Brief Summary:
This study is a single centre non-randomized non-blinded phase II prospective cohort study including 50 participants. The objective of this study is to directly compare 68Ga-HA-DOTATATE, 18F-DOPA, and 18F-FDG activity in patients with metastatic neuroendocrine tumors (NETs) on a lesion-by-lesion basis. The investigators will determine the prevalence of concordant versus discordant disease. Secondary objectives include assessing the standardized uptake value (SUV) and determining if there is any correlation between discordance and disease progression.

Drug Information available for: Furosemide

Arm Intervention/treatment
Experimental: 18F-DOPA PET/CT scan
4 MBq/kg (minimum 100 MBq, maximum 600 MBq) 18F-DOPA injected intravenously with 40 mg furosemide and subsequent whole body PET/CT scan
Diagnostic Test: 18F-DOPA with furosemide
Diagnostic 18F-DOPA PET/CT scan




Primary Outcome Measures :
  1. Lesion-to-lesion comparison of activity on 68Ga-HA-DOTATATE, 18F-DOPA, and 18F-FDG PET/CT scans [ Time Frame: Within 1 year after completion of both 18F-DOPA and 18F-FDG PET/CT scans ]
    Participants will be categorized as having concordant disease (all lesions 68Ga-HA-DOTATATE avid) or discordant disease (one or more lesions not 68Ga-HA-DOTATATE avid).


Secondary Outcome Measures :
  1. SUV of lesions on 68Ga-HA-DOTATATE, 18F-DOPA, and 18F-FDG PET/CT scans [ Time Frame: Within 1 year after completion of both 18F-DOPA and 18F-FDG PET/CT scans ]
    SUVmax of all lesions on all scans will be recorded and compared to SUVmean of the liver and blood pool

  2. Assessment of disease progression - 12 months [ Time Frame: 12 months after completion of the 68Ga-HA-DOTATATE, 18F-FDG, and investigational 18F-DOPA PET/CT scans ]
    All available clinical information will be reviewed 12 months after completion of the PET/CT scans with expert determination of treatment response, no treatment response, or disease progression

  3. Assessment of disease progression - 18 months [ Time Frame: 18 months after completion of the 68Ga-HA-DOTATATE, 18F-FDG, and investigational 18F-DOPA PET/CT scans ]
    All available clinical information will be reviewed at 18 months after completion of the PET/CT scans with expert determination of treatment response, no treatment response, or disease progression
