DW images of lesions graded as 1, 2, 3, 4, and 5 point based on the appearance and signal strength of lesions compared with surrounding breast parenchyma. (a) Grade 1 with symmetric signal intensity of bilateral breast. (b) Hyperplasia lesion in left breast scored as 2 with regional distribution, indistinct margin and moderate signal. (c) Fibroadenoma in left breast (arrow) scored as 3 with circumscribed appearance, definite margin and moderate signal. Another hyperintensity lesion is a cyst, which was not included in the study.
