MRI scanners utilize strong magnets that elicit changes in the body’s hydrogen atoms. The radiation emitted by these atoms is picked up, and the innate differences in the composition of body tissues are revealed in the resulting images.
The availability of magnetic resonance imaging in International Falls from institutions such as Rainy Lake Medical Center allows modern medicine to diagnose and treat some disorders.
Modern imaging for low back pain
Since its development in the 1980s, MRI scanning has helped many persons with low back pain (LBP). While its use as a diagnostic tool for LBP remains controversial, MRI results can rule out specific conditions assisting doctors in differential diagnosis.
MRI scans rule out tumors, bone infection, and fractures. The imaging technique reveals damage to the vertebral bones and joints, spinal cartilage and ligaments, and confirm the presence of compression of the spinal cord as well as disc herniation.
In low back pain management, magnetic resonance imaging is also an essential component of pre-surgical planning, if surgery is a critical component of the patient’s management.
Do not be surprised if your doctor recommends an MRI when you consult him and her for severe acute pain on the back, and even for chronic pain, that limits movement and participation in daily life.
MRI to ascertain the cause of a headache
MRI is a non-invasive test that sees through bone tissue. As such, it can reveal the state of protected and inaccessible organs such as the brain. A cranial or brain MRI may be recommended if you are experiencing headache without a clear origin or cause.
The resulting images may reveal the presence of tumors in the central nervous system, aneurysms, and brain tissue inflammation. If there is bleeding in the brain, the MRI will show it. The same is true for swelling and abnormalities with the ventricles, or spaces within the brain that contain fluid.
MRI scanners play an important role in diagnosing complex or rare diseases and disorders. Doctors can also prescribe the procedure for certain common symptoms such as back pain and headache.
