What Student Need to Know about Principles of Neuroimaging ( Brain Imaging) In Radio Diagnosis

Neuroimaging, or brain scanning, includes the use of various techniques to directly or indirectly image the structure, function, or pharmacology of the brain. It is a relatively new discipline within medicine, neuroscience, and psychology. Physicians who specialize in the performance and interpretation of neuroimaging in the clinical setting are known as neuroradiologists. Neuroimaging falls into two broad categories: Structural imaging, which deals with the structure of the brain and the diagnosis of largescale intracranial disease (such as a tumor), as well as injury. Functional imaging, which is used to diagnose metabolic diseases and lesions on a finer scale (such as Alzheimers disease), and also for neurological and cognitivepsychology research. Functional imaging allows the brains information processing to be visualized directly, because activity in the involved area of the brain increases metabolism and lights up on the scan. Four of the most common types of brain scans are EE
