![]() ![]() Our ALE results showed brain regions for processing visual perception across the five categories, as well as areas of conjunction and specification. ![]() Next, based on the resulting ALE maps, the atrophy of HLV cortices in AD and MCI patients was evaluated using voxel-based morphometry. Based upon activation likelihood estimation (ALE), brain regions responsible for processing five categories of visual perceptions included in "what" and "where" visions (i.e., object, face, word, motion, and spatial visions) were analyzed, and subsequent contrast analyses were performed to show regions with conjunctive and specific activations for processing these visual functions. This study provides a functionally sorted overview of HLV cortices for processing "what" and "where" visual perceptions and it investigates their atrophy in AD and MCI patients. Moreover, the neurobiology of declined HLV functions in patients with Alzheimer's disease (AD) has not been fully investigated. Explain the workflow of invasive procedures performed within the MRI environment.The human cortical regions for processing high-level visual (HLV) functions of different categories remain ambiguous, especially in terms of their conjunctions and specifications. ![]() Describe the imaging methods used for procedural guidance and Describe the specialized hardware used during common MRI-guided interventions MRI researchers interested in how MRI can used in the context of image-guided invasive procedures.Īs a result of attending this course, participants should be able to: This includes imaging methods, MRI hardware, and specialized hardware required for MRI-guided interventional procedures. This course is intended to provide an overview of the engineering requirements for MRI-guided interventional procedures. Procedures can be diagnostic, such as cardiac catheterization or biopsy, or therapeutic, such as ablation. In MRI-guided interventions, a patient undergoes a procedure while inside the bore of the MRI scanner, and images are used to provide real-time feedback throughout the course of the procedure. In addition to diagnostic imaging, MRI also plays a role in real-time guidance of invasive procedures. ![]()
