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.
