Study Summary

Patients with metastatic prostate cancer will undergo two protocol 68Ga-PET scans within 24-48 hours with 68Ga-PSMA-cyclotron and 68Ga-PSMA-generator radiotracers. The goal of the study is to evaluate repeatability and equivalence across the different 68Ga-PSMA production methods. This research study is being conducted to assess whether the PET/CT imaging results, as generated from the two different 68Ga production methods, are equivalent.

Primary Outcome

Single score Intraclass Correlation Coefficient (ICC) was calculated as an index for reliability between 68GA-PSMA-cyclotron versus 68Ga-PSMA-generator across varying pathologic lesions. The ICC, based on a one-way random effects model was used to assess reliability. The ICC ratios in this data shows the top five lesions with the greatest PSMA uptake (SUV) in each patient. This is a measure of the variance of interest (for the patient's lesion) over the total variance (from all data points for t
