To compare findings from first imaging follow-up mammography for breast lesions shown to be benign at stereotactic biopsy with 14-gauge automated needles or 14-gauge directional, vacuum-assisted probes.
In 495 stereotactic breast biopsies, the mammographic appearance of the biopsy site or target lesion was evaluated at first imaging follow-up with a four-point scale (1 = progression of lesion or suspicious interval change [repeat biopsy], 2 = no clinically relevant change, 3 = interval decrease in size of lesion or number of microcalcifications, and 4 = no residual mammographic lesion). An automated needle was used in 363 biopsies and a directional, vacuum-assisted probe was used in 132 biopsies. Patient and lesion variables and time to first imaging follow-up were compared for the two techniques.
No biopsy site or target lesion was assigned a score of 1 at first imaging follow-up with either technique. No lesion was referred for repeat biopsy because of the mammographic appearance at first imaging follow-up. First imaging follow-up was performed an average of 6.6 months for the directional, vacuum-assisted biopsies and 8.6 months for the automated needle biopsies (P < .0001). This difference reflected a difference in scheduling methods.
Directional, vacuum-assisted and automated needle breast biopsies produced no distortion or suspicious interval change at the biopsy site at the first follow-up mammographic examination.
比较在立体定向活检中使用14号自动活检针或14号定向真空辅助探头显示为良性的乳腺病变的首次乳腺成像随访结果。
在495例立体定向乳腺活检中，在首次成像随访时用四点量表评估活检部位或目标病变的乳腺X线表现（1 =病变进展或可疑的间期变化[重复活检]，2 =无临床相关变化，3 =病变大小或微钙化数量的间期减小，4 =无残留乳腺X线病变）。363例活检使用自动活检针，132例活检使用定向真空辅助探头。比较两种技术的患者和病变变量以及首次成像随访时间。
两种技术在首次成像随访时，均无活检部位或目标病变被评为1分。没有病变因首次成像随访时乳腺X线表现而被转诊进行重复活检。定向真空辅助活检的首次成像随访平均在6.6个月进行，自动活检针活检在8.6个月进行（P <.0001）。这种差异反映了 scheduling方法的不同。
在首次随访乳腺X线检查时，定向真空辅助活检和自动活检针活检在活检部位均未产生变形或可疑的间期变化。
