Objective To correlate magnetic resonance (MR) image findings with pain response by provocation discography in patients with discogenic low back pain, with an emphasis on the combination analysis of a high intensity zone (HIZ) and disc contour abnormalities. Materials and methods Sixty-two patients (aged 17–68 years) with axial low back pain that was likely to be disc related underwent lumbar discography...

Comparison of pain responses from suspected symptomatic discs with pain responses from asymptomatic negative discs is routine.
