Description:

Brief Summary: The goal of this clinical trial is to test the imaging and diagnostic ability of [68Ga]-NOTA-SGC8 PET/MR in bladder cancer patients with different stages. The main questions it aims to answer are: Tumor specific lighting ability of [68Ga]-NOTA-SGC8 in bladder cancer patients with different stages. The safety of [68Ga]-NOTA-SGC8. Participants will be irrigated with [68Ga]-NOTA-SGC8 into the bladder for tumor imaging under PET/MR. The imaging performance of [68Ga]-NOTA-SGC8 on different stages of bladder tumors will be systematically evaluated by combining with pathological sections of patients. Urine accumulation and radioactivity distribution of [68Ga]-NOTA-SGC8 will be measured. The adverse events will be recorded.
