They performed power and duplex color doppler sonography in breast lesions to evaluate lesion vascularity, pi and ri of the vessels, and correlated with histologic results. Although color flow was more frequently seen in malignant than in benign lesions, the sensitivity, specificity, and positive- and negative-predictive values for this sign. Power doppler vf imaging is a valuable adjunct tool to b-mode sonography in the evaluation of breast lesions. Key words breast sonogra-phy doppler sonography ultrasound technology. Evaluation of solid breast lesions with power doppler value of penetrating vessels as a predictor of malignancy. The presence of calcification in the breast lesion and the margin, shape and posterior acoustic features of the lesion were significant parameters in predicting malignancy (p 0.). Breast cancer, the most common cancer in the womens population, is the second mortality cause of cancer in this group and the most important mortality factor among women aged 45-55 years. 1,2,3these statistics emphasize the necessity of screening and early diagnosis of breast cancer. This study aimed to evaluate the vascular pattern of solid breast lesions using power doppler ultrasonography (pdus) and assess whether the presence of intratumoural penetrating vessels can predict breast cancer malignancy. The presence of calcification in the breast lesion and the margin, shape and. The transducer upright to the lesion and breast wall in terms of not to impede the spreading fremitus effect. Con- cerning only the power doppler fremitus acquisition time, the examination took 3 - 5 minutes (mean 3.).   purpose to evaluate power doppler ultrasonography (us) performed with a microbubble us contrast agent in the differentiation of nonpalpable breast lesions. Materials and methods fifty nonpalpable breast lesions in 50 patients were prospectively evaluated with power doppler us before and after injection of the contrast agent sh u 508a. Purpose to evaluate power doppler ultrasound (us) in detection of vascularity of solid breast lesions and to correlate patterns of vascular distribution with histopathologic findings. Materials and methods eighty-six solid breast masses, which were subsequently sampled for biopsy, were studied with gray-scale and power doppler us. Power doppler vocal fremitus test (pdvft) is a method that depends on the theory of the distinctive color aliasing patterns which can theoretically be used to differentiate benign and malignant lesions. In this study, differently from previously published but limited data, the the color. Materials and methods we performed a phantom study using a lesion-in-breast model, investigating the concept that the flash artifact is induced at the tip of the vibrating needle on power doppler images, before attempting any clinical applications. In view of the results achieved in the phantom study, we applied this technique to patients.
