A detailed representation is made of the technique used in the performance of thyroidography and an analysis is carried out of the authors' personal experience Thyroidography and thyroido-limphography have been applied in 40 patients with various diseases of the thyroid gland. The authors evaluate the method as being simple to perform, accessible, well tolerated and capable to provide significant morphological data (size of the lobes, the presence of retrosternal thyroid tissue, structure of the gland), also allowing for visualization of the cervical limph-nodes.

Looking for a standardization of the articular lymphoscintigraphy, an experimental research was conducted on 14 dogs injected in the ankle, with 2.5 mCi of 99m Tc-labeled dextran (P.M. = 70,000). Good scintigraphic images of the lymphatic system have been obtained. After having collected blood samples during the experimentation as well as aliquots of organs and of tissues, after the necropsy of the animal, it was verified that the 99m Tc-labeled dextran was useful for quantitative studies of the articular lymphatic drainage. The activities attained, in the drainage lymph nodes of injected articulation, are 152 times superior to those obtained in the kidney and one gramma of popliteal ganglion was 8929 times more active than one gramma of blood. The dextran 70,000, widely used in our clinical routine, can be injected to the human being, without any risk, and it may be the tracer which permits studies of the articular lymphatic drainage and the usage of the lymphoscintigraphy, already in expansion in many other Medicine branches, in the articular studies, nowadays.
Pelvic lymphoscintigraphy with 99 m Tc colloid injected directly in mesovarium during coelioscopy is able to schon that: drainage of ovaries' lymph is taken up by pelvic, paraortic or both lymph nodes, during genital activity ovarian lymph often diffuse in the other side of the pelvis with a true regional circulation.
