Diagnostic performance of 68Ga-DOTATOC PET-CT, 18F- FDG PET-CT and 18F-DOPA PET-CT. Abbreviations: NP = not performed; PET = positron emission tomography; CT = computed tomography; DOTATOC = 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid tyr3- Octreotide; FDG = fluoro-2-deoxy-D-glucose; DOPA = 3,4-dihydroxyphenylalanine; SUV = standardized uptake value. * = the lesion(s) appeared later during the follow-up and no 68Ga-DOTATOC PET-CT was performed.
