探讨高帧率超声造影在颈部浅表淋巴结诊断中的应用价值

摘要

目的 分析在对颈部浅表淋巴结诊断过程中按照高帧率超声造影进行诊断的作用。方法 按照对比观察的方式开展探究，选入2021年2月至2022年7月，本院收治的颈部浅表淋巴结患者66例为对象，均进行高帧率超声造影、常规超声造影，同时需本组患者进行病理学诊断。分析两种诊断方式和病理学诊断的差异。结果 在病理学诊断中，本组患者中恶性36例，良性30例，统计常规超声造影、高帧率超声造影检查结果，在准确度、敏感度、特异性、阴性预测值以及阳性预测值上，高帧率超声造影均高于常规超声造影，对比P<0.05。且在诊断淋巴结性质方面，高帧率超声造影同样具备优势，P<0.05。结论 在对颈部浅表淋巴结患者进行诊断的过程中选择高帧率超声造影进行诊断，可以有效保障对该部分患者诊断的准确性，有助于该部分患者尽快确诊。

Abstract

Objective To analyze the role of high frame rate contrast-enhanced ultrasound in the diagnosis of superficial cervical lymph nodes.
Methods According to the way of comparative observation, 66 patients with superficial cervical lymph nodes who were treated in our hospital from February 2021 to July 2022 were selected as the subjects, all of whom underwent high frame rate contrast-enhanced ultrasound and conventional contrast-enhanced ultrasound. At the same time, pathological diagnosis was required for the patients in this group. The differences between the two diagnostic methods and pathological diagnosis were analyzed.
Results In the pathological diagnosis, 36 patients were malignant and 30 patients were benign. The results of conventional contrast-enhanced ultrasound and high frame rate contrast-enhanced ultrasound were statistically analyzed. In terms of accuracy, sensitivity, specificity, negative predictive value and positive predictive value, high frame rate contrast-enhanced ultrasound was higher than conventional contrast-enhanced ultrasound (P<0.05). In terms of diagnosing the nature of lymph nodes, high frame rate contrast-enhanced ultrasound also has advantages (P<0.05).
Conclusion   High frame rate contrast-enhanced ultrasound can effectively guarantee the accuracy of diagnosis in patients with superficial cervical lymph nodes and help them to be diagnosed as soon as possible.
