For the difference between MRI 1.5T and 3.0T, these two values indicate the difference in the field strength of MRI, because the grade of MRI is distinguished by the field strength, divided into high field and low field NMR. High-field MRI generally refers to superconducting MRI greater than 1.0T, while low-field MRI generally refers to permanent magnet MRI less than 1.0T, and also individual superconducting MRI less than 1.0T. At present, the standard MRI used in major hospitals is generally MRI 1.5T or 3.0T. For the difference between 1.5T and 3.0T, the 3.0T image is more delicate, and 3.0T MRI can examine the breast as well as small organs of women, and the examination is more delicate.
