This study introduces a new imaging and analysis method for lymphatic function, improving diagnosis of lymphatic disorders. The approach enhances measurement reliability for lymphatic contractility, advancing lymphatic disease understanding and treatment.

Area of Science:

Biomedical Engineering
Physiology
Medical Imaging

Background:

Current lymphatic system imaging lacks standardized, non-invasive methods for real-time functional analysis.
Diagnosing lymphatic disorders is challenging due to insufficient spatial and temporal resolution in existing techniques.

Purpose of the Study:

To develop and validate a novel, reliable, and quantitative method for analyzing lymphatic contractility.
To improve the diagnosis and understanding of lymphatic disorders through enhanced imaging and analysis.

Main Methods:

Integration of near-infrared fluorescence lymphangiography with an advanced analytical workflow.
Combination of traditional peak-and-valley analysis with wavelet time-frequency analyses.
Application of variance component and generalizability studies to assess measurement reliability.
