18F-FDG PET, somatostatin receptor scintigraphy, and CT in metastatic medullary thyroid carcinoma: a clinical study and an analysis of the literature

Abstract

Overall, CT is similar or better than PET in our patients (dependent on the standard) while SRS is inferior to both other techniques. Our data are in agreement with publications that consider CT superior to PET in the diagnosis of metastatic MTC while other studies show superiority of PET. However, a combination of CT and PET seems to be the most appropriate non-invasive diagnostic approach in patients with MTC.
