How difficult is it to diagnose oncologic pathology of the bladder on PET/CT? What dianostic techniques can help in this matter?

“I agree with you, evaluation of FDG metabolism of bladder lesions can be difficult mainly because the urinary excretion of FDG interferes with visualization of the primary bladder tumor. However, it’s important to keep in mind that the patient should void the bladder just before the PET acquisition. Besides that, placing a urinary catheter on the patient or delayed pelvic images after diuretic administration and oral hydration may help.”
