ABSTRACT
Radioactive iodine scan is a quite specific method used for many years in differentiated thyroid cancer (DTC). However, combination of neck ultrasonography and serum thyroglobulin and anti-thyroglobulin has a high sensitivity in detection of disease. Furthermore, this method has gained an important role in routine clinical practice in follow-up of DTC, because it is a relatively cheap, practical and easily achievable method, with no radiation exposure. With the spread of the single photon emission computed tomography/computed tomography in the whole world, the place for radioiodine scan has been questioned again. Radioiodine scan has become a more frequently used method in clinical practice both in dosimetric applications, at early period after radioactive iodine therapy an long term follow-up with higher accuracy rates and proven prognostic importance.
