数字乳腺摄影诊断乳腺良恶性肿块的价值及误诊分析

摘要

Objective :To assess differentiation of benign between malignant breast tumors by digital mammography . Methods :80 patients were enrolled during Decernber 2012 to Decernber 2015 ,which were all underwent mammogra‐phy .The follow‐up of benign ended until June 2016 .The digital mammography were assessed according to BI‐RADS categories .Results:(1)In 80 patients ,88 lesions including 35 malignant lesions and 53 benign lesions were found .The average age of the malignant and benign lesions were 46 .36 ± 9 .816 and 40 .45 ± 8 .216 respectively ,the malignant group is elder than the benign group ,the discrepancy has statistic significance(P<0 .05) .(2)The sensitivity ,specifici‐ty ,the fake positive rate and the fake negative rate were respectively 80 .0% ,88 .7% ,11 .3% and 20 .0% for mammog‐raphy .(3)Mammography performances of 88 lesions are shown as local increased density (26 ,29 .5% ) ,pure lump(20 , 22 .7% ) ,pure calcification(18 ,20 .5% ) ,lump with calcification(20 ,22 .7% ) ,architectural distortion(4 ,4 .5% ) .Conclu‐sion:Digital mammography has important value in differentiating benign and malignant breast tumors ,but there is still a certain amount of misdiagnosis and ,if necessary ,should be combined with ultrasound or MRI examination .%目的：评估数字乳腺摄影鉴别乳腺良恶性肿块的价值。方法：收集2012年12月－2015年12月在我院行数字乳腺摄影80例女性患者，良性病例随访截止至2016年6月，采用BI‐RADS分类评价数字乳腺摄影的检查结果，并与病理作对照。结果：80例患者共检出88个病灶，其中恶性35例，良性53例。（1）乳腺恶性肿块组平均年龄为（46.36±9．816）岁，良性组平均年龄为（40．45±8．216）岁，恶性组年龄高于良性组，差异有统计学意义（ P＜0．05）。（2）数字乳腺摄影的敏感性为80．0％，特异性为88．7％，假阳性率为11．3％，假阴性率为20．0％。（3）88个病灶数字乳腺摄影表现分别为局部密度增高26例（29．5％），单纯肿块20例（22．7％），肿块伴钙化20例（22．7％），单纯钙化18例（20．5％），结构扭曲4例（4．5％）。结论：数字乳腺摄影鉴别乳腺良恶性肿块有重要的价值，但仍然存在一定的误诊，必要时需结合超声或M RI检查。
