Flow-driven perfusion studies of cryogels with different CMC% composition using MRI. (A) Sagittal proton MRI image composite of the 4-well chip containing a 0.5%, 1%, 2% or 5% CMC cryogel in each well (from left to right). (B) Horizontal pixel sum of each well ROI from panel (A) . (C) Well region without scaffold (T ROI) pixel intensity normalised by the total one (T ROI + B ROI) for three experiments containing a 0.5%, 1%, 2% or 5% CMC cryogel in each well injecting D\(_2\)O at different flow rates (0.1, 1 and 5 mL/min). (D) Normalised T ROI for an experiment containing one or two 1% CMC cryogels in each well injecting D\(_2\)O at 5 mL/min. (E) Normalised T ROI pixel intensity for an experiment containing two 1% or one 5% CMC cryogels in each well injecting D\(_2\)O at 0.1 mL/min.
