An MRI is a very powerful diagnostic tool that can show problems with muscles, ligaments, tendons, discs and soft tissue that x-rays cannot show. Unfortunately this strength can become a problem if not properly used. A new study showed that when low-back MRIs were performed early in treatment, future medical costs greatly increased, as did the risk of unnecessary testing or treatments such as electromyography, nerve conduction testing, advanced imaging, injections, and surgery. Some patients will certainly need these tests or treatments, but for many they are unnecessary.

One potential explanation is that MRIs can often show degenerative or age-related changes unrelated to the workplace injury or symptoms. This is costly to the employer and insurer and potentially harmful to the patient, who may undergo needless testing or surgery as a result. Previous studies have shown a very high rate of “abnormal” MRIs among people who are not suffering from any pain. Therefore, it is not unreasonable that an MRI of an individual who reports back pain would show abnormalities that are unrelated to the workplace accident. While Georgia law allows the authorized treating physician to prescribe MRI scans, it is appropriate to confirm the necessity of specific testing before approval in cases that do not involve recent severe trauma or infection.
