Abstract:

【Abstract】Objective To investigate the efficiency of the combined approach of contrast-enhanced ultrasound and real-time elastography in the differential diagnosis of superficial lymphadenopathy. Methods Contrast-enhanced ultrasound and elastography were performed in 57 patients with biopsy proven superficial lymphadenopathy. Results The diagnosis accuracy of conventional ultrasound, contrast-enhanced ultrasound and elastography were 66.7%,68.4% and 77.2%,respectively. Conclusions Real-time elastography is beneficial for the diagnosis of superficial lympadenopathy, but the diagnostic efficacy of contrast-enhanced ultrasound is limited.

【摘要】 目的 探讨超声造影及弹性成像在浅表淋巴结鉴别诊断的临床应用价值。方法 对57例浅表淋巴结分别进行超声造影及弹性成像检查,以病理结果为金标准,评价这两种技术对于浅表淋巴结鉴别诊断的有效性。结果 57例浅表淋巴结,常规超声诊断准确率为66.7%,超声造影诊断准确率为68.4%,弹性成像诊断准确率为77.2%。结论 弹性成像有助于提高常规超声对浅表淋巴结的诊断效能。超声造影对于提高常规超声对浅表淋巴结的诊断效能作用有限。
