In a search for standardization of the technique of joint lymphoscintigraphy, an experimental study was carried out on  14 dogs in which the ankle joint was injected with 2.6 mCi of dextran 70.000 marked with 99mTc. With this method, good scintigraphic images of the lymphatic system were obtained. After having taken samples of blood during the examination and from the organs and tissues of the lymphatic tissues at necropsy of the animal, it was seen that 99mTc-labelled dextran 70.000 was suitable for quantitative studies of lymphatic drainage of joints. The activity found in the lymph nodes draining the injected joint was 152 times greater than that obtained from the kidney and one gram of popliteal lymph node concentrates 8,929 times as much activity as one gram of blood.
