Abstract
Planning radiation therapy is a complex process that involves the use of modern three-dimensional diagnostic techniques - computed tomography (CT) and magnetic resonance imaging (MRI). To create a treatment plan, CT is currently used, which allows to collect data of the electron density of the irradiated volume and apply them to calculate the dose distribution. However, for many tumors MRI can more accurately determine their contours. The article shows a technique for obtaining pseudo-CT images for planning radiation therapy based on MRI without the use of CT. The study included 7 patients who had a diagnosis of «medulloblastoma», underwent MRI diagnostics with identical scanning parameters and CT scan before radiation therapy. The first steps of this technique show the promise of using exclusively MRI in the radiation therapy planning.
