Next-generation PET tracer enables rapid, high-precision detection of kidney cancer

MedicalXpress | يون 01, 2026

A new PET tracer targeting carbonic anhydrase IX (CAIX) has demonstrated exceptional sensitivity and high tumor-to-background contrast in detecting clear cell renal cell carcinoma (ccRCC), according to early clinical research. The newly developed tracer, 68Ga-RCC78, successfully identified additional metastatic lesions missed by standard imaging while significantly reducing abdominal background noise, offering a powerful new tool for kidney cancer staging.
