Automated analysis of investigational near-infrared fluorescence lymphatic imaging in humans

Near-Infrared Fluorescence Imaging in Humans with Indocyanine Green: A Review and Update.

Near-infrared (NIR) fluorescence imaging clinical studies have been reported in the literature with six different devices that employ various doses of indocyanine green (ICG) as a non-specific contrast agent. To date, clinical applications range from (i) angiography, intraoperative assessment of vessel patency, and tumor/metastasis delineation following intravenous administration of ICG, and (i...

Direct evidence of lymphatic function improvement after advanced pneumatic compression device treatment of lymphedema

Lymphedema affects up to 50% of all breast cancer survivors. Management with pneumatic compression devices (PCDs) is controversial, owing to the lack of methods to directly assess benefit. This pilot study employed an investigational, near-infrared (NIR) fluorescence imaging technique to evaluate lymphatic response to PCD therapy in normal control and breast cancer-related lymphedema (BCRL) sub...

Evaluation of Reflection Optical Imaging Characteristics Using Fluorescence with Near Infrared Wavelength at Different Depths of Tissue Equivalent Phantom

In vivo visualization and quantification of collecting lymphatic vessel contractility using near-infrared imaging

Techniques to image lymphatic vessel function in either animal models or in the clinic are limited. In particular, imaging methods that can provide robust outcome measures for collecting lymphatic vessel function are sorely needed. In this study, we aimed to develop a method to visualize and quantify collecting lymphatic vessel function in mice, and to establish an in vivo system for evaluation...

Mouse phenotyping with near-infrared fluorescence lymphatic imaging

We demonstrate the ability to non-invasively and quantitatively image lymphatic architecture and contractile function using dynamic near-infrared (NIR) fluorescence imaging with injection of indocyanine green in normal and transgenic mice. Unlike normal mice, which showed well defined lymphatic drainage patterns and orthograde propagation of contraction waves, we observed tortuous and mispatter...
