MRI Texture Analysis of Background Parenchymal Enhancement of the Breast

Figure 1

A 32-year-old woman with fibroadenoma. Background parenchymal enhancement (BPE) of the right breast is scored as moderate, while that of the left breast is scored as mild. Texture analysis (TA) reveals that the variance of signal intensity (SI) is 356.7 for the right breast and 310.5 for the left breast. A fibroadenoma is hyperintense to BPE (arrows).
