\[68Ga\]Ga-PSMA-D5 PET/CT was used for initial assessment of prostate cancer or detection of recurrence. The maximum standardized uptake value (SUVmax) was used to evaluate tumor uptake. The sensitivity, specificity, the number and accuracy of lesions identified and the distribution of lesions in each organ were calculated and compared with those of \[68Ga\]Ga-PSMA-11 PET/CT.
