Fig. 4: Compositional heat maps of all lesion pathologies.

Each row consists of a lesions with a different pathology. a–d contain benign lesions, e–h contain fibroadenomas, i–l contain ductal carcinoma in situ (DCIS), and m–p contain invasive lesions. The first column (a, e, i, m) contains the standard mammogram presentation, the second (b, f, j, n), third (c, g, k, o), and fourth (d, h, l, p) columns contain the corresponding three-compartment breast (3CB) LWP thickness map. Colorbars adjacent to each 3CB map indicate thickness in centimeters where red indicates areas of high thickness and thickness decreases towards the color violet. Thickness ranges are normalized across each column. Yellow lines are radiologist delineations of where biopsies were taken from which lesion pathology was determined.
