It will also allow a calculation of the volume of the gland. The imaging of the prostate is performed with a CAT scan and ultrasound. These images are then reconstructed utilizing software developed at Thomas Jefferson University and a three-dimensional model is created. The readiation oncologist and physicist use this model to determine the exact location of each seed. This treatment plan is used in the operating room and followed closely.
Additional seeds are available in order to make adjustments at the time of the implant.
To do this, a urinary catheter is inserted through the penis and into the bladder. A dye is injected through the urinary catheter to outline the bladder, making it easier to visualize on the CAT scan. The catheters are soft, flexible plastic and are removed at the end of the simulation. While the catheters are in place, you will have a CAT scan of your pelvic area. Your radiation oncologist and physicist will use the CAT scan and sophisticated computers to create a three-dimensional image of your pelvis and pelvic organs.
