Is it true that the nuclear magnetic resonance in the hospital says that there is radiation, so please stay away as far as possible?

Magnetic resonance imaging (MRI) is a common imaging examination, which, like B-ultrasound, X-ray and CT examination, can help to examine some substantial conditions of the internal organs of the body. However, because MRI does not have radiation, most people prefer MRI when they need CT or X-ray examination, but they don't know that MRI does not have radiation, but.

the electromagnetic wave is mainly used when the nuclear magnetic resonance (MRI) is carried out, and the amount radiated by the electromagnetic wave is relative to the energy released by mobile phones and televisions at ordinary times, so there is no radiation to the body and no harm, so many people tend to check the MRI at ordinary times, which is also the advantage of MRI. In addition, the nuclear magnetic resonance * * * vibration will not be affected by the bone during the examination, and the examination results can be obtained more pertinently, and the examination results are more correct. However, although nuclear magnetic resonance vibration does not have radiation, it can be checked more accurately, but it also has some shortcomings.

Generally speaking, not everyone can perform MRI. For example, some patients who have pacemakers in their hearts or are afraid of small spaces can't perform MRI, and accidents are easy to occur during the process.

Compared with X-ray and CT examination, the price of MRI is relatively high, and it is difficult to make an appointment in advance before the examination, so it is difficult for people with poor economy to choose.

if the patient is in an emergency and is in a critical state, it is not an ideal scheme to have an MRI * * * vibration, because it takes a long time for examination, which takes about half an hour. If you choose an MRI in an emergency, it will easily delay the illness. In this case, CT or X-ray is needed to preliminarily judge the illness.

Although the images displayed by magnetic resonance imaging (MRI) in the process of examination are clear and can be examined in a targeted way, it is weak in showing some calcification, lung examination and acute bleeding.

Generally speaking, although MRI is a radiation-free examination, and the results are more accurate during the examination, patients should know that MRI is also insufficient, and they should know whether they are suitable when they need to be examined, so as to make their bodies undergo MRI examination, so as to avoid delaying their illness and causing more serious injuries due to wrong selection.
