Chapter 3238: ?3248?Disputed area
The principle of ?? is very simple. If any area of ??the brain is functionally active, its brain oxygen consumption will increase.
The reason why ??fMRI is less clinically heard is that it is mainly used in psychological research.
?? Psychological research We have said that if it is materialism, it is based on anatomy. Psychologists therefore use this test as the basis for anatomically observing human brain activity.
is that useful??fMRI has defects, and the defect is its low spatial resolution. In order to improve its resolution, it is nothing more than to use noise reduction algorithms and other means. You can compare these processing methods to post-editing of audio recordings. late
The modification of ?? is naturally greatly influenced by the operator's human factors, which may distort the original data and cause deviations in the results.
??The experimental data is distorted, and medical ethics problems come out.?Because some psychological research results will be applied to difficult social problems, such as the polygraph that was popular for a while, in fact, some experiments use this fMRI. If such a lie detector is used to judge people in court
??Whether he is guilty or not, whether to kill or not, you say this question is not too scary or not.
?? And some lawyers will use fMRI to exonerate the murderer, saying that the criminal's abnormal EEG has a mental illness and can help the criminal escape the death penalty.? Now we are talking about a vegetative person, and a vegetative person is sleep with abnormal brain activity. According to the principle of fMRI, it can help doctors to observe the activity of the patient's brain, and help doctors to judge the prognosis of the patient and whether
?? More aggressive treatments are available.
?? As it happens, for a vegetative person, the most effective method is not to look at the treatment method, but to determine whether the patient has a chance to wake up after being stimulated.
?? Here we are going to talk about the new classification of vegetative people that is hotly discussed in the medical circle in this era and is about to be released.?In the past, what is a vegetative state, as long as the doctor makes an order, and the patient cannot follow the doctor's order, it can be called a vegetative state. Later, it was found that some of these patients can open their eyes, and the eyeballs can
?? Respond to your doctor's instructions. This patient was then assessed by fMRI and determined to have residual conscious activity. Doctors will give them a more accurate definition of such patients called micro-conscious state patients, different from a vegetative state.
??After the new classification, it will be found that nearly half of the former vegetative people are not vegetative people, but patients with micro-consciousness. It shows that this new classification has a great influence on clinical judgment.?When discussing these newest academic topics, the big guys are just as enthusiastic. Dr. Charlie is in high spirits, saying: Okay, you, a medical student, actually understands this world-leading neurosurgery topic.
?? Interested and knowledgeable about neurosurgery.
?? Xie Wanying could feel her back being patted by Brother Cao's gentle hand. It can be seen that Senior Brother Cao is also very satisfied with her performance.
?? Dr. Charlie said, referring to the First Affiliated Hospital of Zhongshan Medical College, who participated in the bedside consultation of this patient, and gave the fMRI advice she mentioned.
?? worthy of being the world's top neurosurgery boss, he has a clear understanding of the cutting-edge medical methods and masters the universe.
?? The other hospital adopted or rejected his academic views, and there was no conclusion at the scene. Everyone is controversial. Who made the new classification of vegetative people in the world not released.?From here, we will find that the standard setting of an industry can directly affect clinical work and patients.
