Magnetic resonance imaging (MRI) has established itself as a fundamental diagnostic tool in modern medicine. However, its clinical implementation requires professionals and technicians to face situations requiring critical decisions, impacting both patient safety and study quality. Unlike other medical imaging modalities, MRI requires specific criteria and guidelines due to its dependence on intense electromagnetic fields, which requires prioritizing the protection of patients and occupationally exposed personnel, and obtaining high-quality diagnostic images. To date, only general MRI safety criteria have been established, underscoring the need to analyze key aspects of MRI in clinical practice and offer recommendations for its appropriate use. The main effects to be considered include: a) static magnetic field generated by the magnet, b) radiofrequency system: gradient and RF antennas, c) interactions with devices (active and passive), d) contrast agents and their considerations, e) acoustic noise generated during the exam, and f) considerations for pregnant patients. In addition, the control zones within the MRI room, the labeling of peripheral equipment, and other safety protocols are reviewed. Based on this analysis, practical recommendations are proposed to optimize safety in the clinical environment, ensuring both patient protection and diagnostic efficacy.
