68Ga-C1 PET/ CT Imaging in Clear Cell Renal Cell Carcinoma

Summary

The goal of this clinical trial is to evaluate the diagnostic value of CAIX protein specific probe 68Ga-C1 in PET/CT imaging in clear cell renal cell carcinoma patients. It will also learn about the safety, tolerability and radiation dosimetry of 68Ga-C1. Researchers will compare the diagnostic value of 68Ga-C1 PET/CT and 18F-FDG PET/CT in Chinese patients with indeterminate renal masses or confirmed clear cell renal cell carcinoma.
