Chapter 3238 【3238】Disputed Area

The principle is very simple. If any area of ​​the brain is active, its brain oxygen consumption will increase.

The reason why fMRI is rarely heard clinically is that it is mainly used in psychological research.

We have said that in the study of psychology, if it is a materialist theory, it must be based on anatomy. Psychologists therefore use this test as an anatomical basis for observing human brain activity.

is that useful?

fMRI has flaws. The flaw lies in its low spatial resolution. In order to improve its resolution, it is nothing more than using noise reduction algorithms and other means. You can compare these processing methods to post-editing of audio and video. The post-modification is naturally too much affected by the operator's human factors, which may distort the original data and cause deviations in the results.

The experimental data was distorted, and medical ethics issues emerged.

Because some psychological research results will be applied to difficult social problems, such as the polygraph that has been popular for a while, in fact, some experiments use this fMRI. If such a polygraph is used in court to judge whether a person is guilty or not of murder, you say that this problem is not terrible or terrible.

Moreover, some lawyers will use fMRI to exonerate the murderer, saying that the abnormal EEG of the criminal has a mental illness, which can help the criminal escape the death penalty.

Now we are talking about a vegetative person, who has abnormal brain activity and sleep. According to the principle of fMRI, it can help doctors observe the brain activity of patients, and help doctors judge the prognosis of this patient and whether more radical treatment methods can be adopted.

It just so happens that for a vegetative person, the most effective thing is not to look at the treatment, but to judge whether the patient has a chance to wake up after being stimulated.

Here I want to talk about the new classification of vegetative people that has been heatedly discussed in the medical circle in this era and is about to be released.

In the past, what is a vegetative person, the doctor only needs to make an order, and the patient can be called a vegetative person if he cannot follow the doctor's order. It was later discovered that one of these patients could open their eyes, and the eyeballs could respond to the doctor's instructions. Such patients were then assessed by fMRI to determine residual conscious activity. Doctors will give them a more accurate definition of such patients as patients in a minimally conscious state, which is different from a vegetative state.

After the new classification, it will be found that nearly half of the former vegetative people are not vegetative, but patients in a state of minimal consciousness. It shows that this new classification greatly affects clinical judgment.

When discussing these newest academic topics, the bosses are inevitably full of enthusiasm. Dr. Charlie was in high spirits and said, "Well, well, you, a medical student, actually understand this world's cutting-edge neurosurgery topic, which shows that you are very interested in neurosurgery. learn.

Xie Wanying could feel her back being patted by Brother Cao's gentle hand. It can be seen that Brother Cao is also very satisfied with her performance.

Dr. Charlie said that when he talked about the First Affiliated Hospital of Zhongshan Medical College, he participated in the bedside consultation of this patient, and the suggestion she gave was fMRI.

As expected of the world's top neurosurgery boss, he has a clear grasp of the cutting-edge medical methods.

There was no conclusion on the spot whether the other hospital adopted his academic point of view. Everyone is very controversial. Who made the new classification of vegetative people all over the world unreleased.

From here, we will find that the standard setting of an industry can directly affect clinical work and patients.
