金属定位在乳腺钼靶X线导丝定位术中的应用价值

目的研究金属定位在乳腺钼靶X线导丝定位术中的应用价值。方法本组共48例，术前钼靶X线照射诊断簇状钙化28例，结构紊乱及结节样病变20例。根据先行乳腺钼靶片，放置金属标记物在钙化或结节区域，摄片核准位置后作上标记，之后使用专用乳腺痛变定位设备，对作有标记的痛变部位进行左右15°定位照射，专用设备上读取病变中心点确定穿刺部位，穿刺后再次摄片确定导丝是否到达痛变位置：手术后对切除组织进行摄片，确定痛变部位是否完全切除，而后送病理科检验，结果经金属定位与乳腺钼靶X线导丝定位术结合后，病变切除率100％，病理结果为纤维瘤12例，乳腺癌23例，原位癌6例，乳腺增生痛7例。结论金属定位在乳腺钼靶X线导丝定位术中的应用具有可行性，简单方便，可在临床推广.

Objective To study the application value of metal positioning in the technique of mammographic wire-localization. Methods A total of 48 cases, by preoperative molybdenum target X-ray irradiation, 28 cases were diagnosed with clusters of calcification, 20 cases were diagnosed with structure disorder and nodular lesions. According to the breast mammography, metal markers were placed in calcification or nodule areas, then marking the spot after the position was approved. Dual 15 ° stereo-mammography localization of the lesions was undertaken with a dedicated breast lesions positioning equipment. The center of the lesion was determined as puncture site. Radiography was taken again after puncture positioning to determine whether the wire undertaken the lesion area. Mammogram of the resected specimen was again undertaking after surgical resection to confirm whether the lesion was completely removed, and then send the specimen for pathology inspection. Results Through metal positioning combined with mammographic wire-localization technique, the lesion resection rate was 100%. The pathological results： 12 cases fibroma, 23 cases of breast cancer, 6 cases of carcinoma in situ, 7 cases of mammary gland disease. Conclusions The application of metal positioning in mammographic wirelocalization technique is feasible, convenient and can be popularized in clinical.
