A Novel Approach to the Evaluation of Breast Masses Using Doppler Ultrasonography: Percentage Changes in Resistive Index Between the Mass and Surrounding Normal Parenchyma in Benign-Malignant Differentiation

The aim of this study is to reveal the role of differences in the resistive index of masses and surrounding tissue in distinguishing between benign and malignant masses using a new approach in the evaluation of breast masses with Doppler ultrasound. The minimum, maximum, and average RI values obtained from the mass and healthy breast tissue will be recorded. The relative RI value difference will be calculated from the RI values of the mass and healthy tissue. Based on the pathology results, the cases will be divided into two groups: benign and malignant. The threshold values of these values in malignant and benign masses will be determined and compared. Additionally, vascular index values in breast masses will be calculated and compared using the relatively new Doppler Microvascular Flow method.
