Radiotherapy planning for simulation of prostate cancer: computerized tomographic scanning vs. conventional radiographic localization.
A computerized tomographic localization protocol for prostate cancer treatment planning is described. In 23 patients, this new method is compared to localization using conventional orthogonal radiographic simulation with contrast media in the rectum, bladder, and urethra. Advantages of the CT localization protocol include enhanced ability to delineate the tumor extension, particularly for superior, lateral, anterior, and posterior spread. Accurate CT localization of the inferior border of the target volume has also been demonstrated to be feasible, thereby avoiding the need for invasive urethral, bladder, and rectal manipulations.
