MRI 1.5 and 3.0 represent field strengths of different intensities, 1.5T and 3.0T respectively, where 3.0T is stronger than 1.5T MRI magnetic field strength, so the resolution will be higher. In the various tissues and organs, the display of tissue structure to be more clear, to provide more information. However, in general, the field strength of 1.5T is enough for common diseases, and 3.0T MRI is used to check some specific parts, such as three-dimensional volumetric imaging of the abdomen or the examination of fine tissue structure, and 3.0T MRI is more expensive and noisy, which will cause some damage to the human body.
