Understanding Imaging Tests
MRI (Magnetic Resonance Imaging) provides detailed images of the spine and is more sensitive than X-rays. However, it's not always the best first step for diagnosing back pain. Over 85% of back pain cases resolve without any imaging.
When is Imaging Necessary?
Imaging is often reserved for cases with severe symptoms or risk factors for serious conditions like cancer or infection. If you have neurological deficits or symptoms persist beyond six weeks, your doctor may recommend an MRI.
The Downsides of Unnecessary Imaging
Getting an MRI too soon can lead to unnecessary treatments and increased healthcare costs. Many findings, like disc herniations, are common in people without pain and may not be the cause of your symptoms.
