CT cystography and virtual cystoscopy in the assessment of new and recurrent bladder neoplasms

Conclusion: CT cystography is very accurate at identifying masses larger than 0.5 cm and can show mucosal abnormalities as small as 2 mm. It is minimally invasive and can be diagnostic when conventional cystoscopy is inconclusive. It can indicate appropriate areas for assessment and biopsy at conventional examination. Virtual cystoscopy gave comparable views to conventional cystoscopy, but did not add diagnostic information. It is not likely to replace conventional cystoscopy, but may be helpful in occasional circumstances where the latter is inconclusive, or can not be performed.
