High FDG and low FLT uptake in a thyroid papillary carcinoma incidentally discovered by FDG PET/CT

Clin Nucl Med. 2012 Jun;37(6):607-8. doi: 10.1097/RLU.0b013e318252d80f.

Abstract

We report a 58-year-old man whose incidentally discovered papillary thyroid carcinoma in the left lobe showed high FDG and low FLT uptake on PET/CT. The SUVmax was 19.7 for FDG and 3.0 for FLT. The Ki-67 labeling index of the tumor was 1.9%. Thus, the low FLT uptake might be attributed to the low proliferative activity of this cancer.
