Intraoperative Computed Tomography Guided Neuronavigation: Concepts, Efficiency, and Work Flow

Intraoperative MRI and Image-guided Frameless Neuronavigation

Neurosurgeons have long used various image-guided systems, such as fluoroscopy, ultrasound, and threedimensional (3-D) stereotaxy in an attempt to more accurately localize intracranial targets (34). The development of advanced neuroimaging techniques over the years has provided the neurosurgeon with increasingly more accurate and precise tools to aid in the microsurgical treatment of intracrani...

Intraoperative Computed Tomography/Angiography Guided Resection of Skull Base Lesions

Lung Lesions Biopsy in Children by Computed Tomography (CT) Fluoroscopy Guided Versus Conventional CT Scan Guided

Abstract Background Computed tomography (CT)-guided biopsy of the lung is a well-established method of diagnosis. The aim of this study was to determine the success rate of fluoroscopic CT (FCT) and conventional CT (CCT) in needle navigation biopsies from the lung lesions. Materials and Methods A total of 78 patients were prospectively enrolled to receive CT-guided biopsy with (group I, n=2...

Intraoperative computed tomography and automated registration for image-guided cranial surgery.

OBJECTIVES Two key problems for the use of navigation systems in image-guided surgery are accurate patient-to-image registration and the fact that with ongoing surgery the patient's anatomy is altered while the image data remains unchanged. A system for intraoperative CT imaging and fully automated registration of this image addresses both problems. It had been evaluated successfully in phantom...

Intraoperative Optical Coherence Tomography Guided Bleb Needling

Two patients with history of trabeculectomy presented with uncontrolled intraocular pressure (IOP) postoperatively. The first patient had a flat and vasularized bleb 10 weeks after the surgery, and the second subject developed encapsulated bleb 3 months postoperatively. Both patients were taken to the operating room and intraoperative optical coherence tomography (OCT) guided bleb needling was ...
