Stereotactic Radiosurgery

Stereotactic radiosurgery is a procedure which utilizes very accurate targeted radiation in large doses to effectively kill a tumor or destroy a lesion. It is considered a non-invasive procedure that has been used as an effective alternative to surgery or conventional standard fractionated radiation therapy for treating small tumors and other select medical conditions as the fraction of radiation utilized here is less than the conventional.

It utilizes image guided localization of a target with many radiation beams that can limit the dose to adjacent normal structures there by giving maximum accuracy to specific target reducing radiation effect to adjacent normal structures.

Success Rates Following Radio surgery

SBRT has shown dramatically better outcomes than conventional radiation therapy. Whereas two-year success rates for conventional treatment range from 30 to 40 percent, the success rates for SBRT range from 80 to 90 percent – comparable to those of resection surgery but with far fewer risks.
