However, the strong magnetic fields and radiofrequency pulses used in MRI can pose potential safety risks to patients and healthcare workers. This review aims to provide an overview of the physics behind MRI safety, including static magnetic fields, radiofrequency fields, and gradient magnetic fields. Additionally, it discusses safety considerations, such as the risks associated with ferromagnetic objects, thermal effects, acoustic noise, and the potential for biological effects. Finally, this review highlights the importance of adherence to safety guidelines and the continuous development of safety protocols to ensure safe MRI practice.
