Comparison of virtual cystoscopy and transabdominal ultrasonography with conventional cystoscopy for bladder tumor detection.

Purpose: We compare virtual cystoscopy (VC) and transabdominal ultrasonography (US) with conventional cystoscopy (CC),the gold standard, for detection of bladder tumors.

Patients And Methods: Forty-five patients suspected to have bladder neoplasms were evaluated prospectively.They underwent transabdominal US, followed by VC and CC.

18F-FDG PET/CT delayed images after diuretic for restaging invasive bladder cancer.

Unlabelled: PET with (18)F-FDG has been considered of limited value for detection of bladder cancer because of the urinary excretion of the tracer. The purpose of this study was to investigate the role of PET/CT in the detection and restaging of bladder cancer using furosemide and oral hydration to remove the excreted (18)F-FDG from the bladder.

Methods: Seventeen patients with bladder cancer (11 without cystectomy, 6 with total cystectomy and urinary diversion) underwent (18)F-FDG PET/CT from head to the upper thighs 60 min after the intravenous injection of 370 MBq of (18)F-FDG.
