Computed tomography of the pelvis: sagittal and coronal image reconstruction in the evaluation of infiltrative bladder carcinoma.

The application of reconstructed images in the sagittal and coronal planes is discussed and illustrated with respect to the computed tomographic (CT) evaluation, including staging, of bladder carcinoma. Reconstruction CT was found to be particularly useful in delineating the craniocaudal extent of tumor. In addition, reconstructed images frequently aided the CT evaluation of the relationship of tumor mass to adjacent structures such as seminal vesicles and prostate gland. The improved anatomical orientation achieved by reconstruction was found useful in the presurgical evaluation of tumor site and extent of the lesion.
