【摘要】 目的:评价X线立体定位活检对乳腺微小病变的诊断价值。方法:采用计算机辅助三维立体定位系统、弹射式活检枪和16G活检针,对31例X线发现的乳腺可疑病变灶直接立体定位穿刺活检。其中24例随后行外科手术,穿刺活检与手术活检的病理结果对照。结果:24例中乳腺癌8例(33.3%),良性病变16例(66.7%),诊断符合率为87.5%,误诊3例(12.5%)。结论:X线立体定位活检是鉴别乳腺微小病变良恶性的有效方法,有助于早期发现乳腺癌。更多还原

【Abstract】 Objective: To assess the value of X-Ray stereotactic core needle biopsy(SCNB) in diagnosis of mammographic minimal lesions.Methods: Thirty-one cases with suspicious malignant lesions detected by mammography underwent breast biopsy using computer-assisted stereotactic system with spring-loaded biopsy guns and 16G core needles.All specimens underwent histopathologic examination.Surgical operations were performed in 24 cases after SCNB,and pathological findings of SCNB specimens were compared with those of surgical biopsy.Results: Among 24 cases with surgical excision,8 cases(33.3%) were confirmed as breast carcinoma,and the other 16 cases(66.7%) was benign breast lesions.The consistence rate of diagnosis with two methods was 87.5%.Conclusion: As a safe and effective diagnostic method,SCNB is preferred approach to differentiate between malignant and benign diseases of minimal breast lesions before surgery.更多还原
