摘　　要：目的:对比探讨超声技术与磁共振成像(MRI)技术用于临床诊断乳腺BI-RADS3-5类肿物的效果与一致性。方法:选择2020年5月~2023年1月南京市高淳人民医院收诊治疗的乳腺肿物患者193例进行回顾性研究,均接受超声及MRI检查,以病理诊断结果为金标准,对比两种检查技术的灵敏度、特异性及准确率,分析诊断BI-RADS3-5类肿物的一致性。总结乳腺肿物患者的超声及MRI影像表现。结果:193例乳腺肿物患者经病理诊断结果显示,123例患者确诊为恶性乳腺肿瘤疾病,占比63.73%,70例患者诊断为良性乳腺肿瘤疾病,占比36.27%。超声技术诊断的灵敏度为91.06%、特异性为95.71%、准确率为92.75%;MRI技术诊断的灵敏度为93.50%、特异性为98.57%、准确率为95.34%;两项技术联合诊断的灵敏度、准确率均明显高于单一诊断(P<0.05)。超声与MRI诊断乳腺肿物定位的一致性较高。结论:临床诊断乳腺BI-RADS3-5类肿物通过超声技术与MRI技术均可获取良好的灵敏度与准确率,且肿物定位一致性较高,同时,二者联合诊断效果更为理想,能够为临床提供可靠影像及数据支持。Objective:To compare the effect and consistency of ultrasonography and magnetic resonance imaging in clinical diagnosis of BI-RADS3-5 breast tumors.Methods:A retrospective study was conducted on 193 patients with breast masses admitted and treated in Nanjing Gaochun People’s Hospital from May 2020 to January 2023.They were respectively examined by ultrasound and MRI.The sensitivity,specificity and accuracy of the two techniques were calculated using surgical pathological diagnosis results as the gold standard.The consistency of diagnosis of BI-RADS3-5 tumors was analyzed,and the consistency of localization of breast tumors diagnosed by ultrasound and MRI was also discussed.In addition,the ultrasonographic and MRI findings of patients with breast tumors were summarized.Results:Among 193 patients with breast tumors,123 cases were diagnosed as malignant breast tumors,accounting for 63.73%,and 70 cases were diagnosed as benign breast tumors,accounting for 36.27%.The sensitivity,specificity and accuracy of ultrasonic diagnosis were 91.06%,95.71%and 92.75%respectively.The sensitivity,specificity and accuracy of MRI were 93.50%,98.57%and 95.34%respectively.The sensitivity and accuracy of combined diagnosis of the two techniques were significantly higher than that of single diagnosis(P<0.05).In addition,the analysis results showed that ultrasound and MRI had a high consistency in the diagnosis of breast tumors.Conclusion:In clinical diagnosis of BI-RADS3-5 breast tumors,good sensitivity and accuracy can be obtained through both ultrasound and MRI technology,and the consistency of tumor location is better.Meanwhile,the combined diagnosis effect of the two is more ideal,which can provide reliable image and data support for clinical practice.
