Figure 1. (a) Dynamic MRI sequences of the right breast after intravenous bolus injection of gadolinium. Serial T₁ weighted gradient echo sequences before and 1 min, 2 min, 3 min and 6 min after gadolinium-DTPA intravenous bolus injection. Subtraction of pre-contrast from early post-contrast images shows a single 16 mm early contrast nodular enhancement before RFA. Its location is distant to the overlying skin, to the nipple area and to the pectoralis muscle. (b) MRI (sequence T₁) at 1 month. Note the 50 mmx35 mm well-defined hypointense area delineated by a tiny contrast enhancement at the periphery, which is supposed to correspond to reactive granulation tissue around the avascular treated area.
