Download or read book Magnetic Resonance Imaging in Deep Brain Stimulation written by Alexandre Boutet and published by Springer Nature. This book was released on 2022-11-28 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the roles magnetic resonance imaging (MRI) can play in deep brain stimulation (DBS). DBS therapeutically modulates aberrant neural circuits implicated in a broad range of neurological disorders. Following surgical insertion, an electrode placed into the desired brain target generates constant electricity, analogous to a cardiac pacemaker. Most commonly employed in movement disorders such as Parkinson’s disease, dystonia, and tremor, DBS is also being investigated for use in psychiatric and cognitive disorders, including depression and Alzheimer’s disease. It is estimated that more than 230,000 patients have undergone DBS surgery worldwide. Imaging techniques, specifically MRI, have played key roles in the preoperative and postoperative aspects of DBS. This book focuses on the established as well as the innovative roles of MRI in DBS. MRI and DBS are first introduced from an historical perspective and a review of the clinical aspects of DBS is performed. Then, the preoperative and postoperative applications of MRI in DBS are covered. The crucial aspect of MRI safety in these patients is also discussed. Finally, possible upcoming MRI applications for patients with DBS are discussed in a future directions chapter. Chapters are written by experts from the University of Toronto, a world leader in the field of DBS, alongside international co-authors to ensure a thorough review of the topics. This is an ideal guide for both clinicians (neurosurgeons, neurologists, psychiatrists, and neuroradiologists) and researchers as well as trainees interested in neuroimaging for DBS.

Available in PDF, EPUB and Kindle. Book excerpt: Magnetic resonance imaging (MRI) has become the standard of care for the evaluation of different neurological disorders of the brain and spinal cord due to its multiplanar capabilities and excellent soft tissue resolution. With the large and increasing population of patients with implanted deep brain stimulation (DBS) devices, a significant proportion of these patients with chronic neurological diseases require evaluation of their primary neurological disease processes by MRI. The presence of an implanted DBS device in a magnetic resonance environment presents potential hazards. These include the potential for induction of electrical currents or heating in DBS devices, which can result in neurological tissue injury, magnetic field-induced device migration, or disruption of the operational aspects of the devices. In this chapter, we review the basic physics of potential interactions of the MRI environment with implanted DBS devices, summarize results from phantom studies and clinical series, and discuss present recommendations for safe MRI in patients with implanted DBS devices.

Download or read book Brain Stimulation written by Ji Hyun Ko and published by Elsevier Inc. Chapters. This book was released on 2013-11-11 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of functional brain imaging techniques, including positron emission tomography (PET), single-photon emission computed tomography (SPECT), and functional magnetic resonance imaging (fMRI), has allowed for monitoring neuronal and neurochemical activities in the living human brain and identifying abnormal changes in various neurological and psychiatric diseases. Combining these methods with techniques such as deep brain stimulation (DBS) and transcranial magnetic stimulation (TMS) has greatly advanced our understanding of the effects of such treatment on brain activity at targeted regions as well as specific disease-related networks. Indeed, recent network-level analysis focusing on inter-regional covarying activities in data interpretation has unveiled several key mechanisms underlying the therapeutic effects of brain stimulation. However, non-negligible discrepancies have been reported in the literature, attributable in part to the heterogeneity of both imaging and brain stimulation techniques. This chapter summarizes recent studies that combine brain imaging and brain stimulation, and includes discussion of future direction in these lines of research.

Download or read book Fusion of Multimodal Neuroimaging for Deep Brain Stimulation Studies written by Dustin T. Cunningham and published by . This book was released on 2012 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Deep brain stimulation (DBS) represents a promising therapy for neurological and psychiatric disorders. The use of multimodal neuroimaging may help elucidate the mechanisms of DBS on the brain and improve clinical outcome. However, DBS provides certain challenges to neuroimaging. Magnetic resonance imaging (MRI) is used before the electrodes are implanted to gain structural and functional information in the brain. Due to the contraindication of metallic implants at 3T MRI, computed tomography (CT) is used to determine the final electrode positions and positron emission tomography (PET) is used to gain functional data. The goal of this thesis is to research and implement a software solution to the challenges of neuroimaging in DBS research. A software tool is created to combine structural and diffusion MRI with electrode locations from CT and allow for longitudinal integration with PET. This tool is tested on a severe traumatic brain injury patient who has undergone DBS surgery. It is shown how the unique and complementary information from multimodal neuroimaging is processed and combined with minimal input from the user. This tool can be used in future research studies to aid in understanding the effects of DBS and help gain insight into the complexities of the human brain.
Download or read book Models and Simulations of the Electric Field in Deep Brain Stimulation written by Fabiola Alonso and published by Linköping University Electronic Press. This book was released on 2018-09-10 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deep brain stimulation (DBS) is an established surgical therapy for movement disorders such as Parkinson’s disease (PD) and essential tremor (ET). A thin electrode is implanted in a predefined area of the brain with the use of stereotactic neurosurgery. In the last few years new DBS electrodes and systems have been developed with possibilities for using more parameters for control of the stimulation volume. In this thesis, simulations using the finite element method (FEM) have been developed and used for investigation of the electric field (EF) extension around different types of DBS lead designs (symmetric, steering) and stimulation modes (voltage, current). The electrode surrounding was represented either with a homogeneous model or a patient-specific model based on individual preoperative magnetic resonance imaging (MRI). The EF was visualized and compared for different lead designs and operating modes. In Paper I, the EF was quantitatively investigated around two lead designs (3389 and 6148) simulated to operate in voltage and current mode under acute and chronic time points following implantation.Simulations showed a major impact on the EF extension between postoperative time points which may explain the clinical decisions to change the stimulation amplitude weeks after implantation. In Paper II, the simulations were expanded to include two leads having steering function (6180, Surestim1) and patient-specific FEM simulations in the zona incerta. It was found that both the heterogeneity of the tissue and the operating mode, influence the EF distribution and that equivalent contact configurations of the leads result in similar EF. The steering mode presented larger volumes in current mode when using equivalent amplitudes. Simulations comparing DBS and intraoperative stimulation test using a microelectrode recording (MER) system (Paper III), showed that several parallel MER leads and the presence of the non-active DBS contacts influence the EF distribution and that the DBS EF volume can cover, but also extend to, other anatomical areas. Paper IV introduces a method for an objective exploitation of intraoperative stimulation test data in order to identify the optimal implant position in the thalamus of the chronic DBS lead. Patient-specific EF simulations were related to the anatomy with the help of brain atlases and the clinical effects which were quantified by accelerometers. The first results indicate that the good clinical effect in ET is due to several structures around the ventral intermediate nucleus of the thalamus.
