Comparison of In-111 Octreotide and Tc-99m (V) DMSA Scintigraphy in the Detection of Medullary Thyroid Tumor Foci in Patients with Elevated Levels of Tumor Markers After Surgery

Abstract

These findings suggest that In-111 octreotide is superior to Tc-99m (V) DMSA and has a similar sensitivity rate to CT and MRI for the diagnosis of recurrent or metastatic MTC. Although the combined use of In-111 octreotide and Tc-99m (V) DMSA was most sensitive, the combined use of CT and MRI with radionuclide imaging methods may better detect more metastatic tumor foci.
