Dynamic lymphadenoscintigraphy of the lower limbs (notes on technique and normal findings)

The use of dynamic lymphadenoscintigraphy is proposed for the study of the lymphatic flow in the lower limbs. The method is based on the determination of the flow curves of radiocolloid (antimony-sulphide labelled with 99mTc) in the lower limbs, on the time of its appearance in the inguinal lymphatic vessels and in the liver, and also on the recording by periodically repeated photoscans of the progress of the radiocolloid in the pre-lymph node ducts. Thus, the method is suggested for use in the observation of flow variations as an expression of metastatic or systemic lymph node diseases and in the differential diagnosis of lymphatic and venous oedema.
