Imaging of the lymphatic system has always encountered difficulties, being costly, time-consuming, or producing low-resolution images. Each method of imaging provides its own challenges. The use of High-Resolution Ultrasound (HR-US) and Microvascular Flow Imaging (MFVI) may prove to be the most effective to visualize the superficial lymphatic vessels. We investigated the utilization of HR-US and MFVI in imaging inguinal lymph nodes and vessels and, the innovative use of an intranodal saline injection which acts as a contrast agent. This technical note aims to demonstrate that HR-US and MFVI, in combination with the intranodal saline injection, are applicable in the (dynamic) imaging of superficial inguinal lymph nodes and vessels.
