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.
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
An MRI, or magnetic resonance imaging, is used to scan the body to identify problems in soft tissues, such as nerves, ligaments, tendons and muscles, according to Alliance Medical. An MRI highlights contrasts in soft tissues to identify infections or inflammatory conditions, too, according to the Nemours Foundation.Full Answer >
There is no definite estimate of ultrasound scan accuracy, especially when detecting disabilities of a fetus, according to British College of Obstetricians and Gynaecologists member Dr. Joseph S.K. Woo. However, NHS Choices states that internal and endoscopic procedures are more reliable than external ultrasounds.Full Answer >
Magnetic resonance imaging (MRI) is a noninvasive computerized diagnostic technique that uses strong magnetic fields and radio waves to develop an image of the inside of the body, according to Johns Hopkins Medicine. The process does not use potentially dangerous radiation the way that X-rays and CT scans do.Full Answer >
The Encyclopedia of Children’s Health states that the purpose of an MRI, which stands for magnetic resonance imaging, is to generate images of the body to assist doctors in diagnosing diseases or conditions and evaluating injuries. Additionally, the National Health Service explains that the results of an MRI scan are useful in planning treatments and assessing the effectiveness of a previous treatment.Full Answer >
