Sensitivity of BCa DCE-MRI PK analysis to delay between AIF and TRF: patient #16, visit1. ${\mathrm{BAT}}_{\mathrm{A}\mathrm{I}\mathrm{F}}$ was provided as population averaged: (a) Illustration of concentration curves for population averaged AIF (red dotted line), the mean (blue solid line) for 5147 TRF curves in the TROI. (b) 2-D axial image showing delineated tissue ROI on DCE-MRI image. (c–e) boxplots of (c) $K^{\mathrm{trans}}$, (d) $v_{\mathrm{e}}$, and (e) $R^2$ at different BAT_TRF timepoints with the same BAT_AIF (timepoint unit: DCE-MRI $\text{sampling rate}=18.17\mathrm{s}$).
