This work demonstrated that MOCCO can provide high temporal fidelity including robustness to recover different temporal enhancement curves for quantitative analysis in the setting of breast DCE-MRI.
Figure 4. Visualization of error maps of (A) Ktrans = 0.133, 0.399, 0.666, 1.602 min-1 and Ve = 0.3 obtained by measuring the % differences between the fitted parameters and the true values (% error) for the lesion region depicted in (B). Red and blue represent the level of overestimation and underestimation, respectively.
Figure 2: Simulated contrast agent concentration uptake curves (displayed for a subset of time from 150 s to 400 s). Mean concentration for eight lesions with varying pharmacokinetics reconstructed using MOCCO (A-H, red squares). Standard deviations are shown with banded areas. The input time curves (“truth”) used to generate the source data are plotted in black for all frames.
