With several kinds of nerve diseases and damages appearing in day to day medical case studies, the physicians are finding the advanced technology of Neuroimaging exactly suited for diagnosing for such brain related problems. Brain X-Ray is the most important method applied nowadays for the detection of Nerve diseases and their diagnosis leading to a proper medical attention before hand.

Brain imaging techniques are only applicable for those diseases that involve damage and lesions in the brain. These diseases often associated with dementia come under biological psychiatry. Several neural disorders are also under clinical psychiatry and they, including depression, anxiety, phobia and mania often cannot be identified by Neuroimaging.
Brain mapping is the other name for the technology of Neuroimaging dealing with taking pictures of brain. The fascinating process can be broadly classified into two categories. They are: 1) Structural Imaging and 2) Functional Imaging. The former is the basic structural analysis of the brain often detecting tumor and injury, while the latter involves an analysis in a finer tune to detect the effects of minute lesions and damages in the malfunctioning brain from nerve diseases. The diagnosis of certain nerve damaging maladies like Alzheimer's disease involves such Functional Brain Mapping techniques.
Depending on the diseases and their complications there are several forms of Neuroimaging used. The most widely used is the CAT, commonly called CT Scan. The CAT is an abbreviated form of the term Computed Axial Tomography. This kind of CT Scan involves a computer aided program that goes through a series of mathematical calculations at a fairly rapid pace to tag the brain dysfunctions caused by lesions, injuries and damages involved in the superficial area of the brain.
Another kind of Medical Imaging proved to be effective for identifying the damaged parts of the brain with a higher degree of anatomical details is the MRI, or, Magnetic Resonance Imaging Technology. MRI is a type of Brain Neuroimaging that animates the three dimensional structure of the brain along with the damages and dysfunctions using magnetic fields and radio waves. The other form of MRI is fMRI, or, functional form of the Neuroimaging technology where finer resolutions are possible in studying the damaged areas of the affected brain.
PET is a very advanced form of the Neuroimaging technology actually known to be Positron Emission Tomography, detecting the radiations from radio labeled metabolically active chemicals that have been injected into the affected cells of the brain. This tracing technology can be tuned to even finer levels two and three dimensional detections of the damaged brain. Other effective forms of Neuroimaging following the lines of PET are SPECT, or, Single Photon Emission Computed Tomography and DOT, or, Diffused Optical Tomography.
