The results are presented as medians, 25th percentiles, and 75th percentiles. The P values are for the nonparametric test results of the morphology and textural features of 40 PTs and 290 FAs. Values in italic denote statistically significant features. PTs, phyllodes tumors; FAs, fibroadenomas; Cir, circularity; HWR, height-to-width ratio; MS, margin spicules; MC, margin coarseness; MI, margin indistinctness; ML, margin lobulation; E, energy; GE, grey entropy; GM, grey mean; IC, internal calcification; ALS, angle between the long axis of the lesion and skin.
