Department of Radiotherapy ❯ Our Techniques ❯ Remote High Dose Rate (HDR) Afterloading Brachytherapy

Flexitron Afterloading Brachytherapy delivery system utilizes tiny radioactive source (Iridium-192) to deliver radiation dosage at a short distance by interstitial, intracavitary, or intraluminal application. Having this mode of therapy, a high radiation dose can be delivered locally to the tumor with rapid dose fall-off, thus minimizing dose to the surrounding normal tissues.

Suitable cases for Brachytherapy include:

• Cancers of the uterine cervix, uterine body and vagina
• Interstitial boost in breast cancer treatment
• Boost in nasopharyngeal carcinoma treatment after external beam radiotherapy
• Recurrence and re-treatment of neck disease
• Intraluminal boost in esophageal cancer treatment, etc.

Image-Guided Brachytherapy (IGBT)
Image-Guided Brachytherapy (IGBT) is the use of advanced imaging techniques such as Magnetic Resonance Imaging (MRI) in brachytherapy treatment. MR images are acquired after applicator insertion to provide accurate positional information.

The benefits of MRI-guided brachytherapy include:

• Superior soft tissue definition in three-dimensions (3D) for target and organ-at-risk (OARs) delineations
• Highly accurate needle and applicator placements
• Better treatment outcome
• Fewer radiation-induced side effects
