摘要
目的分析钼靶X线检查假阴性的乳腺癌的影像学特点,探讨假阴性的原因。方法回顾性分析2011年6月—2013年6月辽宁医学院附属第一医院乳腺外科乳腺钼靶X线检查为阴性,但经手术病理证实为乳腺癌的79例患者的X线影像学特点,分析钼靶X线检查假阴性的原因。结果 79例乳腺癌患者经钼靶X线检查呈阴性的原因:病灶综合因素占44.3%(35例)、患者自身因素占22.8%(18例)、诊断因素占19.0%(15例)、投照技术因素占13.9%(11例)。结论乳腺癌钼靶X线假阴性与乳腺致密程度、患者年龄、肿瘤直径与位置相关,多为浸润性。提高诊断医生对乳腺癌钼靶X线征象的认识,增强诊断医生和技师的责任心,可减少乳腺癌X线诊断的假阴性。
Objective To analyze the imaging features of X -ray mammography for false -negative breast cancer （ BC）to explore its reasons. Methods The features of X-ray images of 79 patients from the First Affiliated Hospital of Liaon-ing Medical University in June 2011 to June 2013 who had negative results by mammography but were diagnosed as BC by opera-tive and pathological findings were analyzed retrospectively to find the reasons for the false negative results. ResUlts The reasons for the negative X-ray mammography results were composite factors of lesions（35 cases,accounting for 44. 3%）,patientsˊown factors（18 cases,accounting for 22. 8%）,diagnostic factors（15 cases,accounting for 19. 0%）,technical factors of projection（11 cases,accounting for 13. 9%）. ConclUsion BC X -ray mammography false negative results are related to breast density,age,tumor sizes and location,most of which are infiltrating. Improvement of physiciansˊ awareness of X-ray mammography signs can reduce false-negative diagnoses.
