Radionuclide angiography for the diagnosis of thyroid cancer

The conventional static thyroid scan is sensitive but nonspecific in detecting thyroid tumors. Radionuclide angiography is a noninvasive and simple technique that can improve the specificity of the conventional scan significantly, since it can demonstrate hypervascularity of tumors. Our case reports demonstrated hypervascularity of the primary tumor and metastatic cervical lymph nodes.
