Radiation therapy can shrink or kill tumor cells. We use three types of radiation for acoustic neuroma. We base the decision of which to recommend for you on such considerations as the type, size, and location of the acoustic neuroma tumor.
The latest radiation therapy techniques we use to treat acoustic neuroma include:
With frame-based radiosurgery, we place a frame (called a stereotactic frame) over your head. This frame allows the operator to pinpoint where the radiation beam will go so it reaches the acoustic neuroma. This method is a highly precise, minimally invasive way of delivering radiation directly to a tumor with little or no impact on surrounding structures. This procedure is usually given as a one-time treatment on an outpatient basis.
Intensity-modulated radiation therapy (IMRT)
Intensity-modulated radiation therapy (IMRT) uses sophisticated software and 3-D images from CT scans to focus high doses of radiation directly onto your tumor. These pencil-thin beams vary in intensity and conform to the specific shape and size of the tumor. This highly focused approach reduces the exposure of healthy tissue in your brain. IMRT can decrease your chance of radiation side effects.
Image-guided radiation therapy (IGRT)
This approach uses real-time imaging with CT scans or x-rays during radiation therapy to help ensure ideal positioning and lack of motion during treatment. IGRT enables your treatment team to deliver radiation with great accuracy.
