Uterine cervical cancer with urinary bladder invasion is classified as stage IVA with poor prognosis. Cystoscopy is a diagnostic procedure but relatively invasive examination. MRI can rule out the bladder invasion and skipping cystoscopy may be possible, however, high false positive rate may be problematic. The bladder mucosal invasion in 14 cases was evaluated with reduced FOV DWI (rFOV-DWI) and compared with cystoscopic findings. The diagnosis of invasion had a sensitivity of 100%, specificity of 50%, accuracy of 93%, PPV of 92%, and NPV of 100%. Addition of rFOV-DWI may improve the staging accuracy in assessing the bladder mucosal invasion.
