在数字钼靶环境下探究早期乳腺癌影像特点【摘要】 目的 提高钼铑双靶X线对早期乳腺癌诊断的准确性。方法 对41例经手术及病理证实早期乳腺癌X线征象进行回顾性分析。结果 早期乳腺癌征象:结节状肿块23例;钙化17例,X线未见明确肿块或结节而钙化灶为惟一恶性征象2例;非对称性密度增高12例;局限性皮肤增厚伴乳头凹陷2例。结论 ①肿块是早期乳腺癌重要的诊断依据;②微细钙化仍是早期乳腺癌重要的诊断依据,甚至比直接征象(肿块)更具特异性;③非对称性局限性致密、乳腺结构局部扭曲紊乱,在排除炎性反应和手术史后,应考虑乳腺癌可能;④除恶性钙化外,大于两种间接征象并存时,应高度重视,予以进一步检查或短期复查。 【关键词】 早期乳腺癌;钼铑双靶摄影;诊断 Molybdenum Target in the digital environment,to study the image characteristics of early breast cancer ZHAO Tie-Zeng. Second Affiliated Hospital Qiqihar Medical College of Radiology,161000,China 【Abstract】 Objective To improve the pairs of molybdenum and rhodium target X ray of early breast cancer diagnostic accuracy. Methods 41 cases confirmed by surgery and pathology of early breast cancer X-ray findings were analyzed retrospectively. Results signs of early breast cancer: 23 cases of nodular masses; calcification in 17 cases, X ray no clear lumps or nodules and calcification of the only 2 cases of m alignant signs; non-symmetry of high density 12; limitations associated with skin thickening nipple retraction in 2 cases. Conclusion ①mass is an important basis for the diagnosis of early breast cancer;②micro-calcification is still an important basis for the diagnosis of early breast cancer, even more than the direct signs of (mass) more specific;③non-symmetry of the limitations of dense breast structure of local distortions disorders, inflammation and surgical history of the exclusion, it should be possible to consider breast cancer;④In addition to m alignant calcification, the more than two kinds of indirect signs of co-exist, we should attach great importance to be further examination or short-term review. 【Key words】 Early breast cancer;Rh-Mo double-target PhotographyDiagnosis 随着人们生活水平的日益提高,女性对生育、哺乳观念的改变,乳腺癌的发病率正逐年提高。在乳腺癌的诊治过程中,乳腺癌发现的早晚,直接影响到治疗和预后,因此,乳腺癌的早期发现和诊断成为治疗和预后的关键。 数字化乳腺钼靶摄影是早期乳腺癌诊断的首要诊断方法,对于判定预后及是否适合保乳手术等具有重要意义和参考价值。笔者收集本院41例早期乳腺癌的临床资料及术前较完整的钼靶影像资料进行分析,总结其X线特征,以便在今后工作中提高对早期乳腺癌认识和诊断水平。 1 资料与方法 1.1 一般资料 从2003年7月至
