Parallel Artery and Vein: Sign of Benign Nature of Breast Masses

“…Precise semiologic criteria for benign and malignant lesions according to location and morphologic features of the vessels detected have been established [6][7][8][9][10][11][12][13]. The following criteria have 73-98% sensitivity for malignancy and 16-90% specificity [13]: intratumoral vessels without capsular vessels, vascularization of a large percentage of the …”

“…Flow patterns and waveforms are analyzed with spectral Doppler technique, and morphologic features are analyzed with color and power Doppler techniques [2][3][4][5][6][7][8][9][10][11][12][13]. The following elements are described as characteristic of malignancy: more than one vascular pole; abnormal afferent vascularity (tortuous vessels penetrating the tumor); and hypervascularity with irregular, branch-…”
