Is it harmful to have a head MRI done in people? Whether it affects the lifespan

MRI generally feels uncomfortable, mainly due to noise and psychological factors. In fact, MRI is much safer than CT and X-ray! Many patients are nervous and scared in that closed cavity when they go up for a check-up, and some patients jump in fear with a loud knocking sound and vibration at the beginning of the scan!

There are also people who shake involuntarily. Actually, it's not necessary at all!

Generally, high-field superconducting magnetic resonance only provides headphones, and the noise of low-field machines can be tolerated without headphones.

Before the examination, be careful not to wear ferromagnetic materials on your body, such as metal jewelry, mobile phone magnetic cards, watches, etc.

Sometimes you can't see clearly with a conventional non-contrast scan, you may need to inject an MRI contrast agent and redo the enhanced scan, but it's all safe, don't worry! Whether it is the reliability or accuracy of diagnosis, magnetic resonance imaging is currently the most reliable method for routine examination!

As for the examination time, it generally takes about 15 minutes for the low-field machine in a small hospital, and the superconducting machine in a large hospital is 3-5 minutes to scan!

As for vomiting and confusion, it was a very, very small number and not necessarily caused by the MRI itself!

RF RF field heating mainly refers to RF RF deposition, called SAR, which must be strictly controlled when the magnetic resonance manufacturer leaves the factory, and there will definitely be no problem, otherwise there will be a problem!

There is no harm. Magnetic resonance imaging (MRI) has become a common imaging examination method, and magnetic resonance imaging, as a new imaging examination technology, will not have an impact on human health. Since MRI is magnetic field imaging and is not radioactive, it is harmless to humans.

Although MRI is unique in screening for early lesions, there are limitations to any examination, for example, some patients are not suitable for MRI, so do not over-examine. Any patient should follow the doctor's instructions for the examination, do not think that the more expensive the imaging test, the better, and only the test that is suitable for them is the best.

Frequent nuclear resonance will disrupt the endocrine, and will also cause some chronic diseases and affect the growth of white blood cells, especially leukemia. It will affect the stomach and intestines, and the body will become very weak.

Doing "nuclear magnetic resonance" often has some radiation effect on the human body, don't do it often, it is easy to hurt people's **, hurt **surface, and harmful to **.

There are harms, nuclear radiation is more serious, so it will hurt **, affect attention, memory, cranial nerves, and in severe cases, it will lead to cancer.
