Analysis of the radiographic x-ray through thyroid lymph by hypodermic injection

The normal net-veined lymphatic vessel structure of thyroid gland is around the thyroid lobule. It is a passage of the excretion of the thyroid secretion. It is also the passage of the proliferation and metastasis of a carcinoma. By using myodil radiographic technology and injecting through the middle part of the neck, the structure of the thyroid gland can be demonstrated. This method has turned out to be valuable to know different kinds of diseases in the thyroid gland, to tell whether there are pathological changes and to diagnose malignant thyroid cancer, benign thyroid tumour and thyreoitis.
