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...

AIM Computed tomography (CT)-guided stereotactic brain biopsy has been performed in our clinic since March 1998. In this prospective study, we examined the patient data undergoing stereotactic biopsy and the results of biopsies in 500 consecutive patients. MATERIAL AND METHODS Between the dates of March 1998 and January 2015, CT-guided stereotactic biopsies were performed by using the Leksell...

The purpose of the study was to investigate possible differences in the survival and outcome of malignant brain glioma patients when treated by two different methods of surgery. During a 3-year period, 32 glioma patients underwent surgery and oncological protocol afterwards. The patients were divided into two groups according to the surgical method applied. The case group comprised 11 patients ...

Objective: To evaluate the accuracy of stereotactic coal injection and wire localisation followed by excisional biopsy for occult breast lesions. Experimental design: Prospective study Setting: University Hospital Patients: Forty-five patients with abnormal mammographic findings out of 6543 women undergoing screening mammography. Patients with palpable or ultrasonographically detectable lesions...

Thirty five patients presenting with epilepsy alone and non-enhancing low-density lesion on the CT scan underwent a computer-assisted CT-guided stereotactic biopsy with stereotactic angiographic control. There was no mortality or morbidity in this series and the diagnostic yield was 97%. Thirty four patients had low grade intra-axial neoplasms. After an estimation of the pathological extent of ...

The aim of the present case study was to investigate the advantages of intraoperative magnetic resonance imaging (iMRI) on the real-time guidance and monitoring of a stereotactic biopsy. The study describes a patient with intracranial lesions, which were examined by conventional MRI and diffusion tensor imaging using a 1.5T intraoperative MRI system. The digital and pre-operative positron emiss...

BACKGROUND The authors evaluated outcomes and treatment costs of stereotactic core needle biopsy (SCNB) and ultrasound core needle biopsy (UCNB), and needle localization biopsy (NLB) in managing patients with mammographic abnormalities presenting to the surgeon. METHODS Data for all patients with mammographic lesions who underwent SCNB or UCNB since their introduction at this institution were...

BACKGROUNDS Neuroendoscopic biopsy is one of the techniques that can be used for histological verification of a suspected brain tumor. The use of neuroendoscopy is particularly useful for cystic tumors and para- and intraventricular brain tumors that are risky for stereotactic biopsy. The technique of navigated neuroendoscopy enables biopsy sampling under visual control, haemostasis of biopsy s...

Sun et al. have invented a new stereotactic instrument[1], which is thought to bridge the differences between frameless and frame-based techniques. It consists of a stereotactic frame, which is attached to the skull in a manner comparable to classical stereotactic frames. Instead for guidance of a linear instrument, as for example in the case of a frame-based stereotactic biopsy, it is connecte...

OBJECTIVE The purpose of this study is to evaluate the clinical utility of adding lateral approach to conventional vertical approach for prone stereotactic vacuum-assisted breast biopsies. MATERIALS AND METHODS From April 2010 to May 2012, 130 vacuum-assisted stereotactic biopsies were attempted in 127 patients. While a vertical approach was preferred, a lateral approach was used if the verti...
