The purpose of this study was to review preoperative CT-guided seed localization in the breast and axilla performed at my institution for lesions not visualized on routine mammography and ultrasound after neoadjuvant chemotherapy. Ten lesions (seven in the axilla, two in the breast, and one in the supraclavicular region) were localized with a radioactive seed under CT guidance. All were successfully excised at surgery, suggesting that CT guidance can be used when needle localization is not feasible using mammography or sonography.
本研究的目的是回顾在我院行新辅助化疗后常规乳腺钼靶和超声检查均未显示的病灶进行术前 CT 引导下乳腺和腋窝穿刺活检的经验。10 例病灶（7 例腋窝，2 例乳腺，1 例锁骨上区域）在 CT 引导下植入放射性粒子。所有病灶均在手术中成功切除，表明当乳腺钼靶和超声引导下穿刺活检不可行时，可以使用 CT 引导。
