Background and Objective: After mammogram was introduced, non-palpable breast masses were found. introduced, non-palpable breast masses were found. Therefore, ultrasound-guided core-needle biopsy was also introduced to identify and get sample tissue, instead of open-excisional biopsy. This study aimed to evaluate the accuracy of ultrasound-guided core-needle biopsy compared to open-excisional biopsy. Methods: This was a retrospective descriptive study done in Maharat Nakhonratchasima hostpital breast-masses pati ents, after havi ng both ultrasound-guided core-needle biopsy and openexcisional biopsy. Pathological examination results from both methods were compared. Results: From January, 2012 to July, 2015, there were 91 patients who had been biopsied by both methods. Most abnormal pathologi cal results from ultrasound-guided core-needle biopsy were benign in 68.13%. Cancer-related results were found in 21.98%. 81 patients had results that were in consistent with open-excisional biopsy. Conclusion: In non-palpable breast masses, pathological examination results from ultrasound-guided core-needle biopsy had high accuracy rate of 89.1%(95%CI, 82.58-95.44%), when compared to open-excisional biopsy.
