Intraoperative MR and Synthetic Imaging

Serial Intraoperative MR Imaging of Brain Shift

Introduction: The major shortcoming of image-guided navigational systems is the use of presurgically acquired image data, which does not account for intraoperative changes in brain morphology. The occurrence of these surgically induced volumetric deformations, or "brain shift", has been well established. Maximum measurements for surface and midline shifts were reported. There is no detailed ana...

Patient Safety on intraoperative MR Imaging in a two room

As early as 1997 the first clinical publications showed the clinical benefits of using intra-operative Magnetic Resonance Imaging: “Intra-operative MRI can be expected to increase the degree and accuracy of resection” . Other studies have looked at post-operative MRI imaging and indicate that intra-operative MRI would have had an influence on the clinical outcome . All recent studies concur tha...

Quantifying the intraoperative brain deformation using interventional MR imaging

The increasing use of image guided surgery systems for neurosurgery has lead to considerable recent interest in quantifying brain deformation during neurosurgery, Traditional image guided neurosurgery systems determine the rigid body transformation between pre-operative images and an intraoperative coordinate system (eg.: defined by an optical localiser). These systems can be very accurate, esp...
