Why do many doctors do not recommend patients to undergo MRI examinations? Three reasons, might as well understand

“Doctor, is the MRI result more accurate?”

“To a certain extent, it is.”

“Does nuclear magnetism have radiation?”

“No.”

“Then am I good at NMR? After all, CT has radiation.”

“For your situation, I suggest you check the CT first.”

Since the MRI results are more accurate and there is no radiation, why does the doctor not recommend this patient to do it? Do you know the reason? In today’s article, I’m going to talk to you about this examination. How much do you know about nuclear magnetic resonance?

First of all, what can be detected by MRI?

This test is a powerful tool for early tumor screening! It has more imaging parameters and high resolution, which can detect early tumors.

For people with three highs, the examination of the heart and other parts is beneficial to reduce the risk of cardiovascular and cerebrovascular diseases, and it can also detect hidden dangers early.

Moreover, it can also check the liver, gallbladder, uterus, and other physical organs in the human body, and has a better diagnostic function.

Although the name of this inspection gives people a very serious feeling, it actually uses a new type of imaging inspection technology. There is no radioactivity, so it is harmless to the human body.

Secondly, why some doctors do not recommend this check to patients?

Since it can detect so many problems and is safe, why do many doctors not recommend that patients check it? Have you thought of the following reasons?

Reason 1: You are not suitable for this inspection

Do you have one of these 3 situations?

  1. Have claustrophobia
  2. Taking drugs containing metal ions
  3. There are metal materials in the body, such as steel plate

If there are these conditions, it is actually not suitable for NMR, because it has a relatively small space and has a certain amount of noise. If you have claustrophobia, you may be more anxious and nervous in such an environment, which is not conducive to inspection. In addition, during the examination, if the patient has metal inside or on his body, it may affect the examination and cause unnecessary injury.

However, for the third point, it depends on the situation. For example, if a stent is placed in the patient’s body, it may not be impossible for everyone to check the MRI. Most of the stents used in clinical practice are made of stainless steel and titanium alloy, which are non-ferromagnetic or weakly magnetic. Most patients can perform this examination after a period of installation. Of course, the patient should take the initiative to inform the doctor of his condition before the examination.

Reason two: inspection time is too long

Generally speaking, the inspection takes about 30 minutes, and there is still a sound during the inspection. For some people, it may be difficult to persist. The time is long and you may need to line up. If it is an emergency, it is easy to delay time, but other tests can also be performed. At this time, the doctor may not recommend you to check the MRI, but to check the CT.

Reason three: inspection costs are high

The cost of an NMR examination is usually several hundred to thousands. If it is not necessary, it is not necessary for many ordinary families. Some doctors may not recommend you to check it. It’s not that the result of this inspection is better, and you don’t need to look at other inspections. Wouldn’t it be better to spend the least amount of money to achieve the purpose of the inspection? You can check other items first to rule out certain diseases, and you don’t need to spend any money. It is also beneficial to those who need to do this check. You may not need to queue for a long time.

Which one is better, MRI or CT?

It depends on the advantages and disadvantages of the two inspection methods. Here is a comparison:

First of all, what we can know is that NMR has no radiation, and CT has a certain amount of radiation. In the first field, NMR won.

However, you don’t need to talk about radiation discoloration. Under normal circumstances, if you do CT several times a year, the dose received by the human body is not enough to cause too much harm. It is safe. Regarding the saying that “frequent CT is likely to cause cancer”, Don’t believe it blindly. Moreover, this is not something you can do if you want, and the doctor will check it out for you.

In terms of the length of the inspection, CT was finished in a few minutes, but the time of NMR was relatively long. In this case, CT won.

In terms of inspection costs, CT is actually not very cheap. It depends on which type of inspection you are inspecting. This is considered a tie.

In addition, in terms of the scope of the inspection, the two inspection methods have their own advantages. There are also points to pay attention to before the inspection, and it is not easy to say which one is better.

Therefore, in general, NMR and CT have their own advantages and disadvantages. They are not a relationship that cannot tolerate two tigers. They complement each other. For different parts and different diseases, which one is better, it is necessary to make specific judgments. It varies from person to person.

To sum up, although the results of the MRI examination are more accurate, the scope of the examination is not completely limited. The suitability of the examination depends on your actual situation. Some doctors do not recommend the patient’s examination. This may be due to the above reasons. related. As for whether CT or MRI is better, it depends on the disease and the individual. It is not good to generalize.
