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.Know More
During the MRI test, the patient lies on a bed that slides into the tube-shaped MRI machine, states Mayfield Clinic. The examination generally lasts between 20 and 50 minutes.
According to Mayo Clinic, doctors suspect a pinched nerve if the patient experiences numbness, tingling, sharp pain or muscle weakness. A pinched nerve occurs when pressure from bones, tendons, cartilage or muscles places pressure on the nerve, preventing it from functioning properly.Learn more about Diagnostics & Imaging
According the U.S. Food and Drug Administration, no known side effects are associated with magnetic resonance imaging, or MRI, but some risk factors should be considered before undergoing the procedure. People who have pacemakers, artificial limbs or other implanted medical devices, face a risk of malfunction or the heating up of these devices during the procedure. Comprehensive screening is conducted before an MRI to prevent this reaction.Full Answer >
A magnetic resonance imaging, or MRI, machine surrounds the patient with a magnetic field and emits radio waves to generate cross-sectional images, according to Mayo Clinic. A positron emission tomography, or PET, scanner detects radioactivity in the body after the patient is given a special radioactive tracer chemical.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 >
When a bulging disc appears on a magnetic resonance imaging test, or MRI, the disc protrudes from its accustomed place between vertebrae, according to the Laser Spine Institute. It resembles a hamburger that sticks out beyond the edges of its bun, Mayo Clinic explains.Full Answer >
