The Association Between Magnetic Resonance Imaging Disc Pathology and Provocative Discography at the Lumbar Level.

Objective: The objective of this study was to show that degenerative lumbar magnetic resonance imaging findings variably increase discography pain by level.

Methods: Lumbar discography and magnetic resonance imaging of 736 patients were retrospectively reviewed. Univariate/multivariate logistic regressions calculated the odds ratio (OR) (95% confidence interval, P < 0.

Modic changes on MR images as studied with provocative diskography: clinical relevance--a retrospective study of 2457 disks.

Purpose: To assess the value of vertebral body endplate signal intensity (Modic) changes on magnetic resonance (MR) images in predicting a painful disk, with provocative diskography as the reference standard.

Materials And Methods: Lumbar spine diskograms and prediskogram MR images of 736 patients (2457 disks) were retrospectively reviewed as part of an institutional review board-approved HIPAA-compliant protocol. Each disk was assigned a Modic subtype: type 0, normal; type 1, nonfatty high signal intensity; type 2, fatty; and type 3, sclerosis.
