From: Can DWI-MRI be an alternative to DCE-MRI in the diagnosis of troublesome breast lesions?
A 54-year-old female came for follow-up after mastectomy. Mammography (A) showed left breast cluster of microcalcification, and ultrasound (B) showed left 12 o’clock hypoechoic lesion with irregular outline. Sonomammography revealed BIRADS 4. MRI axial images showed left upper central ill-defined area with intermediate signal on T1 (C) and T2 (D). MRI axial dynamic THRIVE sequence and subtraction image (E) showed left upper central heterogeneously enhanced mass. Time/signal intensity analysis of ROI (F) showed rising curve pattern (type I) with SI% of 137%. Diffusion sequence b 850 (G) and post-processing ADC map (H) showed restricted diffusion. ADC value for ROI was 0.8 × 10−3 mm2/s. DCE-MRI revealed suspicious morphology and benign curve BIRADS 4 and DWI-MRI revealed suspicious findings BIRADS 4. Pathology revealed invasive duct carcinoma
