The study is an open label, non-randomized study designed to evaluate the diagnostic performance of SPECT CT. The study will consist of 3 cohorts, and a subset of the patients in cohort C will participate in a test-retest study, where the baseline SPECT/CT will be repeated.~SPECT CT will be performed in all cohorts.~Cohort A will evaluate SPECT CT by comparison to a Positron Emission Tomography (PET) scan using NaF.~Cohort B will evaluate SPECT CT by comparison to 18F-DCFPyL PET/CT.~Cohort C will evaluate SPECT CT by comparison to Whole Body Magnetic Resonance Imaging (WB-MRI).~Eligible subjects will be enrolled in a non-randomized manner per the treating physician discretion.
