Exploring the Clinical Application Value of CAIX-Targeted PET Imaging in Renal Cancer Patients

This study explores the use of a specialized PET imaging scan that targets a protein called CAIX (carbonic anhydrase IX), which is found in high amounts in kidney cancer cells. Researchers want to see if this new scan can more accurately detect and stage kidney cancer compared to standard imaging. **You may be eligible if...** - You are between 18 and 75 years old - You have clinically suspected or confirmed kidney cancer (including clear cell, papillary, or chromophobe subtypes) - You have had an enhanced CT scan within the past 2 weeks - Your organ function and blood counts are within acceptable ranges (ECOG 0–3) **You may NOT be eligible if...** - You are pregnant or breastfeeding - You have an acute systemic illness or condition that could interfere with imaging interpretation - You or your legal representative are unable or unwilling to sign the consent form Talk to your doctor to see if this trial is right for you.
