We aimed to compare the diagnostic accuracy of mammography and ultrasonography and their breast imaging-reporting and data system (BI-RADS) classification versus breast core needle biopsy (CNB) findings in distinguishing the breast masses.
This cross-sectional study was conducted during 2016-2018 on female patients who were referred to a radiology center in Babol, northern Iran, for routine screening and/or for CNB. Patients underwent sonography and mammography by a senior radiologist. The breast lesions were also evaluated according to BI-RADS classification. CNB was performed on the breast masses by the same radiologist and pathological procedures were performed by an expert pathologist. Descriptive statistics were used to analyze the data.
In total, 213 breast masses were finally assessed, of which 107 (50.2 %) masses were benign and 106 (49.8 %) masses were malignant. The sensitivity for mammography and ultrasound alone was 72.6% and 68.9%, respectively. This rate for combined mammography and ultrasound was 84.9%. About BI-RADS classification, 28 masses were classified as BI-RADS 3, 99 as BI-RADS 4A, 4 as BI-RADS 4B, 18 as BI-RADS 4C, and 64 as BI-RADS 5. BI-RADS 4A had the highest sensitivity (70.1%) among BI-RADS categories. The highest specificity pertained to BI-RADS 3 and 5 (100%) among BI-RADS categories. Also, the highest accuracy was related to BI-RADS 5 (80.3%).
The results of the present study showed that combined mammography and ultrasound had a higher rate of accuracy than mammography or ultrasound alone. Furthermore, the imaging methods BI-RADS classification had an acceptable positive predictive value.
我们旨在比较乳腺钼靶摄影和超声检查及其乳腺影像报告和数据系统（BI-RADS）分类与乳腺粗针穿刺活检（CNB）结果在鉴别乳腺肿块方面的诊断准确性。
本横断面研究于2016年至2018年期间对转诊至伊朗北部巴博尔一家放射中心进行常规筛查和/或CNB的女性患者进行。患者由一名资深放射科医生进行超声检查和乳腺钼靶摄影。乳腺病变也根据BI-RADS分类进行评估。乳腺肿块由同一名放射科医生进行CNB，病理程序由一名专家病理学家进行。采用描述性统计分析数据。
总共最终评估了213个乳腺肿块，其中107个（50.2%）肿块为良性，106个（49.8%）肿块为恶性。单纯乳腺钼靶摄影和超声检查的敏感性分别为72.6%和68.9%。乳腺钼靶摄影和超声联合检查的这一比率为84.9%。关于BI-RADS分类，28个肿块被分类为BI-RADS 3，99个为BI-RADS 4A，4个为BI-RADS 4B，18个为BI-RADS 4C，64个为BI-RADS 5。在BI-RADS类别中，BI-RADS 4A的敏感性最高（70.1%）。在BI-RADS类别中，特异性最高的是BI-RADS 3和5（100%）。此外，准确性最高的与BI-RADS 5相关（80.3%）。
本研究结果表明，乳腺钼靶摄影和超声联合检查的准确率高于单纯乳腺钼靶摄影或超声检查。此外，成像方法BI-RADS分类具有可接受的阳性预测值。
