Stereotactic Radiotherapy / Radiosurgery of brain tumors

This elaborate treatment technique is also known as high-precision radiation therapy. Prerequisite is the rigid fixation of the patient's head by means of a close-fitting mask. Thereby a good reproduction of the planned head position during irradiation is accomplished.

For treatment planning images from a computed tomography examination and additionally from pre-treatment magnetic resonance imaging for target volume definition are employed. 

During irradiation the device rotates around the head while the beam shaping elements permantly conform to the shape of the tumor (dynamic arcs). Thereby surrounding tissues and sensitive orgens can optimally be spared.

In "fractionated stereotactic radiotherapy" the desired dose is applied in conventional single doses during several weeks. This procedure is applied preferentially in benign tumors, especially if they are situated close to organs at risk.

In larger brain metastases, malign brain tumors (e.g. glioblastomas) that have already been irradiated or certain benign tumors like acoustic neuromas, few stereotactic sessions during a period of one week may be reasonable.

In contrast to fractionated treatment, in stereotactic single fraction irradiation radiation dose is applied in a single radiation session with very high dose. This procedure called radiosurgery, though not interconnected with a surgical interference is often employed in small brain metastases and is in most cases capable of stopping their growth.
