Abstract
Purpose: To evaluate the rationale and feasibility of expanding the application of magnetic resonance imaging in the clinical practice of the Radiology Center at the FMBC.

Material and methods: Radiation exposure doses were analyzed among workers employed in industries with sources of ionizing radiation during computed tomography (CT) examinations. The study included 658 patients aged 23 to 65 years (496 men and 162 women) who underwent CT between 2020 and 2024 at the FMBC. A comparative assessment of the diagnostic capabilities of CT and magnetic resonance imaging (MRI) was conducted based on a review of current Russian methodological guidelines for key anatomical regions of the body and on examples of three clinical cases from own experience.

Results: The highest radiation doses are observed during contrast-enhanced CT of combined anatomical areas, reaching 23.75 to 25.15 mSv per examination. A review of national methodological guidelines on radiological diagnostics and the results of CT and MRI scans in the presented clinical cases revealed opportunities for expanding MRI application within the practice of the Radiology Center, particularly for specific pathologies and anatomical regions while reducing the radiation load on patients.

Conclusion: Need for more active use of MRI is primarily based on the need to reduce individual radiation exposure during diagnostic examinations, which is particularly relevant for personnel occupationally exposed to ionizing radiation. For several anatomical regions, MRI demonstrates diagnostic accuracy comparable to CT and can be effectively used for follow-up without repeated radiation exposure. This is particularly important for reducing cumulative doses among workers employed in industries with sources of ionizing radiation during CT. These findings support the integration of MRI as a dose-sparing diagnostic alternative in the clinical workflow of the Radiology Center at the FMBC.
