UNLABELLED Transcranial magnetic resonance imaging-guided focused ultrasound (tcMRgFUS) is a novel technique to supplement the spectrum of established neurosurgical interventions. In contrast to traditional ablative procedures, tcMRgFUS is noninvasive and entirely imaging-guided with continuous temperature measurements at and around the target in real time. It has no trajectory restrictions and...
Introduction: Previously, an MRI-guided focused ultrasound (MRgFUS) system was described that aims to use transcranial ultrasound exposures to noninvasively thermally ablate targets in the brain (1-3). This system uses acoustic models, geometric and density information derived from CT scans, and a phased array transducer to correct for skull-induced aberrations of the ultrasound beam (4). Here ...
Purpose To demonstrate that magnetic resonance (MR) imaging-monitored transcranial focused ultrasound can enhance the delivery of the antiangiogenic monoclonal antibody bevacizumab into the central nervous system (CNS) for glioblastoma multiforme (GBM) treatment. Materials and Methods All animal experiments were approved by the animal committee and adhered to experimental animal care guidelines...
