Neuroimaging involves the various techniques involved in imaging of the brain and thus helping us to know the structure function relationship of the brain. Functional imaging is also used for the diagnosis of the various metabolic diseases such as Alzheimer’s disease and can be used for the cognitive physiology and neurological physiology. CT(Computed tomography) scanning is a type of neuroimaging technique that use x-rays for imaging the brain from various angles. Techniques are emerging in the field of neuroimaging for getting the technique better every time.
