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.Continue Reading
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
Some patients need to visit MRI centers to undergo scans, which create images with more detail than X-rays, ultrasounds and CAT scans, according to Mayo Clinic. An MRI takes detailed images of the brain, spinal cord, skeleton, chest and lungs, and abdomen, as well as other body areas, explains KidsHealth.Full Answer >
Reliable information concerning the risks of MRI scans may be found online at the Mayo Clinic or the FDA. Risks for patients undergoing an MRI generally include any metal in the body or pregnancy, notes Mayo Clinic. Artificial limbs, pacemakers or medical implants are important to mention before MRI testing.Full Answer >
According to WebMD, doctors use MRI scans to obtain information about the organs and internal structures that X-rays, ultrasounds and CT scans do not provide. MRI scans are pictures of the head, chest, bones, blood vessels, abdomen, pelvis and spine. They are used to look for tumors, bleeding, injury, infection and various blood vessel diseases.Full Answer >
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 >
