A 38-year-old woman with breast cancer on preoperative magnetic resonance imaging for staging. (A) Sagittal, contrast enhanced T1-weighted image showing oval, smooth, heterogeneous enhancing mass in the right breast, measuring 6 mm, which was categorized into American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) category 4a. (B) Dynamic time-intensity curves of the lesion showing an initial fast uptake followed by a fast washout in the delayed phase (type III), which was categorized into BI-RADS category 4a. (C) Sagittal, contrast enhanced T1-weighted image on the day of biopsy showing no suspicious lesions, and hence magnetic resonance imaging-guided breast biopsy was cancelled.
