99mTc-QULIC-5-P1 SPECT Imaging in Patients With Prostate Cancer and Compared With 68Ga-PSMA-11 PET

99mTc-QULIC-5-P1 is a new radiotracer targeting PSMA, which is promising as an excellent imaging agent applicable to PSMA positive prostate cancer. This study will investigate the safety, biodistribution and potential usefulness of 99mTc-QULIC-5-P1 SPECT imaging for the diagnosis of lesions in PSMA positive prostate cancer.
