Figure 4a:

Plots show the comparison of graft size according to cardiac CEST imaging and histologic findings. (a) The quantification of graft size measured as a percentage of left ventricular (LV) myocardial area according to cardiac CEST imaging across all mice in which Eu-HP-DO3A cells were implanted demonstrated association with corresponding histologic measurements. (b) Bland-Altman analysis demonstrated close agreement in graft size, with slight underestimation of graft size according to MR imaging in grafts larger than 12% of left ventricular area.
