钼铑双靶X线对乳腺导管内癌及微小浸润导管内癌的诊断价值

Value of Molybdenum and Rhodium Twin Target X-ray in Diagnosis of Breast Ductal Carcinoma in Situ and Intraductal Carcinoma with Micro-invasion

目的探讨钼铑双靶X线检查对乳腺导管内癌(DCIS)与微小浸润导管内癌(DCIS-MI)诊断及鉴别诊断价值。方法回顾性分析经病理证实的10例DCIS与6例DICS-MI患者的钼铑双钯X线片特征。结果 DCIS X线征象:①多发细小钙化5例,钙化范围局限;②局限性致密、结构不良7例,边缘部分清楚;③间接征象:伴有乳头凹陷1例,血运较对侧丰富1例,腋下见致密增大淋巴结影2例。DCIS-MI X线征象:①多发细小钙化4例,范围较广泛,钙化形态不规则,见模糊的钙化影;②局限性致密、结构不良2例,边缘不清;③间接征象:伴有乳头凹陷1例,2例皮肤有增厚,腋下见致密增大淋巴结影1例。结论肿块或局限性致密与多发细小钙化为DCIS及DCIS-MI最常见X线表现形式。对钙化的分析有利于术前判断病变是否浸润,有利于临床制定手术范围及手术方式的制定。

Objective To evaluate the value of molybdenum and rhodium twin target X-ray diagnosis and differential diagnosis of the breast ductal carcinoma in situ（DCIS） and intraductal carcinoma with micro-invasion（DCIS-MI）.Methods Retrospective analysis X-ray imaging of 10 cases of DCIS patients and 6 cases of DCIS-MI patients,which confirmed by pathologically.Results X-ray of DCIS：①Five cases were featured micro-calcification,calcification confined;②Seven cases were featured with increased density or structural disorder.③Indirect signs：one case associated with inverted nipple,another rich blood supply than the contra lateral one case,and the axillary lymph node density increases in two cases.DCIS-MI X-ray：①Multiple small calcifications in four cases,the broader,irregular calcification,calcification blur;②Only showed local density or structural disorder in two cases,blurred edge;③Indirect signs：Inverted nipple in one case,two cases of skin thickness,and the axillary lymph node density increases in one case.Conclusion Dense mass or limitation and multiple small calcifications are DCIS and DCIS-MI X-ray the most common form.Analysis of the calcification disease help determine whether preoperative infiltration is beneficial to the scope of clinical surgery and surgical methods to determine the formulation.
