pH is an important microenvironment parameter, in fact a number of disease states are associated with alterations in pH, such as ischemia, inflammation, infection and cancer, and many kidney injuries are associated with a perturbation of renal pH, therefore imaging techniques able to report in vivo on pH modifications would have a great relevance. The aim of the work was to investigate the use of Iopamidol as a MRI-CEST pH reporter of the disease evolution in glycerol-induced AKI model, exploiting the capability to image pH values in different regions for single kidneys.
