Transarterial radio-embolization (TARE) using yttrium-90 microspheres is a promising method based on the brachytherapeutic effect of radionuclide with beta-minus decay dissolved in solid microparticles applied directly to tumor-supplying arteries. This treatment is complex, as well as logistically and technically extremely demanding and must be planned in detail. The visualization of the vascular supply of the liver and the possible parasitic supply of the tumor is essential not only for indication of the procedure and correct identification of the arteries to which the microspheres will be applied, but also for prevention of non-target deposition of radioactive material. This review addresses the use of computed tomographic angiography in the preparatory phase of TARE.
