Abstract
Background: Breast cancer being the most commonly diagnosed malignancy among females, there is a significant role for screening techniques. Mammography and ultrasonography plays a major role in screening and diagnosing lesions of the breast. The number and pattern of vascularization within the lesion helps in differentiating benign and malignant lesions. The present study aims to evaluate the spectral indices in breast pathology
Materials and Methods: Designed as diagnostic test evaluation, among the patients with palpable breast lesions who came for Mammography in department of Radiodiagnosis. Fifty patients were evaluated and the findings were plotted to find out the range of Resistive index (R I), Pulsatility ratio (P I) and Systolic Diastolic ratio (S/D).
Results: RI Values of benign lesions with vascularity was in the range 0.5- to 0.69 and that of malignant lesions of 0.6 to 0. 89. The PI values of malignant lesions were also found to be higher being 1.32 to 1.56 when compared to benign 0.6-1.2. Similarly S/D ratio of benign were 2-3.5 while those of malignant were in the range of 3.5-5.3.
Conclusion: The findings showed that higher RI, PI, and S/D value were more in favour of malignancy
