摘　　要：目的探讨乳腺导管内乳头状瘤的钼靶X线及MRI表现及其应用价值。方法对15例经手术和病理证实的乳腺导管内乳头状瘤患者的病例资料进行回顾性分析,其中11例同时行钼靶X线和MRI检查,4例仅作钼靶X线检查。并将MRI图像与钼靶X线表现进行比较。结果MRI图像清晰显示9例导管内乳头状瘤的部位及形态。7例边界光整,2例边缘不规则。肿块T1WI呈等或稍低信号灶,T2WI呈等或稍高信号灶,部分肿块位于囊状扩张的导管内。肿块的血流动力学特点多样,部分与恶性肿瘤难以区分。15例行钼靶X线检查,检出2例(13%)。病灶形态与MRI所见相似,1例病灶所在部位可见沙粒状钙化。结论MRI较钼靶X线能更准确地发现与定位病灶,MRI表现与某些乳腺恶性肿瘤有类似和重叠之处,但仍具有一定特征性。Objective To investigate the features of intraductal papilloma of the breast in mammography and magnetic resonance imaging (MRI) and assess the diagnostic values of the two imaging modalities. Methods Fifteen patients with intraductal papilloma of the breast confirmed surgically and pathologically underwent X-ray examination of the breast, and 11 of them also received enhanced MRI. The imaging findings by mammography and MRI were compared. Results Enhanced MRI clearly displayed the location and morphology o...
