Synthetic MRI parameters can be used as quantitative imaging biomarkers for the different receptor status of breast cancer. SD of PD-Pre, SD of PD-Gd, T2-Pre and T2-Gd were significantly different among molecular subtypes.
Figure 1: A 58-year-old woman with invasive ductal carcinoma of the right breast. An example of the synthetic images obtained before contrast agent injection. (a) T2(synthetic); (b) PD map; (c) T1 map; (d) T2map. The ROI showed the quantifications: T1-Pre = 1.71 10-3ms, SD of T1-Pre = 0.19, T2-Pre = 80.00 ms, SD of T2-Pre = 4.00, PD-Pre = 59.00 pu and SD of PD-Pre = 2.50 in this ER-positive, PR-negative, HER2-negative and Ki-67 high proliferating tumor.
Note. Data are mean ± standard deviation. P values less than .05* were considered to indicate statistical significance.
