摘要
目的探讨对比增强能谱乳腺X线摄影(Contrast-enhanced energy spectrum mammography,CESM)针对可疑性钙化的临床价值与意义。方法回顾性研究2017年至2018年常规数字化乳腺X线成像(FFDM)摄影显示有可疑性钙化(诊断报告定义为BI-RADS4类)57例患者资料,均行CESM检查,通过CESM减影图像观察钙化区是否有强化征象,研究此影像特征与病理的相关性,最终以病理结果为金标准,评估出CESM对可疑性钙化的影像学诊断价值和鉴别诊断能力。结果CESM在判断可疑性钙化的敏感度、特异度、阳性预测值、阴性预测值和准确率分别为94.7%(18/19),92.1%(35/38),85.7%(18/21),97.2(35/36),92.9%(53/57)。与病理结果比较差异无统计学意义(=0.000,P=1.00)。结论CESM检查技术对乳腺可疑性钙化有较高的诊断效能,采用此方法获得的影像,对致密性乳腺内钙化病灶的判定,可疑性钙化的穿刺定位,手术前病灶性质的评估等方面,具有准确可靠的临床实用价值。
Objective To explore the clinical value and significance of contrast enhanced energy spectrum mammography( CESM) for suspicious calcification. Methods From 2017 to 2018,a retrospective study of conventional digital mammography( FFDM) photography showed suspicious calcification( diagnostic report defined as BI-RADS4).57 patients were all examined by CESM to observe whether there are signs of enhancement in the calcified area through CESM subtraction images or not.The correlation between this image feature and pathology was studied,and finally the pathological result was the gold standard.The diagnostic value and differential diagnosis ability of CESM for suspicious calcification were evaluated. Results The sensitivity,specificity,positive predictive value,negative predictive value,and accuracy of CESM in judging suspicious calcification were 94. 7%( 18/19),92. 1%( 35/38),and 85. 7%( 18/21),97. 2( 35/36),92. 9%( 53/57).Comparison with pathological results(X^2 = 0. 000,P =1. 00) with no difference.Conclusion CESM examination has high diagnostic efficiency for suspicious calcification of breast.The images obtained by this method could have accurate and reliable clinical practical value in the determination of dense intra-mammary calcification lesions,the location of suspicious calcifications,and the evaluation of the nature of the lesions before surgery.
