【摘要】 目的:探讨乳腺X线(mammography)与自动乳腺容积超声(automated breast ultrasound system,ABUS)检查对病变的检出效能。方法:收集2016年7月至2016年9月142例天津医科大学肿瘤医院经术后病理证实的乳腺良恶性病变患者的临床资料,共149个病变纳入研究,比较术前患者乳腺X线和ABUS检查对病变的检出率。结果:乳腺X线和ABUS检查对病变总检出率分别为87.2%(130/149)和98.0%(146/149),两者之间差异具有统计学意义(P<0.05)。乳腺X线和ABUS检查对乳腺癌的检出率分别为91.1%(92/101)和97.0%(98/101),两者之间差异无统计学意义(P>0.05);乳腺X线和ABUS检查对良性病变的检出率分别为79.2%(38/48)和100.0%(48/48),两者之间差异具有统计学意义(P<0.05)。ABUS在致密型乳腺中的病变总检出率及乳腺癌、良性病变检出率分别为97.7%(126/129)及96.5%(82/85)、100.0%(44/44),乳腺X线检查分别为86.0%(111/129)及90.6%(77/85)、77.3%(34/44),差异均具有统计学意义(P<0.05)。乳腺X线检查漏诊的为乳腺致密组织和腺体深面的病变,ABUS检查漏诊的多为钙化型病变。结论:ABUS检查对病变总检出效能及致密型乳腺中的病变检出效能均高于乳腺X线检查,漏诊的病变以钙化为主要影像学表现,乳腺X线检查对钙化型病变的检出具有独特优势。乳腺X线与ABUS检查在乳腺癌筛查中具有一定的互补作用。更多还原

【Abstract】 Objective: To compare the clinical utility of mammography with automated breast ultrasound system(ABUS) for detecting breast lesions. Methods: Data of 142 patients with 149 breast lesions who underwent both mammography and ABUS in Tianjin Medical University Cancer Institute and Hospital were collected from Jnly 2016 to September 2016. The detection rates of the two methods were then determined. Results: The overall detection rate using ABUS was significantly higher than that of mammography(mammography: 87.2% vs. ABUS: 98.0%, P<0.05). However, no significant difference was observed in breast cancer detection rates between mammography and ABUS(mammography: 91.1% vs. ABUS: 97.0%, P<0.05). Moreover, the benign lesion detection rate was significantly higher in ABUS than in mammography(mammography: 79.2%, vs. ABUS: 100%, P<0.05). In dense breasts, the detection rates of overall lesions, breast cancers, and benign lesions for ABUS were 97.7%, 96.5%, and 100.0%, respectively; whereas those for mammography were 86.0%, 90.6%, and 77.3%, respectively(P<0.05). Owing to overlapping dense breast tissue and deep anatomic location, several lesions were missed on mammography. Conversely, most lesions missed on ABUS presented as calcifications. Conclusion: Compared with mammography, ABUS can detect more lesions especially in dense breasts. However, ABUS failed to detect calcifications,whereas mammography had distinct advantages in this regard. Overall, the two methods had potential supplementary value for breast cancer screening.更多还原
