磁共振成像（MagneticResonanceImage。MRI）是指机体内的原子核在一定强度磁场作用下，通过无线电射频脉冲使其发生核磁共振，进而对核磁共振所产生的信号进行计算机处理，然后由显示系统显示出机体组织器官的影像。由于氢原子核仅由质子构成，同时在人体中含量最大，因此目前
Magnetic resonance imaging (MagneticResonanceImage.MRI) refers to the body of the nucleus in a certain intensity of magnetic field, through radio frequency pulse to make it nuclear magnetic resonance, and then generated by the NMR signal processing computer, and then by the display system shows the body Tissue and organ images. At present, hydrogen nuclei consist of only protons and are present in the human body at the same time
