Magnetic resonance imaging (MRI) is an advanced medical imaging diagnostic device that uses strong magnetic fields, radio frequency pulses, and computer image reconstruction technology to perform high-resolution, non-invasive, and non-ionizing radiation imaging examinations of internal human tissues. MRI can clearly display the structure of human soft tissues and plays an important role in the early detection, accurate diagnosis, and treatment evaluation of diseases of the nervous system, bones and joints, cardiovascular system, and tumors.
