Fig. 1. Axial contrast-enhanced T1-weighted subtraction MR images obtained 150 s after contrast injection in a 49-year-old premenopausal woman treated for contralateral invasive ductal carcinoma. (a) Baseline image before treatment with tamoxifen obtained with 1.5T MRI system shows moderate BPE. (b) After 22 months from baseline study, follow-up 3.0T MR image during treatment with tamoxifen shows a decrease to minimal background parenchymal enhancement. Fig. 1.
