From: T1ρ, T2 and T2* mapping of lumbar intervertebral disc degeneration: a comparison study
Representative images of sagittal T2-weighted images, T1ρ map, T2 map and T2* map. Five oval regions-of-interest (ROIs) were firstly placed on the T2-weighted images (A), then the ROIs were transferred to the T1ρ map (B), T2 map (C), and T2* map (D). The central three ovals (included in one red oval) represent nucleus pulposus, and the ventral and dorsal one represents anterior annulus fibrosus and posterior annulus fibrosus, respectively
