  		Fig. 1 —Interpretation method of non-masslike enhancement. First, distribution patterns were classified into three categories (single quadrant/solitary lesion, single quadrant/grouped lesion, and multiquadrant lesion). Second, presence of ductal pattern was assessed in enhancing lesions. Third, internal enhancement was evaluated. Fourth, in addition to BI-RADS MRI descriptors, presence of clustered ring enhancement was also assessed in heterogeneous enhancing lesions (positive or negative).

  		Fig. 3 —51-year-old woman who presented with bloody nipple discharge of right breast. Coronal first contrast-enhanced T1-weighted MR image shows linear-ductal enhancement in upper outer quadrant (arrows). Craniocaudal and transverse lines are drawn crossing over nipple. Note clumped internal architecture. Histologic evaluation of lumpectomy specimen revealed atypical ductal hyperplasia.

  		Fig. 4C —47-year-old woman with microcalcifications on mammography. Histologic evaluation of lumpectomy specimen revealed ductal carcinoma in situ (DCIS). Branching ductal pattern corresponded to DCIS (arrows) with surrounding atrophic tissue.

  		Fig. 5B —53-year-old woman with palpable nodule of right breast. No abnormalities were seen on mammogram. Transverse multiplanar reconstruction of first contrast-enhanced T1-weighted MR image shows nonbranching pattern with clumped internal architecture (arrows).

  		Fig. 5C —53-year-old woman with palpable nodule of right breast. No abnormalities were seen on mammogram. Histologic evaluation of mastectomy specimen revealed ductal carcinoma in situ (DCIS). Clumped internal architecture corresponded to clusters of multiple ducts enclosed with fibrous stroma (arrows).

  		Fig. 6B —54-year-old woman with palpable nodule of left breast. Transverse third contrast-enhanced T1-weighted MR image at 4 minutes shows nonbranching, heterogeneous enhancement (arrows). Note clustered ring enhancement. Histologic evaluation of mastectomy specimen revealed ductal carcinoma in situ (DCIS).
