Methods: All accessible MRI examinations from 128 women during a limited time period in 2016 were evaluated. A blinded radiologist visually categorized BPE as minimal, mild, moderate, or marked. A BI-RADS category was also assigned. We used descriptive statistics to report the findings and chi-square and Fisher’s exact tests to compare categories. Results: Prevalence of minimal, mild, moderate, and marked BPE was 14.1%, 43.0%, 32.0%, and 10.9%, respectively. The short-interval follow-up rates were 22.2%, 27.3%, 26.8%, and 7.1% in women with minimal, mild, moderate, and marked BPE, respectively. BPE was not associated with the short-interval follow-up rate (p-value = 0.477). Biopsy rates were 22.2%, 27.3%, 22.0%, and 57.1% in women with minimal, mild, moderate, and marked BPE, respectively. Although there was no significant relationship between biopsy rates and BPE levels (p-value = 0.095) in the total population, these two factors were significantly associated in premenopausal women (p-value = 0.023) and in women of 30 - 39 years (p-value = 0.001). Conclusion: Higher BPE does not correlate with short-interval follow-up rates, but appears to be related to biopsy rate, thus causing false-positives and unnecessary biopsy recommendations, particularly in younger, premenopausal women.展开更多
目的分析乳腺影像报告及数据系统(breast imaging reporting and data system,BI-RADS)4类乳腺良恶性结节采用超声弹性成像(ultrasonic elastography,UE)技术诊断的价值。方法选择2023年1—11月济南市章丘区人民医院收治的102例疑似BI-R...目的分析乳腺影像报告及数据系统(breast imaging reporting and data system,BI-RADS)4类乳腺良恶性结节采用超声弹性成像(ultrasonic elastography,UE)技术诊断的价值。方法选择2023年1—11月济南市章丘区人民医院收治的102例疑似BI-RADS 4类乳腺实性结节患者为研究对象,全部患者均接受彩色多普勒超声与UE检查。以病理结果为“金标准”,针对BI-RADS 4类乳腺良恶性结节经常规超声与UE技术诊断的结果及效能,以及对UE技术诊断结果与病理结果的一致性进行评价。结果BI-RADS 4类乳腺良恶性结节经穿刺活检结果证实为恶性36例,良性66例,UE技术诊断结果与病理诊断结果具有极好的一致性(kappa=0.890)。UE技术对BI-RADS 4类乳腺良恶性结节诊断的灵敏度94.44%、特异度95.45%、准确度95.10%均高于常规超声的72.22%、81.82%、78.43%,差异有统计学意义(χ^(2)=6.400、6.092、12.337,P均<0.05)。结论UE在BI-RADS 4类乳腺良恶性结节中具有较为理想的诊断价值,进一步提高了诊断效能,为临床提供可靠的参考信息。展开更多
