Clinical Importance of Neuroimaging Techniques_1

CLINICAL IMPORTANCE OF NEUROIMAGING TECHNIQUES Neurological deaths have become an issue globally; this is due to the increase in the number of neurological disorders. Researchers have developed neuroimaging techniques to curb or reduce the number of deaths. Neuroimaging also called brain imaging techniques include the following magnetic resonance imaging, electroencephalography, magnetoencephalography, near-infrared spectroscopy and chromatography scan.MAGNETIC RESONANCE IMAGING Magnetic resonance imaging (MRI) has been used by clinicians to check for the extent of brain damage caused by trauma. The abrupt increase in brain injuries caused by trauma has been approved to have affected most people globally with about 100 to 550 per 100,000 people annually (Vos et al., 2012, p.207-219). In MRI scan the patient head is laid on a machine which uses strong magnets and radio frequency which is later sent to the computer. It shows if the braintissue is damaged or if there is bleeding in the brain or a nerve injury. Sometimes a dye is given through a vein before the scan is performed to show pictures of the brain more clearly.MRI has also been used by clinicians to check for brain tumors in the brain. Cancer has become a major problem affecting individuals globally. The major common signs and symptoms of a tumor include disorder in the movement of the limb, lack of sensation in some parts of the body, vision and speech disturbance (Kimura et al., 2013, p.233-238). Contrast agents have been used to visualize clearly the size, vasculature, and hemorrhage within the tumors since this features cannot be seen with formal imaging. MRI has also been used to check for cancer in its early stages, it has been used to check for a mass if the client has been showing signs that my call for a

tumor and the stage of the client's cancer and lastly plan for treatment of the client (Gilles et al., 2012, p.633-638). MRI has been used to check for lesions in the brain and spinal cord caused by multiple sclerosis, which is known to have been caused by demyelination of the nerves of the central nervous system which is considered to be an autoimmune disorder. White matter in the brain andspinal cord is known to be affected most. The symptoms of multiple sclerosis include fatigue which gets worse after exercising; vision problems or sometimes a temporary loss of vision, partial or total lack of sensation, problems with movements and neuropathic pain.MRI has been used for examination, identifying the nature or cause of the disease and treatment of multiple sclerosis (Gallagher et al., 2013, p.439-441). It’s the most used imaging technique for a patient with multiple sclerosis.MRI has been used to show lesions in the corpus callosum. Clients with multiple sclerosis manifest with a large number white matter plaques. MRI has been used in the diagnosis of dementia; this scan is usually done to rule out other diseases that may have the same signs and symptoms. Dementia is a gradual decrease in mental ability which affects the intellectual process. The signs and symptoms include memory loss, difficulty in communication, a decrease in the reasoning and judgment (Breteler et al., 2014, p.1246-1252). Dementia is due to damage to the brain cells which affects the ability of other brain cells to transmit information to each other. FUNCTIONAL MAGNETIC RESONANCE IMAGING Functional magnetic resonance (fMRI) is a method used in evaluating the brains behavior. It functions by observing the blood flow in the brain that occurs after a neuronal activity. The brain
