Overview
Other diagnostic studies for papillary thyroid cancer include radioiodine scan, which demonstrates increased uptake of radioactive iodine at the areas of metastases and laryngoscopy which demonstrates vocal cord immobility.
Key Findings in (Name of Diagnostic Test) in (Disease Name)
- Thyroid total body scans are less reliable at finding recurrence than TG and ultrasound. Other options that have shown good results in identifying tumors or related outcomes are the use of thallium-201 chloride, which helps identify metastatic tumor; gallium scan, which is helpful to visualize lymphomas; I-metaiodobenzylguanidine (MIBG) which has proven useful in imaging MTC; Tc-MIBI, which has been effective in detecting deposits of metastatic thyroid cancer; PET scans, which are also helpful for the imaging of metastatic disease.Papillary thyroid cancer usually concentrates radioiodine, but not pertechnetate.
Nuclear Imaging
FDG-PET FDG-avid incidental FDG-avid thyroid nodules have ~40% risk of being a primary thyroid malignancy[1]
