This paper presents a procedure for combining MR anatomical information and a stereotactic reference obtained from a CT study with a Leksell frame attached to the patient’s head, in order to guide neurosurgery of functional disorders. MRI acquisition can be performed well before the surgery, without the stereotactic frame. The day of the intervention, after attaching the Leksell frame to the pa...

OBJECTIVES Radiological imaging techniques provide early detection of neurological diseases but they do not always provide an adequate and reliable diagnosis. With the help of stereotactic biopsy techniques, it is possible to access brain lesions safely and with high precision. We described the surgical method used in our clinic and discussed our results with the help of the current literature....

BACKGROUND Limited data describe the prognosis after stereotactic ablative radiotherapy for lung metastases arising from colorectal cancer. Thus, we evaluated treatment outcomes of stereotactic ablative radiotherapy for those patients. METHODS The study involved patients received stereotactic ablative radiotherapy for one to three lung metastases arising from colorectal cancer at a single ins...

Imaging-guided breast biopsy performed with large-core needles can accurately diagnose most breast pathologies, often allowing a diagnosis to be made more quickly and less expensively than with surgical biopsy. Major complications, such as hemorrhage and infection, are extremely rare, although post-biopsy ecchymosis and tenderness are not unusual. Because less tissue is removed, post-biopsy cos...

BACKGROUND Deep seated lesions of the brain cannot be approached by conventional neurosurgical approach stereotactic system offers minimally invasive and accurate approach to such lesions. This study was carried out with an objective to determine the safety, efficacy and diagnostic yield of stereotactic biopsies of brain lesions using Brown-Roberts-Wells (BRW) system. METHODS This study was c...

Stereotactic radiosurgery to benign tumors of the spine has not been advocated as a primary treatment modality because of the favorable prognosis for these lesions after gross-total resection. There is even less evidence regarding its use as an adjuvant to neurosurgical resection of benign recurrent spinal disease. We describe the case of a 30-year-old man with a thoracic spinal schwannoma who ...

PURPOSE Stereotactic vacuum-assisted breast biopsy (VAB) has been established as a standard method for histological diagnosis of microcalcification or nonpalpable breast lesions on mammography. Generally, the procedure has been done under the prone position or upright sitting position. We herein attempt to evaluate clinical utility of Stereotactic VAB under lateral decubitus position. METHODS...

Hypothalamic hamartomas (HH) are benign tumors that can cause significant morbidity in adults as a cause of epilepsy, particularly gelastic seizures. Open and endoscopic resections of HH offer good seizure control but have high rates of morbidity and are technically challenging. Stereotactic radiosurgery has been an alternative treatment; however, it results in comparably poor seizure control. ...

The role of stereotactic radiosurgery in the management of recurrent and newly diagnosed brain metastases was evaluated prospectively. From December 1988 to March 1991, 58 lesions in 40 patients were treated with accelerator-based stereotactic radiosurgery. All patients were followed for a minimum of 6 months or to death. The primary purpose was to determine the impact of radiosurgery on local ...
