RT Journal Article T1 Informed appropriate imaging for low back pain management: A narrative review. A1 Wáng, Yì Xiáng J A1 Wu, Ai-Min A1 Ruiz Santiago, Fernando A1 Nogueira-Barbosa, Marcello H K1 Imaging K1 Low back pain K1 Natural history K1 Radicular pain K1 Radiculopathy K1 Spine AB Most patients with acute low back pain (LBP), with or without radiculopathy, have substantial improvements in pain and function in the first 4 weeks, and they do not require routine imaging. Imaging is considered in those patients who have had up to 6 weeks of medical management and physical therapy that resulted in little or no improvement in their LBP. It is also considered for those patients presenting with suspicion for serious underlying conditions, such as cauda equina syndrome, malignancy, fracture and infection. In western country primary care settings, the prevalence has been suggested to be 0.7% for metastatic cancer, 0.01% for spinal infection and 0.04% for cauda equina syndrome. Of the small proportion of patients with any of these conditions, almost all have an identifiable risk factor.
