【摘要】 目的分析颈部淋巴结超声造影的增强特点和动态血管模式曲线(DVPC)的类型,探讨其在颈部淋巴结疾病诊断中的价值。方法选取95例颈部淋巴结增大患者,根据病理结果分为反应性淋巴结组34例、转移性淋巴结组43例和淋巴瘤组18例,均行超声造影检查。应用SonoLiver软件进行后处理以获取DVPC,比较各组超声造影表现和DVPC的类型及特征。结果反应性淋巴结组中82.4%表现为离心性增强,85.3%呈均匀性增强,97.1%不伴无增强区;转移性淋巴结组中69.8%表现为向心性增强,74.4%呈不均匀增强,65.1%伴无增强区;淋巴瘤组中44.4%表现为离心性增强,38.9%表现为混合性增强,55.6%表现为均匀性增强,83.3%不伴无增强区,各组淋巴结超声造影增强特点比较,差异均有统计学意义(均P<0.05)。反应性淋巴结组41.2%DVPC表现为正负双向波;转移性淋巴结组44.2%DVPC表现为负向波;淋巴瘤组44.4%DVPC表现为正负双向波,三组间颈部淋巴结DVPC类型比较差异有统计学意义(P<0.05),转移性淋巴结组淋巴结DVPC类型与反应性淋巴结组、淋巴瘤组比较,差异均有统计学意义(均P<0.05)。结论颈部增大淋巴结超声造影增强特点和DVPC类型对淋巴结鉴别诊断具有较好的临床价值。更多还原

【Abstract】 Objective To analysis the perfusion characteristics of contrast-enhanced ultrasonography(CEUS)and the types of dynamic vascular pattern curve(DVPC)of cervical lymph nodes,and to explore the value of CEUS and DVPC in diagnosis of cervical lymphadenopathy.Methods According to the pathological results of 95 cases with enlarged cervical lymph node,34 cases with reactive lymph nodes,43 cases with metastatic lymph nodes and 18 cases with lymphoma were enrolled.CEUS was performed,and SonoLiver software was used for post-processing to acquire DVPC. CEUS manifestations and types and characteristics of DVPC were compared anong the three groups.Results In the reactive lymph node group,82.4% showed eccentricity enhancement,85.3% showed uniformity enhancement,97.1% showed no enhancement zone.In metastatic lymph node group,69.8% showed centripetal enhancement,74.4% showed uneven enhancement,65.1% showed no enhancement zone.In lymphoma group,44.4% showed eccentricity enhancement,38.9% showed mixed enhancement,55.6% showed uniformity enhancement,83.3% showed no enhancement zone.All of the above contrast enhancement characteristics of lymph nodes in each group were compared,the differences were statistically significant(all P<0.05).41.2% DVPC in the reactive lymph node group showed positive and negative wave,44.2% DVPC in metastatic lymph node showed negative wave,44.4% DVPC in lymphoma showed positive and negative wave,and the difference of DVPC in cervical lymph nodes among three groups was statistically significant(P<0.05),the DVPC of lymph node in metastatic lymph node group was significantly different compared with that of reactive lymph node group and lymphoma group(all P<0.05).Conclusion Perfusion characteristics of CEUS and the types of DVPC could provide more information for differential diagnosis of enlarged cervical lymph nodes.更多还原
