Outcome Measures

Primary Outcomes (1)

  • Reliability under test retest conditions

    Regional brain uptake of \[18F\]FTC-146 will be analyzed by kinetic modeling with metabolite-corrected arterial input functions to establish stability and reproducibility of \[18F\] FTC-146 VT in humans (n=6) under test and retest conditions.

    1 week

Study Arms (1)

[18F]-FTC-146

EXPERIMENTAL

\[18F\]-FTC-146

Drug: [18F]-FTC-146

Interventions

Two 5 mCi \[18F\]-FTC-146 doses will be administered intravenously on two separate scan days at least one week apart (total per study = 10 mCi) Participants who complete both test days will receive 10 mCi total dose; however, if a participant is unable to return for a second test day due to unforeseen circumstances, they will receive 5 mCi total dose.

Also known as: Sigma-1 receptor radioligand
[18F]-FTC-146
