Routine spine imaging not needed for most back pain cases

Most cases of acute low back pain resolve without an MRI, CT scan or X-ray, and international guidelines do not recommend routine imaging for uncomplicated back pain unless warning signs are present. Spine scans often reveal age-related changes such as disc bulges or degeneration that may be unrelated to the pain, leading to unnecessary anxiety and interventions.

Imaging is indicated when there is significant trauma, a history of cancer, unexplained weight loss, fever, or progressive neurological weakness such as numbness, difficulty walking, or bladder and bowel control problems. These could signal a serious condition like cauda equina syndrome requiring urgent MRI.

For simple back pain, the first step is clinical evaluation, pain management, staying active, and physiotherapy if needed. The goal is to order the right scan for the right patient at the right time, not more scans.
