Residual ultrasound lesion characteristics seen on interval follow-up ultrasound imaging (n = 188): For all cases (n = 34), for cases in which an attempt to completely excise the breast lesion was made (n = 19), and for cases in which only diagnostic tissue sampling of the breast lesion was undertaken (n = 15)
