The principle is very simple. If any area of the brain is active, its brain's oxygen consumption will increase.
The reason why fMRI is rarely used in clinical practice is that it is mainly used in psychological research.
As we have said in psychological research, if it is a materialistic theory, it must be based on anatomy. Psychologists therefore use this examination as a basis for anatomical observations of human brain activity.
is that useful? fMRI has flaws, and the flaw lies in its low spatial resolution. 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 recorded images. later stage
The modification is naturally greatly affected by the operator's human factors, which may distort the original data and lead to biased results.
The experimental data is distorted, and medical ethics issues arise. Because some psychological research results will be applied to difficult social issues, such as the lie detector that became popular for a period of time, some experiments actually used fMRI. If such a polygraph is used to judge people in court,
Whether he is guilty or not, whether he is guilty or not, is this a big or scary question?
Moreover, some lawyers will use fMRI to exonerate murderers, saying that the criminal's abnormal electroencephalogram indicates mental illness, which can help the criminal escape the death penalty. What we are talking about now is vegetative state, which means sleeping with abnormal brain activity. According to the principle of fMRI, it can help doctors observe the activity of the patient's brain, and help doctors determine the patient's prognosis and whether
More aggressive treatments are possible.
It just so happens that for a vegetative person, the most effective way is not to look at the treatment method first, but to determine whether the patient has a chance to be stimulated and revived.
Here I want to talk about the new classification of vegetative state that is being heatedly discussed in the medical circle in this era and is about to be released. In the past, what was a vegetative state? The doctor only had to give instructions. If the patient could not follow the doctor's instructions, he could be called a vegetative state. Later it was discovered that one type of these patients could open their eyes.
Respond to doctor's instructions. Such patients are judged to have residual conscious activity through fMRI evaluation. Doctors will give these patients a more accurate definition as patients in a minimally conscious state, which is different from a vegetative state.
After the new classification is completed, it will be found that nearly half of the previous vegetative patients are not vegetative patients, but patients in a minimally conscious state. This shows that this new classification greatly affects clinical judgment. When discussing these latest academic topics, the bosses were inevitably very excited. Dr. Charlie was in a high mood and said: Okay, okay, you, a medical student, actually understand this cutting-edge neurosurgery topic in the world. It shows.
Very interested and knowledgeable about neurosurgery.
Xie Wanying could feel her back being patted by Senior Brother Cao's gentle hand. It can be seen that Senior Brother Cao is also very satisfied with her performance.
Dr. Charlie said that she went to the First Affiliated Hospital of Zhongshan Medical College and participated in the bedside consultation of this patient. The suggestions she gave included fMRI.
He is worthy of being one of the world's top neurosurgery experts, with a thorough understanding of cutting-edge medical methods.
There is no conclusion on the spot whether the other hospital will adopt the academic opinions he said. It's quite controversial. Who made the new classification of vegetative people around the world yet to be released? From here you will find that the setting of standards for an industry can directly affect clinical work and patients.
