MRI已经成为乳腺癌筛查的重要手段,其优点为无创无辐射、软组织对比分辨率高、任意方向直接切层,然而常规磁共振检查对乳腺癌检出敏感性高但特异性低,导致很多的误诊漏诊。本研究将DWI与动态增强扫描相结合,联合诊断乳腺良恶性病变。一、资料与方法1.临床资料:对2009年9月至2011年3月中山大学肿瘤防治中心经手术病理证实的29例乳腺癌患者进行回顾性MRI
MRI has become an important tool for breast cancer screening. The advantage of this method is noninvasive and non-radiation. Soft tissue contrast resolution is high and it is directly sliced in any direction. However, conventional magnetic resonance imaging has a high sensitivity but a low specificity for detecting breast cancer. Misdiagnosis missed diagnosis. This study combined DWI with dynamic contrast-enhanced scanning in the diagnosis of benign and malignant breast lesions. First, the data and methods 1 clinical data: from September 2009 to March 2011 Sun Yat-sen University Cancer Center confirmed by surgery and pathology of 29 cases of breast cancer patients with retrospective MRI
