1、低场MR对乳腺癌诊断价值【摘要】目的评估低场MR对乳腺癌的表现和诊断价值。方法收集本院近3年间(2005年5月至2008年6月)资料完整的乳腺MRI检查并经手术(或穿刺)后病理证实的乳腺癌患者40例作为研究对象,对其临床资料及MRI等影像表现进行回顾性分析。结果患者均为女性,年龄38~86岁,平均49岁,大多数为浸润性导管癌(20例)及髓样癌(16例),只有4例为浸润性特殊型癌,黏液腺癌,本组研究显示MRI对乳腺癌诊断的敏感性、特异性和准确性分别为98.6%、86.5%、89.5%。结论乳腺癌的MRI表现较有特异性,MRI为乳腺癌的诊断和鉴别诊断提供了一种安全有效的影像学手段,特别是MR
