Figure 3.
Metabolic levels of mI/c-Cr and Lac/Glx within the enhancing volume stratified by clinical status. (A) Box and whisker plots depict that subjects with PsP had higher mean mI/c-Cr and lower Lac/Glx in the enhancing VOI compared to those with true progression. Longitudinal changes in mI/c-Cr and Lac/Glx from PsP to true progression in a single subject are depicted by a black dot connected by a solid line. mI/c-Cr decreased by 56% and Lac/Glx increased by 114% when transitioning from PsP to true progression. The ROC curve for both markers, mI/c-Cr (B), and Lac/Glx (C) is illustrated.
