Bladder contrast: influence on dose distribution In conformal radiotherapy can be avoided
Treatment planning systems: contouring of the contrasted bladder and asigning density value
•
Contrast enhanced CT simulator images
•
Delayed images or retrograde injection of contrast for improved
bladder delineation
•
Specific protocols required regarding contrast flow, image
aquisition delay
•
Safety precautions (allergic reactions, resuscitation equipment,
presence of physician during imaging).
Improvement of images through specific protocols
Computed Tomography
