Fig. 5. 52-year-old woman with invasive ductal carcinoma with false-positive contrast-enhanced (CE) MRI results after cryoablation.

Fig. 5

A–C, Initial enhanced axial subtraction CE-MR images are shown before (A) and 25 days after cryoablation without (B) and with (C) motion correction postprocessing. Preablation image (A) shows enhancing 14-mm invasive ductal carcinoma (arrow, A). Postablation non–motion-corrected subtraction image shows focal enhancement centrally (arrow, B) within cryoablation area (arrowheads, B), which was interpreted as suspicious for residual carcinoma. Initial subtraction image with motion correction shows apparent resolution of focal enhancement within cryoablation area (arrowheads, C). Apparent enhancement was likely due to misregistration of axial images before and after contrast administration.
