct the most cost-efficient and effective care for incidental findings. Although some patients with incidental findings had probable benefit, others incurred morbidity or mortality. A small number of invasive procedures resulted in substantial costs in this symptomatic population. Costs averaged over the entire population were higher than have been previously reported.

Objective: to evaluate changes in systemic and cerebral hemodynamics during percutaneous electrical stimulation of the spinal cord and in combination of electrical stimulation with mechanotherapy. Methodology. The subjects underwent percutaneous electrical stimulation of the spinal cord, the duration of the session was 5 minutes. Mechanotherapy was performed using a treadmill. The subjects performed walking at a power of 25W. for 5 minutes. Hemodynamics was evaluated before and after the electrical stimulation session, as well as before and after the mechanical therapy session on the track in combination with percutaneous electrical stimulation of the spinal cord. To study systemic and regional hemodynamics, a rheograph-polyanalyzer "REAN-POLY" was used. Results. Electrical stimulation of the spinal cord does not lead to significant changes in systemic and cerebral hemodynamics. Percutaneous electrical stimulation of the spinal cord in combination with physical exertion leads to reactive changes in systemic hemodynamics, increased blood filling and venous outflow, against the background of a decrease in peripheral resistance of cerebral vessels. Key words: electrostimulation, percutaneous electrostimulation, mechanotherapy, systemic hemodynamics, regional hemodynamics.

The characteristic fuel cycle (FC) schemes for fusion and hybrid (fusion-fission) reactors are considered. The FC structures of the facilities that are under construction and of newly designed ones are analyzed. The FC architecture general features and specific ones of each facility are highlighted. Two simplified FC schemes are proposed, and a computer program for solving a system of differential equations and simulating the accumulation of fusion fuel component (tritium) in FC systems in a steady-state operation mode of the facilities has been developed. The obtained results are compared with published calculations for the DEMO, SABR, and DEMO-FNS facilities. The computer codes used for numerical simulation of the fusion reactor FCs are reviewed; a high relevance of the problem being solved is shown, and proposals for further sophistication of the developed model are formulated.
