nancies to grayscale and power Doppler imaging, with and without contrast administration, and to mammography. Methods: Thirty-three patients with breast lesions, who subsequently underwent a breast biopsy, participated in a study of mammography and contrast-enhanced ultrasound. Optison (Mallinckrodt, St. Louis, MO) was administered intravenously (dose: 1 ml). Grayscale ultrasound, pre and post contrast power Doppler and grayscale PIHI of the lesion were obtained using an HDI 3000 scanner (Philips Medical Systems, Bothell, WA) and a high-frequency linear array. Two independent and blinded readers assessed diagnosis on a six-point scale ranging from no lesion to malignant. Logistic regression was used to combine mammographic and ultrasound findings. The area under the receiver operating characteristic (ROC) curve was computed individually and in combination for mammography, PIHI as well as ultrasound (pre and post contrast). The areas were compared using Mann-Whitney statistics. Results: Biopsy findings were available for 33, mammography for 30 subjects, and ultrasound imaging for 32, respectively. Eleven (33%) had malignant breast lesions. Mammography achieved a sensitivity of 100%
