Figure 1a. (a) Precontrast radial color power Doppler US image of a primary breast cancer shows central (open arrows) and peripheral (solid arrows) vessels. (b) Postcontrast radial color power Doppler US image of the same lesion as in a shows an increase in central (open arrows), peripheral (solid arrow), and side-branching (arrowheads) vessels.

Figure 3a. (a) Precontrast radial color power Doppler US image of a benign axillary node shows a single central perhilar vessel (arrow). (b) Postcontrast radial color power Doppler US image of the same lesion as in a shows an increase in central perhilar (long thin arrows), central (short arrow), and peripheral (long thick arrows) vessels.

Figure 4a. (a) Precontrast radial color power Doppler US image of a malignant axillary node shows central (open arrow) and peripheral (solid arrow) vessels. (b) Postcontrast radial color power Doppler US image of the same lesion as in a shows a florid increase in central (arrows) and peripheral (arrowheads) vessels. (c) Precontrast radial color power Doppler US of the corresponding breast cancer in the same patient as in a shows a solitary tiny vessel (arrow) outside of the lesion. (d) Postcontrast radial color power Doppler US image of the same lesion as in c shows a moderate increase in the number of peripheral vessels (arrows). This increase is markedly lower than the increase in peripheral vessel number in the axillary node seen in b.

Figure 5a. (a) Graph illustrates results of receiver operating characteristic analysis of the postcontrast peripheral vessel numbers in 86 breast masses, for classification of benign and malignant disease. The area under the curve is 0.77, and the optimal cutoff value is four postcontrast peripheral vessels. (b) Graph illustrates results of receiver operating characteristic analysis of the combined score for increase in peripheral vessel number and duration of enhancement in 32 axillary lymph nodes, for classification of benign and malignant disease. The area under the curve is 0.86, and the optimal score is 0.41.
