【摘要】：目的探讨超微血管显像(SMI)技术对淋巴结良恶性鉴别诊断的临床应用价值。方法回顾分析62例浅表淋巴结肿大患者的超声检查资料,并与病理结果对照,比较二维灰阶超声联合CDFI、二维灰阶超声联合SMI及CEUS鉴别诊断良性淋巴结、淋巴瘤及恶性肿瘤淋巴转移的准确率。并以CEUS为金标准,分析淋巴结内微血管分布类型。结果62例患者共76枚浅表肿大淋巴结,其中良性淋巴结21枚,淋巴瘤32枚,恶性肿瘤淋巴结转移23枚。二维灰阶超声联合SMI与CEUS的诊断准确率均高于二维灰阶超声联合CDFI(χ~2=7.91、14.04,P=0.021、0.005),而二维灰阶超声联合SMI与CEUS间差异无统计学意义(χ~2=0.31,P0.05)。CDFI及SMI与CEUS对淋巴结内微血管分布类型的一致性均较高(Kappa=0.672、0.793)。结论 SMI与CEUS对判断淋巴结内微血管分布类型具有较高的一致性,有助于提高浅表肿大淋巴结定性诊断的准确率。
[Abstract]:Objective to evaluate the clinical value of simi technique in differential diagnosis of benign and malignant lymph nodes.Methods the ultrasonographic data of 62 patients with superficial lymphadenopathy were retrospectively analyzed and compared with pathological findings. The differential diagnosis of benign lymph nodes was compared between two-dimensional gray scale ultrasound and CDFI, two-dimensional gray scale ultrasound combined with SMI and CEUS.Accuracy of lymphatic metastasis of lymphoma and malignant tumor.Using CEUS as the gold standard, the distribution of microvessels in lymph nodes was analyzed.Results there were 76 superficial enlarged lymph nodes in 62 patients, including 21 benign lymph nodes, 32 lymphomas and 23 malignant lymph nodes metastasis.The diagnostic accuracy of two-dimensional gray scale ultrasound combined with SMI and CEUS was higher than that of two-dimensional gray scale ultrasound combined with CDFII (蠂 ~ 2 / 27.91 ~ 14.04 ~ 14.04 ~ 0.021 ~ 0.005), but there was no significant difference between two-dimensional gray scale ultrasound combined with SMI and CEUS (蠂 ~ (2) 0.31) P 0.05. CDFI and SMI and CEUS were more consistent in the distribution of microvessel in lymph nodes.Conclusion SMI and CEUS are consistent in judging the distribution of microvessels in lymph nodes, which is helpful to improve the accuracy of qualitative diagnosis of superficial enlarged lymph nodes.
