The Uptake of Radioactive Iodine Before and After a Low Iodine Diet in Patients With Differentiated Thyroid Carcinoma
The goal of this clinical trial is to compare the difference in thyroid uptake of a low dose radioactive iodine (10 MBq 123-I or 37 MBq 123-I) in athyreotic patients with differentiated thyroid carcinoma before and after a low iodine diet (LID) of 7 days. The main question it aims to answer is: • What is the difference in iodine uptake before and after a LID of 7 days? Uptake of a low dose of 123-iodine will be measured in participants before and after a low iodine diet of 7 days. Researchers will compare the uptake (%) before and after the LID.
• Patients, men and women above the age of 18 years, have to be diagnosed with DTC and have to follow a LID prior to the 131I ablation therapy according to the Dutch DTC guideline
• Patients have to be fit to adhere to the study protocol
• Patients have to be able to read and understand the Dutch language
