Answer:
encephalectomy (EPA)
Explanation:
There is no such imaging technique available for brain scan.
Magnetoencephalography (MEG) is a method used to calculate brain's magnetic field shifts due to external sensations, such as bodily touches or meal photos. The electric activity (current) in the brain induced such a shift in the environment.
Positron-emission tomography is a practical technique in nuclear medicine that is used to monitor body metabolism to help diagnose disease. A brain positron emission tomography (PET) scan is an imaging procedure that helps doctors in seeing how the brain works. The mri shows photos of brain function after nuclear tracers were ingested into the bloodstream. Such tracers are "linked" to the glucose compounds.
Blood-related changes are observed by functional MRI to test brain activity. The assumption that blood flows and neuronal activity are intertwined is the basis of this technique. Blood flow towards this area also tends to increase whenever a region of the brain is used.
