The differences between MRI 3.0 and 1.5 are mainly as follows: 1. The intensity of magnetic induction is different. 2. 3.0 has a higher resolution than 1.5. For example, if cranial nerve examination is needed, 3.0 can clearly show the structure of nerve fiber bundles on the image, while 1.5 cannot do so, for example, to show the structure of blood vessels, 3.0 can show more fine branches of blood vessels. 3. to change together. Therefore, 3.0 and 1.5 MRI are two almost completely different systems. In clinical practice, depending on the needs of different diseases, some need to use 3.0, while conventional disease diagnosis only needs 1.5.
