This study aimed to compare the accuracy of sonography versus digital breast tomosynthesis to locate intramammary marker clips placed under ultrasound guidance. Fifty patients with suspicion of breast cancer (lesion diameter less than 2 cm [cT1]) had ultrasound-guided core needle biopsy with placement of a marker clip in the center of the tumor. Intramammary marker clips were subsequently located with both sonography and digital breast tomosynthesis. Sonography detected no dislocation of intrammammary marker clips in 42 of 50 patients (84 %); dislocation was reported in 8 patients (16 %) with a maximum dislocation of 7 mm along the x-, y- or z-axis. Digital breast tomosynthesis showed accurate placement without dislocation of the intramammary marker clip in 48 patients (96 %); 2 patients (4 %) had a maximum clip dislocation of 3 mm along the x-, y- or z-axis (p < 0.05). The use of digital breast tomosynthesis could improve the accuracy when locating intramammary marker clips compared to sonography and could, in future, be used to complement or even completely replace sonography.
本研究旨在比较超声与数字乳腺断层合成技术在定位超声引导下放置的乳腺内标记夹方面的准确性。50例疑似乳腺癌患者（病变直径小于2 cm [cT1]）接受了超声引导下的粗针穿刺活检，并在肿瘤中心放置了标记夹。随后分别用超声和数字乳腺断层合成技术定位乳腺内标记夹。超声检查发现，50例患者中有42例（84%）的乳腺内标记夹无移位；8例患者（16%）报告有移位，沿x、y或z轴的最大移位为7 mm。数字乳腺断层合成技术显示，48例患者（96%）的乳腺内标记夹放置准确无移位；2例患者（4%）的标记夹沿x、y或z轴的最大移位为3 mm（p < 0.05）。与超声相比，使用数字乳腺断层合成技术在定位乳腺内标记夹时可提高准确性，未来可用于补充甚至完全替代超声检查。
