Improved dose distribution with customized I-125 source loading in temporary interstitial implants.
I-125 sources are being used in temporary interstitial implants of various sites. Radiation safety considerations favor its use over other available radioisotopes. Cost containment is achieved by using the same sources for a number of patients. Loading I-125 seeds into implant catheters at our institutions permit customized source arrangement to optimize the implant dose patterns. Clinical examples are given for which the dose distributions achieved with customized source loading are superior to those achievable with standard Ir-192 ribbons.
