Fig. 2From: Computed tomography urography with corticomedullary phase can exclude urinary bladder cancer with high accuracyUrinary bladder cancer attenuation in a coronal computed tomography urography reconstruction in: a unenhanced phase, b corticomedullary phase (CMP), c nephrographic phase, and d excretory phase. Notice that the tumor is clearly seen in CMP due to good enhancement and it is hidden in the not optimal contrast-mixed urine in the bladder in (d), sometimes happening despite efforts to get high concentration and volume of contrast in the bladderBack to article page
