The objective of our study was to assess the relationship of morphologically defined lumbar disc pathology with quantitative T2 mapping. Segmental evaluation of 265 discs of 53 patients with low back pain was performed and T2 values in different disc compartments were compared to different kinds of disc pathology. T2 mapping in the lumbar spine at 3 Tesla yields additional information about the disc matrix and is a promising noninvasive tool to assess water content and collagen fiber integrity in different disc pathologies.
