Indocyanine Green: our best option for lymphatic visualisation and our path to improved outcomes for patients?

Lymphoscintigraphy has been the benchmark for structural and functional lymphatic assessment of the deep lymphatic system (Narushima et al, 2016). We can derive quantitative and qualitative observations of the deep lymphatic system from it at specific regions of interest. However, its negatives are the relative ‘obscurity’ or lack of clarity of the images; it’s an invasive process and the patient is exposed to radiation.
