Both computed tomography and magnetic resonance imaging show a distinctive honey-comb pattern within the lymphatic system that helps differentiate lymphedema from other potential cancer-related causes of edema such as deep vein thrombosis [19]. Lymphangiography was used extensively in the past as an imaging technique, but it is associated with inflammation, scarring, and atrophy of the lymph vessels that can further impair lymph transport capacity. [19]. Lymphoscintigraphy, the method of injection of a radioactive tracer into the subdermal region of the affected limb and monitoring with a gamma camera, has been used in a preliminary way to predict those at increased risk for lymphedema after axillary treatment [19]. The specific advantage of lymphoscintigraphy is that it can identify pathways of lymphatic drainage, dermal backflow, collateral lymph channels, number of lymph nodes, and clearance times of the radiophamaceutical
