Objective To compare the diagnosis value of full-field digital mammography (FFDM) and ultrasound light scattering imaging (OPTIMUS) on breast, tumor. Methods 60 patients suspected with breast cancer in our hospital were selected and they were all given FFDM and OPTIMUS detection in order to compare the diagnosis accuracy of the two imaging methods with pathological diagnosis as the "gold standard'1. Results 62 tumor were detected in all patients, postoperative pathologic diagnosis showed 40 benign tumore and 22 malignant tumors. The diagnostic accuracy of Ultrasonic light scattering imaging was 79.0%, sensitivity was 77.3%, specificity was 80.0%; the diagnostic accuracy of all-digital mammography was 74.2%, sensitivity was 81.8%. and specificity was 70.0%.. Diagnostic indicators of the two methods compared, the difference was not statistically significant (P ＞ 0.05). Conclusion The diagnostic accuracy of ultrasonic light scattering imaging and full field digital mammography in breast tumors are basically the same, and the former has no radiation injury, and it has a greater advantage in the mass positioning, qualitative diagnosis, so it can be used as an effective complement to diagnostic imaging of breast tumors.%目的 比较全数字化乳腺摄影与超声光散射成像对乳腺肿瘤的诊断价值.方法 选取我院收治的疑似乳腺肿瘤患者60例,均进行全数字化乳腺摄影检查及超声光散射成像,以病理诊断为"金标准",比较两种影像检查方法对乳腺肿瘤诊断的准确性.结果 全部患者共检出62个肿块,术后病理确诊为良性肿块40个,恶性肿块22个.超声光散射成像诊断准确率为79.0%,敏感度为77-3%,特异度为80.0%;术前全数字化乳腺摄影诊断的诊断准确率为74.2%,敏感度为81.8%,特异度为70.0%.两种方法各诊断指标比较,差异无统计学意义(P>0.05).结论 超声光散射成像与全数字化乳腺摄影诊断乳腺肿瘤的诊断准确性基本相同,并且前者无放射损伤,在肿块定位、定性诊断中有较大优势,可以作为乳腺肿瘤影像诊断的有效补充.
