Functional MRI in clinical neurosurgery: Preoperative planning and intraoperative navigation

MRI and DTI in Clinical Neurosurgery

This document attempts to describe the clinical practice of neurosurgery from the point of view of a computer scientist/medical engineer. I will focus on the current use of imaging technology in clinical practice and on the potential utility of diffusion tensor MRI imaging (DTI). The two main questions I have tried to answer are “How do doctors actually use MRI for neurosurgery?” and “What do d...

Intraoperative portable 0.12-tesla MRI in pediatric neurosurgery.

OBJECTIVES Intraoperative MRI (iMRI) is used mainly in the adult neurosurgical population. The main indications for iMRI usage are resection control and updated intraoperative navigation capabilities. In this paper we present our experience using this technique in children. Specific advantages of iMRI for this age group are discussed. METHODS AND RESULTS We retrospectively reviewed 31 pediatr...

Application of Intraoperative MRI in Neurosurgery for Resection Control

Methods We performed intraoperative MRI in 161 patients using a 0.2 Tesla Magnetom Open (Siemes AG, Erlangen, Germany), which is located in the radiofrequency shielded part of our ‘twin’ operating theatre. In brain tumor surgery (n=54) (46 cases of glioma located around eloquent areas and 8 cases of tumors in the lateral or third ventricle e.g. neurocytoma or subependymoma) and in surgery for t...

Functional connectivity networks for preoperative brain mapping in neurosurgery.

OBJECTIVE Resection of focal brain lesions involves maximizing the resection while preserving brain function. Mapping brain function has entered a new era focusing on distributed connectivity networks at "rest," that is, in the absence of a specific task or stimulus, requiring minimal participant engagement. Central to this frame shift has been the development of methods for the rapid assessmen...
