Multicenter Study of 18F-Labeled NY104 for PET/CT Imaging in Renal Cell Carcinoma

Summary

Study on the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 18F-NY104 PET/CT in diagnosing primary, recurrent, and metastatic lesions of renal cell carcinoma; and investigate the effect of oral low-dose CAIX inhibitor (Acetazolamide) on the tissue distribution of 18F-NY104 in renal cell carcinoma patients, particularly in the stomach and kidneys.
