CT detection of small and flat bladder lesions multiplanar reformation (MPR) in three patients of urothelial carcinoma. Axial (a) and sagittal (b) urothelial phase CT images of a 73-year-old woman showing an enhanced area of focal wall bladder thickening (arrows). Axial (c) and sagittal (d) urothelial phase CT images of a 58-year-old woman showing two tiny enhancing lesions (arrows) on the anterior wall of the bladder. Axial urothelial (e) and excretory (f) phase CT images of a 71-year-old woman showing subtle diffuse or segmental mucosal enhancement of the bladder without filling defects. The patient was diagnosed with urothelial carcinoma in situ on histopathological examination. Small or flat lesions are more difficult to detect with CT
