3D RADIOTHERAPY

It is a method that seeks to precisely adapt the treatment to the tumor volume and uses the modern tomography and magnetic resonance equipment that the Abreu clinic has, three-dimensional planning systems and the linear accelerator thanks to joint work.

RADIOSURGERY

A few years ago it was unimaginable to think that cranial surgery could be performed without the need to open the patient's skull, today there are more than 600 procedures performed in the country thanks to the Intracranial Radiosurgery technique.

Radiosurgery is a special irradiation technique in which high doses are administered using a stereotaxic coordinate system, with sub-millimeter precision over a small volume. It merits the placement of a stereotaxic frame for the location of the tumor, which can be treated in a single session or by hypofractionating the treatment up to 5 sessions using a mask or Byte Block type immobilizer.

The dose is administered through radiation arcs with millimeter cones or multileaf collimators, installed in the CLINAC 21 IX linear accelerator and in the HALCYON accelerator.

This treatment modality is used in benign and malignant brain tumors: meningiomas, neurinomas or acoustic schwannomas, pituitary tumors, gliomas in their different varieties and subtypes, various tumors in the cranial base. It is also used to treat functional disorders such as trigeminal neuralgia; and for the treatment of arteriovenous malformations (AVM), cavernous angiomas
