T2- and diffusion-maps reveal diurnal changes of intervertebral disc composition: an in vivo MRI study at 1.5 Tesla.

PURPOSE To investigate the lumbar intervertebral discs (IVDs) by MRI in the morning and evening after a diurnal load cycle. Changes in MR characteristics (T2-weighted imaging, T2- and apparent diffusion coefficient [ADC] -mapping) during the course of the day were visualized and analyzed visually and quantitatively. The length of the lumbar spine was… CONTINUE READING
