Comparison of positron emission tomography with [(18)F]FDG and [(68)Ga]DOTATOC in recurrent differentiated thyroid cancer: preliminary data.

Abstract

[(68)Ga]DOTATOC and [(18)F]FDG PET showed comparable diagnostic performance in recurrent, radioiodine positive DTC. Due to much higher lesion detection rates, [(18)F]FDG PET should be preferred to [(68)Ga]DOTATOC PET in the work-up of radioiodine negative DTC relapse. These preliminary results have to be confirmed by more extensive data in further studies.
