The principle is very simple. If any area of ​​the brain is active, its brain oxygen consumption will increase.
The reason why fMRI is less clinically listened to is because it is mainly used in psychological research.
Psychological research we have said that if it is materialistic theory, it should be based on anatomy. Psychologists therefore use this examination as a basis for anatomically observing human brain activities.
Is it useful? fMRI has defects, and the defect is that it has low spatial resolution. To improve its resolution, it is nothing more than using noise reduction algorithms. For these processing methods, you can compare it to post-production editing of recording images.
The modification is naturally too much affected by the operator's human factors, which may cause the original data to be distorted and lead to a deviation in the results.
Experimental data is distorted, and medical ethics problems have emerged. Because some psychological research results will be applied to difficult social problems, such as the lie detector that was popular for a period of time, in fact, some experiments use this fMRI. If such a lie detector is used in court to judge people
Whether you are guilty or not to kill someone, do you think this question is terrible or not?
Moreover, some lawyers will use fMRI to relieve murderers of crimes, saying that the criminal's EEG is abnormal and mentally ill, which can help the criminal get rid of the death penalty. Now we are talking about vegetatives, which are abnormal brain activity. According to the principle of fMRI, it can help doctors observe the patient's brain activity, help doctors judge the prognosis of the patient and whether or not
More radical treatments can be taken.
Just so, for vegetatives, the most effective way is not to look at the treatment method, but to determine whether the patient has the chance to wake up after being stimulated.
Here we will talk about the new classification of vegetative people that was discussed fiercely in the medical circle in this era and is about to be released. In the past, what was vegetative? Doctors only had to give instructions, and patients could be called vegetative people if they could not follow the doctor's instructions. Later, it was found that one of these patients could open their eyes and the eyeballs could
Respond to the doctor's instructions. This type of patient is then evaluated by fMRI and determined that he has residual consciousness activity. This type of patient doctor will give them a more accurate definition called a microconscious patient, which is different from a vegetative person.
After the new classification, you will find that nearly half of the previous vegetatives were not vegetatives, but patients with micro-consciousness. This shows that this new classification has a lot to do with clinical judgment. When discussing these new academic topics, the boss is still very excited. Dr. Charlie was in high spirits and said: OK, okay, you, a medical student, actually understand this world's cutting-edge neurosurgery topic, which shows that
I am very interested in neurosurgery and know very well.
Xie Wanying could feel that her back was patted by Senior Brother Cao's gentle hand. It can be seen that Senior Brother Cao was also very satisfied with her performance.
Dr. Charlie said that when she was at the First Affiliated Hospital of Zhongshan Medical College, she participated in the bedside consultation of the patient, and the suggestions she gave were fMRI.
He is worthy of being the top international neurosurgery master, and he is well aware of cutting-edge medical methods.
