The long half-life of 89Zr (T1/2 = 78.4 h) enables late time point imaging (up to 72 h in our study) with increased tracer uptake in tumor lesions and higher tumor-to-background ratios allowing identification of lesions non-visible on [68Ga]Ga-PSMA-11 PET/CT imaging. The gene discussed is FOLH1; the disease is neoplasm.
