Analysis of soft tissue hardness changes in cervical lymph node enlargement based on multimodal ultrasound parameters...

Lipoprotein metabolic regulation plays a vital role in human health and disease, with its abnormalities closely associated with the onset and progression of various disorders. In cases of lymphadenopathy, this study aimed to develop a linear model based on multimodal ultrasound parameters and lipoprotein metabolic regulation, predicting changes in intraluminal and perilymphatic tissue stiffness during cervical lymphadenopathy to provide clinical guidance for assessing lymph node characteristics. All patients underwent multimodal ultrasound examinations including conventional 2D ultrasound, colour Doppler ultrasound, and elastography. The linear model developed based on these factors demonstrated high predictive power, indicating that changes in lipoprotein metabolism are closely linked to the pathophysiological processes of lymph nodes. In lymphadenopathy, lipoprotein metabolic regulation affects local inflammatory responses and extracellular matrix remodelling, thereby influencing lymph node stiffness and function. Additionally, lipoprotein regulation indirectly impacts lymph node hardness by modulating angiogenesis and extracellular matrix remodelling.
