Magnetic Resonance Imaging, or MRI, scans can show nerve damage, according to WebMD. An MRI of the spine can show damage to the spinal cord and associated nerves caused by both injury and disease. An MRI provides detailed images of soft tissues in the body, including the nervous system.Know More
Because an MRI works by imaging successive small slivers of the area of the body being studied, the images produced provide extreme detail that allows small anomalies on soft tissues, such as lesions on nerves, to be discovered, explains Mayfield Clinic. The soft tissues show up in different levels of brightness in the black-and-white image depending upon the amount of fluid in the tissues. This amount of detail allows doctors to diagnose soft tissue problems from tumors and pinched nerves to traumatic brain injuries and strokes. To enhance the images, sometimes the patient receives an injection of a contrast dye to highlight certain tissues.
When a doctor suspects nerve damage, an MRI is just one of several tests typically performed on a patient, says Mayo Clinic. Depending upon the symptoms a patient reports, other tests to find nerve damage include neurological examination; nerve conduction tests, or electromyography, which examine and record electrical impulses in nerves; and nerve and skin biopsies that look for abnormalities in nerves and nerve endings.Learn more about Diagnostics & Imaging
MRI scans can be useful for tracking recovery or assessing a patient's susceptibility to further injury, even after he has healed. In cases of brain damage from a stroke, MRI scans can help predict the chances of further recovery, according to NeuroImage:Clinical and posted by the National Institutes of Health.Full Answer >
According to Mayfield Clinic, a magnetic resonance imaging, or MRI, scan can reveal the presence of a pinched nerve. An MRI uses magnetic imaging to show the body's soft tissues, including nerve and brain tissue.Full Answer >
A head magnetic resonance imaging scan, or MRI, is a test that produces images of the brain using a strong magnetic field and radio-wave energy, according to WebMD. It typically offers useful information that X-ray, ultrasound and computer tomography scans cannot provide.Full Answer >
According to WebMD, an open MRI is a magnetic resonance imaging machine that has a larger opening than a standard MRI machine. Some open MRI machines do not completely surround the body, but such machines cannot perform certain MRI scans.Full Answer >
