Balloon brachytherapy for brain tumor-radiation safety experiences at the University of Medicine and Dentistry of New Jersey.

Balloon brachytherapy is a technique for the removal of a brain tumor in which an inflatable balloon is placed in a resection cavity and then filled with liquid I, delivering low energy dose to the cancerous cells surrounding the cavity. After preparing a patient room to mitigate any spills or contamination, liquid 125I (Iotrex) was assayed with a dose calibrator and injected into the balloon placed in the patient's brain.
