RadiosurgeryStereotactic radiosurgery or stereotactic radiotherapy delivers a precise radiation dose to a small tumor area. The term surgery may be confusing since no incision is actually made. How it worksThe use of stereotactic methods allows delivery of a high dose to the target (tumor) with significantly lower dose to brain tissue in the surrounding region. The result is an improved ability to control disease and a reduction in the risk of side effects from radiation therapy. What does it treat?At Legacy Emanuel Medical Center this unique form of radiotherapy can be delivered in a single session, termed stereotactic radiosurgery (SRS), or as a series of daily treatments , termed stereotactic radiotherapy (SRT). SRS and SRT are used for a variety of brain conditions. Tumors can be malignant (gliomas, metastases) or benign (acoustic neurinomas, pituitary adenomas, meningiomas). SRS is also used for certain nontumor conditions such as vascular malformations and trigeminal neuralgia. Over a decade of experienceLegacy Emanuel Medical Center was the first to bring this technology to the Portland Metropolitan area over a decade ago. In 2001 we made a large commitment in bringing the state of art Novalis Shaped Beam Radiosurgery site on line. This has allowed us to continue to improve our established brain program but also expand radiosurgery to areas outside the brain, including the spine. |
