The main differences between MRI 1.5T and 3.0T are the different strengths of the magnetic field sensitivity, the different resolutions, and the different resonance frequencies. MRI 1.5T and 3.0T belong to two completely different systems, the 3.0T system has a greater intensity of magnetic field sensitivity, and the resolution is significantly higher than the 1.5T system. MRI due to changes in magnetic field strength, the resonance frequency changes of the two systems will also be different, 3.0T compared to 1.5T in the examination of various tissues and organs in the display to be more clear, can also provide more information. In addition, the cost of MRI examination of 3.0T system will be relatively higher, and the noise during the examination will be louder, which may cause certain damages to the human body. Therefore, when doing the MRI examination, you should choose the intensity of the MRI reasonably according to your own actual situation and under the doctor’s advice.
