The gold standard for the diagnosis of thyroid cancer is the pathological diagnosis, and the pathological diagnosis usually requires surgery to achieve the purpose. What are the characteristics of the noninvasive medical imaging? This is a special problem for thyroid surgeons and patients, although there are some errors in clinical practice.

Here, we work experience through two aspects: thyroid and neck lymph nodes.

The characteristics of thyroid: nuclear medicine examination of thyroid carcinoma is cold nodules or cold nodules in ultrasound and CT generally have the following characteristics: microcalcification, unclear boundary, uneven texture, mass within and around the abundant blood supply can be cystic, cystic introrsus papillary protrusions. Along the long axis of the thyroid goiter is shorter than its vertical direction.

Lymph node metastasis: characteristics of neck lymph node calcification or cystic degeneration, corticomedullary unclear border lost normal lymph node target sign and characteristics of tail syndrome, loss of normal lymph hilum, lymph nodes or strengthen blood circulation around (that is around a ring-shaped reinforcement in strengthening CT), lymph node in the center can necrosis, lymph node by oval shape is round, consisting of a single variable for multiple aggregation or integration into the group, increased significantly, lymph nodes and surrounding soft tissue structure without normal boundary; nuclear medical examination found that the iodine absorption phenomenon can be diagnosed cervical lymph node, but no iodine absorption phenomenon can not be excluded.

Of course, if minimally invasive needle aspiration cytology of cervical lymph nodes found that there is no thyroid gland structure of the imaging data can be diagnosed, but sometimes not easy to do clinical.

The above is only work experience, hope to fellow criticism and appreciate!
