Abstract

Bladder tumors are the most common tumors in the urinary tract.Imaging plays a major role in the evaluation and staging of bladder cancer. Accurate tumor staging is essential for planning therapeutic strategies. Different imaging modalities are used including excretory urography, angiography, ultrasound and cross sectional imaging techniques.Cross sectional imaging modalities including CT and MRI are commonly used in detection and staging of bladder tumors.MRI offers several advantages such as multiplanar imaging with better detection of tumors, better tissue characterization, superiority in evaluation of prostatic or seminal vesicles invasion in addition to better differentiation between post biopsy effect and the tumor itself. Multiple MRI protocols were applied in this field however, recent inclusion of gadolinium enhanced dynamic MRI examination proved accuracy in tumor staging. With transrectal ultrasonography, higher frequency transducers can be used, allowing better spatial resolution for tumors in the body of the bladder, staging accuracies of 40% have been reported. The evaluation of perivesical tumor spread is limited, and US does not allow lymph node assessment. Ultrasound lacks the specificity to differentiate with confidence between neoplastic & inflammatory components of a mass.
