(a) R1ρ map at 545 Hz for glucose and uracil samples of specified concentrations. (b) The entire R1ρ dispersion of each sample shown on the R1ρ map. (c) Exchange rate contrast (ERC) map at 545 Hz of the same samples; note the increased intensity of the 200 mm glucose sample as a result of the dependence on exchange rates, not relaxation rates. (d) Mean ERC values of each sample calculated by region of interest (ROI) analysis over each specific sample. PBS, phosphate-buffered saline.
