BACKGROUND Stereotactic radiosurgery uses a single fraction high dose radiation while stereotactic radiotherapy uses multifractionated lower dose focused radiation. MATERIALS AND METHODS Radiosurgery used rigid CRW head frame while stereotactic radiotherapy utilized GTC or HNL relocatable frames. Stereotactic planning and radiation involved Radionics X-plan and LINAC system. RESULTS Since D...

Initial experience with a new arc-radius design of stereotactic frame that interfaced with the existing components of the Brown-Roberts-Wells instrument is reported. Over a 6-month period, 32 procedures were performed on 23 males and nine female patients (mean age 32 years); these included 27 stereotactic biopsy procedures, two stereotactic implantations of cyst catheter reservoirs, two ventric...

Stereotactic radiosurgery and fractionated stereotactic radiotherapy represent an increasingly important option in the treatment of central nervous system disease. In this article, we discuss indications for stereotactic radiosurgery and review results reported in the medical literature.

"Stereotactic" is an exact radiotherapy treatment modality which implements invasive and non-invasive facilities for improving precise dose delivery. Stereotactic refers to three-dimensional localization of a specific point in space by a unique set of coordinates that relate to a fixed external reference frame. An accurate delivery of radiation is attainable using these techniques with high pre...

Introduction:  Stereotactic  radiosurgery  is  a  technique  for  the  treatment  of  intracranial  lesions  with  highly  collimated  x-ray  beam.  Linac-based  radiosurgery  is  currently  performed  by  two  techniques:  couch or pedestal mounted. In the first technique, a device is required to affix patient's head to a couch  and  moreover  to  translate  it  accurately.  Structure  of  suc...

Background and Aim: Numerous efforts over the past century have been performed. Various innovation techniques are increasingly gaining attention and gradually established the foundation of recent significant developments in the world of neurosurgery, among which varied stereotactic neuro-navigation designs and other novel emerging systems are being quotidian developed. This narrative review ai...

The use of increasingly precise, intelligent neurosurgery instruments that allow intraoperative accuracy, visualization, surgical access, has led to mastery of surgical techniques and the transformation of prognosis, the Mayfield three-pin skull clamp was designed to rigidly affix a patient's head to the operating table during craniotomy drilling and delicate microneurosurgery. However, these i...

OBJECTIVES Stereotactic biopsy is a suitable method for sampling intrinsic brain lesions. Although this method is considered to be a safe procedure, some risk of complications still exists. The aim of the study was to retrospectively assess the morbidity and mortality of MRI-guided stereotactic biopsy of lesions which were histologically proven to be brain lymphoma. METHODS We retrospectively...
