Impact of Different Analytic Approaches on the Analysis of the Breast Fibroglandular Tissue Using Diffusion Weighted Imaging

Figure 3

Correlation of the percent density (PD) with ADC measured using four different methods. (a) ADC measured from the whole breast () shows a high correlation with PD, with . (b) ADC measured from the segmented fibroglandular tissue in the whole breast () shows a moderate correlation with PD, with . (c) ADC measured from the segmented fibroglandular tissue in a single central slice () shows a moderate correlation with PD, with . (d) ADC measured from a small manually placed ROI () shows a weak correlation with PD, with . From (a) to (d), as the fat content decreases, the ADC increases and shows worse and worse correlation with the whole breast PD.
