Early acquisition of [¹⁸F]FDOPA PET/CT imaging in patients with recurrent or residual medullary thyroid cancer is safe-and slightly better!

ABSTRACT:

Purpose

The aim of this study was to compare early (15 min) and late (60 min) [¹⁸F]FDOPA PET/CT acquisition times in the detection of recurrence/residual disease in medullary thyroid cancer (MTC) patients.

Materials and methods

Thirty-two dual-phase [¹⁸F]FDOPA PET scans were retrospectively reviewed. Scan indications were (1) suspected recurrence of MTC, (2) treatment monitoring, or (3) restaging. In four scans, no final verification could be obtained, and one scan was excluded due to non-consistency with the acquisition protocol. Images were analyzed visually and semiquantitatively (using SUV_max). On both per-scan and per-lesion basis, early (median time 15 min) and late (median time 60 min) acquisition were compared by number and SUV_ma
