Fig. 1From: Safety and tolerability of intradiscal implantation of combined autologous adipose-derived mesenchymal stem cells and hyaluronic acid in patients with chronic discogenic low back pain: 1-year follow-up of a phase I studyMeasurement of the apparent diffusion coefficient (ADC) in lumbar degenerated discs. Mid-sagittal T2-weighted images were chosen and a region of interest (ROI, 50Â mm2) placed in the central half of each disc. Sagittal fast spin echo (FSE) T2-weighted images (a) and diffusion-weighted images (DWI) with b factors of 0 (b) and 500Â s/mm2 (c). ROI in the T2-weighted image copied to the ADC map from the DWI at the same level (d)Back to article page
