Iodine-131 ((131)I) total-body scintigraphy is a commonly used post-thyroidectomy imaging procedure in the management of differentiated thyroid cancer (DTC), in particular in patients with an intermediate or high risk of persistent or recurrent disease, in combination with serum thyroglobulin (Tg) determinations and ultrasonography of the neck. It can show the persistence of residual thyroid tissue after thyroidectomy and local and distant metastases. Although this is a highly sensitive method for detecting normal and pathologic thyroid tissue, especially when performed after an ablative dose of (131)I, false-positive scans (i.e., uptake in the absence of residual thyroid tissue or metastases) can occur in different situations.

Abstract

Iodine-131 ((131)I) total-body scintigraphy is a commonly used post-thyroidectomy imaging procedure in the management of differentiated thyroid cancer (DTC), in particular in patients with an intermediate or high risk of persistent or recurrent disease, in combination with serum thyroglobulin (Tg) determinations and ultrasonography of the neck. It can show the persistence of residual thyroid tissue after thyroidectomy and local and distant metastases. Although this is a highly sensitive method for detecting normal and pathologic thyroid tissue, especially when performed after an ablative dose of (131)I, false-positive scans (i.e., uptake in the absence of residual thyroid tissue or metastases) can occur in different situations.
