  • a Each entry represents the AUC±SE of a combination of parameters mentioned in the respective rows and columns. Values in parentheses represent AUC±SE of that particular parameter or combination. Blank cells are left to avoid repetition of values.

  • b A combination of FDG-PET and MR imaging parameters has a better AUC±SE than a combination of MR imaging parameters.

  • c Note that the maximum AUC was achieved with a combination of ADCmean, Cho/Cr, and TBRmean.
