Most people will experience a Magnetic Resonance Imaging MRI at some point in their lives. Whether it’s to assess a broken bone or get a closer look at soft tissue, this imaging technology is one of the best tools health practitioners have to determine the damage done inside the body. This simple test is very non-invasive and can be done in as little as 30 minutes (or 2 hours at most). Many patients lie inside the machine, wearing headphones, with their eyes closed as though they are resting. Meanwhile, the magnets whir around them, producing images that can help doctors in their diagnosis and treatment.
Before the Magnetic Resonance Imaging MRI came along, cutting a person open was the best way to assess damage. Now, diagnostic imaging can be used to let patients know if they have multiple sclerosis, brain tumors, pituitary gland tumors, brain infections, spinal cord infections, joint deformities, tendonitis or stroke. An MRI scan can also reveal torn ligaments in knees, wrists and ankles, as well as the progression of a shoulder injury. The MRI is, in fact, very similar to an x-ray, although an x-ray cannot examine soft tissues, tumors, cysts and herniated discs as the MRI can.
To prepare themselves for the MRI scan, patients will let their medical practitioner know if they are allergic to any medications, are pregnant, have a pacemaker or metal implants, have had an accident that may have left metal shards in their bodies, have had recent blood vessel surgery, have an intrauterine device, suffer from claustrophobia, wear medication patches or suffer from conditions like sickle cell anemia that may react poorly to the contrast material. Often patients will bring someone to drive them home after the test because sedatives are sometimes administered.
Magnetic Resonance Imaging MRI technology has given physicians unprecedented glimpses into the human body, without needing to cut the patient open. While x-rays are good at revealing broken bones, fractures and slipped discs, the MRI technology is better at ascertaining the condition of surrounding soft tissue, which can be very helpful in assessing more than one medical problem. In the future, we will likely see many advances to this amazing technology. Researchers are looking at how to make the machine quieter, less confining and more efficient at producing images, whether a person is moving or not.
