Brief 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.
Eligibility Criteria
Inclusion Criteria: * (1)Capable of understanding and voluntarily signing the informed consent form; able to complete the trial in accordance with the protocol requirements; (2)Age 18-75 years; no gender restrictions; (3)Clinically diagnosed/suspected as renal cell carcinoma or clinically diagnosed/suspected recurrence/metastasis after RCC treatment; (4)At least 1 measurable solid lesion in the subject, which can be accurately and continuously measured using modified RECIST criteria (version 1.1); (5)ECOG performance status score of 0-2; (6)Laboratory parameters must meet: 1.
