SIGNIFICANCE OF DOPPLER RI AND SYSTOLIC PEAK OF BREAST CARCINOMA LESIONS SEEN ON MAMMOGRAPHY

Abstract

Objective: To analyze the significance of doppler ultrasound and resistive index (RI) and systolic peak to find the breast Carcinoma lesions seen on mammography.

Study Design: Retrospective study.

Place and Duration of Study: Radiology Department of Doctor's Trust Teaching Hospital affiliated with Rai Medical College, Sargodha, from Oct 2018 to Apr 2019.

Methodology: The sample was the women observed with solid breast masses in clinical examination. Those women were 38 in number. The doppler ultrasound was performed on each patient after mammography. Resistive index and systolic peak was also evaluated. Pathology results were also categorized, analyzed and compared with Color Doppler ultrasound.

Results: From the results of Color Doppler ultrasound the vascularity in malignant breast lesions were more as compared to benign lesions. Presence of blood vessels in malignant lesions was 94% and in the benign lesions was 35%. Sharp systolic peak and high systolic velocity was in malignant lesions and low in benign lesions. The malignant lesions and benign lesions mean value of resistive index was 0.70 ± 0.092 and 0.64 ± 0.064. The short
statistical difference was observed p-value 0.060.

Conclusion: The malignancy in ultrasound is predicted with the help of hyper vascularity of the breast lesion. Resistive index and systolic peak is helpful in identifying benign lesion from malignant cases. Mammography results in dense breast are not sensitive therefore doppler sonography is preferred in these cases.
