Stereotactic Radiosurgery

Stereotactic Radiosurgery

 

Stereotactic radiosurgery treats lesions which cannot be safely reached through traditional surgical means by focusing narrow dynamic arcs of radiation to controlled areas of the brain.
 

Where Sterotactic Radiosurgery Can Help

Traditional neurosurgery is still the treatment of choice. It continues to offer the best probability of curing the disorders. But stereotactic radiosurgery offers an alternative when factors such as lesion location make neurosurgery high risk.

Stereotactic radiosurgery works by delivering precise doses of radiation to exact lesion locations with minimal disturbance to healthy brain tissue. This is done by first scanning the brain to create a 3-dimensional model of the affected area and then using this information to both analyze the disorder and to program the linear accelerator.

In cases involving benign tumors and arteriovascular malformations, the procedure can be curative. With malignant tumors, it can slow their growth and extend life expectancy. It may also be used to treat matastic tumors.
 

A Typical Treatment Process

  • Placement of Stereotactic Head Frame

  • CT scans indicate lesion location

  • MRI scan (if necessary)

  • 3-D computer dosimetry provides information to further analyze lesions and program linear accelerators for radiation delivery.

  • Procedure is planned

  • Test run

  • Radiation therapy

  • Follow up with CT and/or MRI

The Demands of Stereotactic Radiosurgery

As with any type of brain treatment, stereotactic radiosurgery diagnosis and treatment must be precise. Great emphasis is placed on understanding the disorder and planning treatment with a 3-dimensional treatment planning system. Test runs fine-tune each procedure.

After radiation is administered, the patient is followed closely to monitor healing and to observe for complications. Since some patients are less tolerant of radiation than others, multiple treatments may be required.

In spite of these demands, and even though traditional surgery is still the preferred course of treatment, stereotactic radiosurgery is still proving to be quite effective and advances in its use are quite promising. With continued refinement, it may one day become the first choice of treatment.
