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
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 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 >
Magnetic resonance imaging, or MRI, is a test that can detect disease or tissue damage such as inflammation, infection, stroke, tumors and seizures, according to WebMD. An MRI can see information about the body that is not visible through other means such as an X-ray, CT scan or ultrasound.Full Answer >
The use of a magnetic resonance angiogram is often more accurate than a CT scan or an ultrasound in certain diagnostic tests, according to WebMD. MRA testing is done to detect problems in the blood vessels that lead to the brain, issues with the aorta and narrowing of other blood vessels.Full Answer >
