First of all, I would like to popularize why we need to take injections. There are two types of MRI examination, one is called plain scanning, which is directly lying on the body for scanning; the other is called enhancement, which is called enhancement scanning, which is to enhance the lesions found in the plain scanning to look at the blood supply as well as enhancement, i.e., injections are only needed for the enhancement scanning. Because of the breast lesions, the MRI must have found some problems, rarely take the MRI so expensive examination method for the initial screening, so the routine breast MRI need to be injected for enhancement scanning, it is the same method of injection and ordinary MRI enhancement scanning, in the back of the hand, this do not have to worry about, the experienced nurses will give you a good this step.
