Mammography, ultrasound and Magnetic Resonance Imaging are the available modalities for the evaluation of breast masses. Advances and ongoing improvements in imaging technologies have improved the sensitivity of breast cancer detection and diagnosis, but each modality is most beneficial when utilized according to individual traits such as age, risk factors, and breast density. However, pathological diagnosis is most crucial for the treatment of breast masses. A cross-sectional study were

... ed from January 2017 to April 2018. There were total of 50 patients with clinically diagnosed palpable breast lumps who attended Gynaecological OPD/surgical OPD/medicine OPD in the study period. The patients above 30 years were evaluated by mammography and ultrasound in Department of Radiology, National Academy of Medical Sciences, Bir Hospital. The patients were then send for FNAC/biopsy and histopathology examination. Data were collected and analyzed using SPSS version 16. Specificity and sensitivity of MG and USG individually and in combination to determine the nature of breast lump in relation to histopathological findings were calculated. Ultrasound had 88.90% sensitivity and 68.80% specificity whereas mammogram had 94.40% and 87.50% sensitivity and specificity respectively. When combined, both sensitivity of diagnosing malignant lesions increases up to 94.4% and specificity decreases up to 31.2%. Most of the variables of ultrasound and mammography (except density of the lesion) had significance in predicting nature of the lesion (p< 0.05). Combined Mammography and Ultrasound had higher sensitivity than sensitivity rate observed for either single modality. A combined Mammography and Ultrasound approach to detect breast diseases was significantly more helpful in accurate evaluation of breast pathologies.
