Study: Some MRI can do more harm than good for lower back pain

Jun 14, 2018 | Diagnostic Imaging

“There is a very poor relationship between changes on MRI scans and the presence or absence of low back pain," Martin Underwood, MD, a general practitioner and a professor at Warwick Medical School, told The Guardian. “If you get into the business of treating disc degeneration because it has shown up on an MRI, the likelihood is that, in most of those people, it is not contributing to their back pain.”
