The lymphatic system is an integral part of the microcirculatory bed, which structurally and functionally complements the venous bed. It ensures constancy in the internal environment of the human body and performs transport, barrier, lymphopoietic, and immune functions, playing an exceptional role in the metabolism and cleansing of the body’s cells and tissues from metabolic products. The researchers assume that the meningeal lymphatic vessels (MLVs) may be involved in the process of cleansing the brain from metabolic products. Today, the problem of proving the existence of MLVs is a key one in understanding the anatomy and physiology of processes in the brain as a whole. Medical imaging techniques make it possible to prove the presence of MLVs. The paper analyzes the methods that are currently more frequently used to determine MLVs. Experimental medical imaging techniques allow us to conduct researches, by confirming or ruling out the scientific theories put forward. These methods are further evidence-based medicine.
