UNLABELLED The aim of the present study was to determine the clinical feasibility of integration of stereotactic SPECT (sSPECT) with 201Tl in the stereotactic MRI (sMRI)-based planning of brain tumor biopsy. Furthermore, the predictive value of the integrated techniques was analyzed by comparison with the corresponding histologically determined metabolic activity. METHODS Ten patients underwe...

This study investigates the detection rate of nonpalpable, isoechoic occult prostate malignancy using a stereotactic transperineal prostate biopsy (STPB) technique in patients with a previously negative transrectal ultrasound-guided prostate biopsy.

OBJECTIVE To evaluate the diagnostic yield, accuracy, and safety of frame-based stereotactic brain biopsy procedures. METHODS A retrospective study of all pathologically diagnosed intracranial lesions, using frame-based stereotactic guided brain biopsy procedures performed at King Faisal Specialist Hospital and Research Centre (KFSH&RC), Riyadh, Kingdom of Saudi Arabia between 1993 and 2005 w...

OBJECT Stereotactic biopsy procedures are an everyday part of neurosurgery. The procedure provides an accurate histological diagnosis with the least possible morbidity. Robotic stereotactic biopsy needs to be an accurate, safe, frameless, and rapid technique. This article reports the clinical results of a series of 100 frameless robotic biopsies using a Medtech ROSA device. METHODS The author...

PURPOSE To determine the frequency with which ultrasonographically (US) guided core biopsy obviated diagnostic surgical biopsy of nonpalpable breast masses, to calculate the cost savings of diagnosis attributable to US-guided core biopsy, and to compare the costs of US-guided versus stereotactically guided core biopsy. MATERIALS AND METHODS US-guided core biopsy was performed in 151 consecuti...

Fifty-one patients with supratentorial glioma treated with external beam radiotherapy (median dose 59.5 Gy) who then demonstrated clinical or radiographic evidence of disease progression underwent stereotactic biopsy to differentiate tumor recurrence from radiation necrosis. The original tumor histological type was diffuse or fibrillary astrocytoma in 21 patients (41%), oligodendroglioma in 13 ...

A comparison study is presented, which examines the outcome, complications and cost of stereotactic brain biopsy performed with a frameless versus a frame-based method. The technique of frameless stereotactic biopsy has been shown previously, in both laboratory and in vivo studies, to achieve a level of accuracy at least equal to frame-based biopsy. The investigators have validated the techniqu...

Computerized tomography assisted Stereotactic biopsy technique using Leksell stereotactic frame was performed on 27 patients with small, multiple and deep seated brain tumours. There were 19 men and 8 women with an age range from 17 to 65 years. Histological diagnosis of 18 glial tumours, 9 non-glial tumours (5 colloid cysts, 4 metastatic lesions) was obtained. There was no mortality and minima...

Deep brain stimulation (DBS) has been shown to be a safe and effective method for the treatment of refractory Parkinson's disease and other movement disorders. Traditionally, frame-based stereotactic have been the standard technique commonly used for DBS surgery. With the development of image-guided neurosurgical systems, frameless stereotactic has been increasingly used for tumor resection or ...
