Chapter 108: Brain Magnetic Field Response?

"Doctor Zhao, that girl just now can't really be a brain tumor, right?"

After the old couple took the girl to do an MRI, Song Wei suddenly said to Zhao Sheng with some regret.

"It's normal to have headaches, and many times it will occur due to poor rest or other reasons, but if you have aphasia, the specificity is very high."

Zhao Sheng thought for a while and said.

Illness is fair, and it will not be treated differently because of good and evil, beauty and ugliness, young and old.

As a clinician, if you have the stereotype that you don't get a certain disease at any age, sometimes you will suffer a lot because of it.

In other words, this is a kind of thinking inertia, when everyone encounters a new thing, they will first find a reference object to understand from the field they are familiar with, which is a kind of "anchoring" psychology, or mindset.

In the process of diagnosis or treatment, clinicians gradually form certain fixed concepts or tendencies based on their own experience or experience in the understanding and treatment of certain diseases or clinical situations, as well as some individual experiences of reading, and fail to objectively adopt or study all kinds of information given in clinical practice.

For example, when facing a patient with a suspected tumor, it is stereotyped that the patient is unlikely to have a tumor because of his age.

There is also a kind of problem, that is, thinking willfulness, which is to look at objective things one-sidedly and superficially only based on subjective impressions and without looking at reality.

The characteristics of the disease are often atypical in clinical manifestations, and the same disease can have multiple manifestations, and different diseases can have the same manifestations.

To put it simply, it is necessary to reduce subjective judgments, judge the disease more from objective "evidence", respect the results of logical inference based on facts, and maintain objective rationality.

"It's a shame if it's really a brain tumor."

Song Wei said with some sighs.

The kindergarten girl just now, she is so beautiful, her temperament is also very good, and her work is good, how many girls dream of what they want to grow up.

"Don't presuppose this diagnosis, everything is based on the results of the test."

Hearing Song Wei's words, Zhao Sheng shook his head slightly and said.

If the students under his command say so, then he must educate them well.

Without a full understanding, presetting a diagnosis for a patient in the clinic and presetting a position in the world can be fatal at a critical moment.

"I'm just talking, I'm not a doctor."

Song Wei said.

At this time, the little nurse Yu Ning hurriedly rushed into the consultation room, and as soon as she saw Zhao Sheng, Yu Ning said very anxiously: "Teacher Zhao, the patient fainted during the examination in the MRI room!" ”

"What?!"

Hearing this, Zhao Sheng stood up suddenly, and Song Wei was also nervous.

"Let's go!"

Zhao Sheng didn't care about saying anything, and Song Wei hurriedly left the consultation room and ran towards the MRI room.

Soon, in less than five minutes, Zhao Sheng and Song Wei arrived at the MRI room.

However, at this moment, the girl has been helped by Guo Yan, the doctor of MRI, to sit on the bench outside the examination room, looking at her face, she has just woken up, and she looks like she has not fully woken up.

"Doctor Zhao, you're here."

Seeing Zhao Sheng coming, Guo Yan breathed a sigh of relief, this good person was already lying in the inspection cabin, he had just started the machine, but the girl who was lying down suddenly tilted her head and fainted, which scared him.

Because before the girl had been examined, he had also asked about the relevant contraindications and medical history in detail, and judging from her appearance, she did not look like a person who would suddenly faint.

The most important thing is that there are very few contraindications for MRI, the most important is that there are metal implants in the body, and people with claustrophobia and ear diseases may not be able to tolerate the relatively confined and confined space when the MRI is examined.

"Well, I'll leave it to me."

Zhao Sheng nodded at Guo Yan.

"Doctor, what's wrong with Shanshan? Why did you suddenly pass out? ”

The old lady stood next to her and asked Zhao Sheng very anxiously.

Before, I just had a headache and couldn't speak, but now it's good, I just fainted, how can this not make the old lady anxious.

Zhao Sheng first checked the girl's nervous system-related signs, and found that there was no major problem, and when the girl's demeanor looked sober, Zhao Sheng asked the girl: "How did you feel before you passed out just now?" ”

When the girl heard this, she took out her mobile phone and typed two big characters with some difficulty

【Headache】

Seeing that the girl was typing with her mobile phone, it was no longer as clear as when she first came, and she could only type two words or two words, Zhao Sheng knew that this was a problem with her cognitive function.

"Doctor Guo, when you passed out, did the machine turn on?"

Zhao Sheng thought for a moment and asked Guo Yan, the examining doctor.

In the current situation, the possibility of claustrophobia is not great, and Zhao Sheng has asked about this medical history before.

"It's already opened, but it doesn't have much to do with whether it can be opened or not. In the case of nuclear magnetism, from the beginning of installation, the magnetic force of this machine has always been in the state of being turned on, and this magnetic field has always been there. ”

Guo Yan thought that Zhao Sheng was guessing that the strong magnetic field of the MRI had affected the girl and made her faint suddenly, so he explained.

"Dr. Guo, I remember that this MRI is 5.0T, right?"

Zhao Sheng nodded and asked Guo Yan again.

The principle of nuclear magnetic resonance is based on the biomagnetic spin imaging technology combined with resonance and radio frequency pulse technology, and the generated pulse signal is generated by frequency conversion to form an image generation through the principle of rotation of the atomic nucleus by pulsed radiation.

Domestic NMR is generally 1.5T to 3.0T, and this 5.0T NMR is the result of the latest research.

How strong is a 5.0T magnetic field?

There was a news before, a patient in a hospital, because of an MRI, accidentally pushed the wheelchair in, but the wheelchair was sucked by a strong magnetic field, and six or seven big men worked together, but they couldn't pull it down.

The human body naturally has a magnetic field, and although the magnetic field is very weak and difficult to detect, there is no doubt that there will be a reaction between the human magnetic field and a strong magnetic field such as 5.0T.

It's just that this reaction is extremely weak, and under normal circumstances, the changes in the human body caused by this reaction cannot be actively detected by human beings at all.

"Even if this MRI has 5.0T, it can't trigger a response from the magnetic field of the human brain, or even a coma, right?"

Zhao Sheng just asked, Guo Yan knew what he wanted to express, and said very suspiciously.

He had also encountered cases of fainting after MRI, but it was because of a sudden onset of some kind of disease, such as transient cerebral ischemia and so on.

If you really want to say that because of the strong magnetic field reaction of the patient's brain and MRI, the patient fell into a coma, this is pure nonsense, or even science fiction.
