The report introduces two imaging modalities which are MRI and CT. Principles of imaging will be introduced respectively. MRI is based on nuclear magnetic resonance (NMR) while CT is based on pulse-echo reflection of X-ray. Additionally, the development history of MRI is included such as some experiments performed by scientists who contributed a lot in the investigation of MRI. Furthermore, comparisons are made between MRI and CT in cerebral infarction and femoral head necrosis. Advantages and disadvantages are stated after comparison. Additionally, MRI can be widely utilized in chemical manufacture industry and mining detection because magnetic field can be easily established and it can find out internal structure which is essential in supervision.
