MRI T2 Relaxation Time of the Intervertebral Disc: Repeatability, the Effect of Time of Day, and Unloaded Rest

JOR SPINE, Volume 9, Issue 2, June 2026.
T2 relaxation time is a commonly used MRI measure of intervertebral disc degeneration. This study investigated the repeatability, as well as the effects of time of day and rest on T2 relaxation time. T2 time repeatability was primarily driven by acquisition factors while time of day and rest changes did not exceed within subject variability. Thus, this
