Color Doppler sonography (Toshiba Model SSA-260A, 7.5 MHz) was performed on 145 histologically confirmed breast masses: 71 were benign; 74 were malignant. Both the detection rate and waveform analysis of intratumoral flows were evaluated. Intratumoral flows in malignant tumors (93.2%) were detected at a significantly higher rate (60.6%) than in benign masses (P
