Why don’t doctors recommend an MRI scan? Doctors tell the truth, early knowledge will benefit

Due to the continuous development of modern society, people are gradually opening their minds, and many people pay more attention to their own health problems, and even go to the hospital for regular check-ups.

Even so, many people cannot avoid the symptoms of illness in daily life. Fortunately, the current hospital technology In developed countries, hospitals have drained a lot of high-tech medical equipment, so they must be more comprehensive when treating each disease and checking their bodies.

If you feel unwell at ordinary times, you will first go to the hospital for a comprehensive examination. During the physical examination, many patients cannot escape one type of examination, that is, nuclear magnetic resonance imaging. resonance.

During the examination, doctors do not recommend MRI, and even if this examination can be avoided, It is not recommended for patients to do it. Why do doctors not recommend everyone to do an MRI? Let’s take a look.


Why is “MRI” not recommended? Doctors reveal the answer, early understanding, early benefit

First: high cost

People don’t know much about MRI, and they think that sweeping a magnetic field across the body will form a magnetic field. feedback to check the body.

NMR requires a lot of liquid nitrogen, which is relatively expensive, and everyone has to pay for nuclear magnetic resonance. Therefore, for problems that are easy and relatively easy to see, such as fever and cold, MRI is not required to avoid wasting money.

Especially if your doctor does not recommend an MRI, don’t do it alone, even if you don’t. However, the doctor’s clinical experience also judges your symptoms, so be sure to listen to your doctor’s advice.

Second: Some parts of the examination are not suitable for MRI

As we all know, the working principle of nuclear magnetic resonance has a very strong magnetic field, which can excite the hydrogen atoms in the patient’s body, and then resonate, and collect again Its signal, which translates into an image, means that there needs to be enough hydrogen atoms to examine the site.

For example, many parts have little water content, or keep beating, such as the heart and stomach, because they cannot Clear imaging, so not suitable for MRI.

Third: Claustrophobia

Many people in life will experience claustrophobia, and MRI is not recommended for such people, because claustrophobia enters a closed state and is prone to anxiety. Fear, tension, and even a sense of drowning, everyone will enter a closed state when entering the MRI, which is prone to physical discomfort, which not only brings fear to the patient’s body and mind, but also affects the test results.


In what situations would a doctor recommend an MRI?

1: Unexplained dizziness, headache, nausea and vomiting, suspected head lesions and swellTumors can be checked by MRI, which is a good means for diseases such as craniocerebral and spinal cord.

2: There are symptoms of tumor on the face, or there is a lump in the neck. After regular treatment, there is no improvement, and the doctor does not I would recommend an MRI scan.

3. Pain in the pelvic cavity and abdominal cavity, which cannot be cured for a long time, or even worsens, and there is a tumor phenomenon, do MRI The examination can detect whether there are substantial organ lesions, and has a good reference result for the early stage of uterine fibroids.

4: Persistent pain in the bones in each part of the body, or pain in the limbs, after treatment If there is no improvement, MRI should be done for examination, and MRI should be done for soft tissue damage and bone marrow lesions, as well as musculoskeletal diseases such as bone tumors or ligament strains.


Before doing an MRI, we need to pay attention to these issues

< span>1. First of all, everyone needs to understand that even if the NMR is not working, it has a very strong magnetic field. For those who are being examined, everyone must be careful about the magnetic field changes of the NMR.

2. For pregnant women, it is necessary to do less MRI, because children and pregnant women will have many uncertainties Because of the factors, doing MRI will damage the body, so it is not recommended for everyone to do it.

3. If you have metal jewelry on your hand, you need to take it down and perform it again. The magnetic fields possessed to attract each other will not only affect the normal operation of the instrument, but may also cause harm to the body.
