1、数字化相位对比乳腺摄影临床应用探讨［摘耍］冃的：探讨相位对比乳腺钥靶成像技术特点及临床应用价值。方法：应用日本REGIUSPureViewM型相位对比乳腺成像系统,2010年厂12月共检查患者1173例,双侧乳腺对比检查，投照体位均包括侧斜位和轴位，釆用多中心电离室控制全H动曝光，曝光千伏26~34kV,毫安秒29^117mAso结果：双侧乳腺轴位及侧斜位对称显示，图像质量均符合乳腺摄影质量控制合格标准，乳房皮肤、皮下脂肪、乳腺、胸大肌及腋窝组织等不同组织结构均衡清晰显示，对致密型乳腺内0.T0.2mm微小钙化灶显示清晰。X线曝光剂量较低。经
2、手术病理证实恶性肿瘤47例，其屮，女46例，年龄24〜88岁，平均53.13岁，右侧22例，左侧26例；男性1例,55岁,左侧。良性肿瘤72例,均为女性,年龄19~70岁，平均40.88岁，右侧41例，左侧40例，双侧病灶者9例。结论：相位对比乳腺成像技术影像学特点突出，为乳腺癌诊断和鉴别诊断提供可靠依据。［关键词］乳腺X线摄影术；相位对比［中图分类号］R445［文献标识码］B［文章编号］1673-7210(2011)12(b)-106-03Clinicalapplicationresearchofphase-contrastmammogra
