【摘要】：目的探讨超声"萤火虫"成像技术对乳腺肿块微钙化的检出能力及其在乳腺肿瘤诊断中的价值。方法乳腺肿块患者153例(172个病灶)。行钼靶X线、常规超声及超声"萤火虫"成像技术检查,观察肿块微钙化情况。以钼靶X线检查结果为参照,评价超声"萤火虫"成像技术对微钙化的检出情况;以病理检查结果为参照,评价超声诊断乳腺恶性肿瘤的准确度。结果 (1)超声"萤火虫"成像技术检出乳腺肿块内微钙化的特异度97.8%、灵敏度98.8%和准确度98.3%均明显高于常规超声的83.5%、49.4%和67.4%,差异具有统计学意义(P0.05);(2)不同形态的微钙化灶,超声"萤火虫"成像均表现为点状强回声;钼靶X线检查成簇状分布和区域样分布的微钙化,超声"萤火虫"成像表现为簇状分布,散在分布的微钙化也表现为散在分布;(3)ROC分析结果显示:超声"萤火虫"成像技术诊断乳腺恶性肿瘤的准确度明显高于常规超声,差异具有统计学意义(P0.05)。结论超声"萤火虫"成像技术可提高乳腺肿块微钙化的检出率,显示微钙化分布特征,从而提高超声诊断乳腺恶性肿瘤的准确度。
[Abstract]:Objective to investigate the detection of microcalcification in breast masses by ultrasound firefly imaging and its value in the diagnosis of breast tumors. Methods 153 patients (172 lesions) with breast mass were included. Mammography, conventional ultrasound and firefly imaging were performed to observe the microcalcification of the tumor. The detection of microcalcification by ultrasonic "firefly" imaging technique and the accuracy of ultrasonic diagnosis of breast malignant tumor were evaluated by using the results of mammography as the reference. Results (1) the specificity of ultrasound "firefly" imaging in detecting microcalcification in breast masses was 97.8. the sensitivity and accuracy were 98.8% and 98.3%, respectively, which were significantly higher than those of conventional ultrasound (83.5% and 67.4%). The difference was statistically significant (P0.05). (2) the ultrasound "firefly" imaging of the microcalcified foci with different morphology showed the dot strong echo; The microcalcification of cluster distribution and regional distribution was detected by molybdenum target X-ray. The ultrasonic "firefly" imaging showed cluster distribution, and the scattered microcalcification was also distributed. (3) the results of ROC analysis showed that the accuracy of ultrasound "firefly" imaging in the diagnosis of breast malignant tumors was significantly higher than that of conventional ultrasound, and the difference was statistically significant (P0.05). Conclusion Ultrasound "firefly" imaging technique can improve the detection rate of microcalcification in breast masses and display the distribution of microcalcification, thus improving the accuracy of ultrasound in the diagnosis of breast malignant tumors.
