Ethical considerations in functional magnetic resonance imaging research in acutely comatose patients
Estimating the likelihood of recovery of cognitive function in the acutely comatose patient is one of the most difficult challenges facing neurologists and critical care physicians. Coma, defined as a state of unarousable unconsciousness, is most commonly caused by traumatic brain injury and anoxia following cardiopulmonary arrest. Patient outcome after severe brain injury is highly variable (Y...

متن کاملStatic Coil Design Considerations for the Magnetic Resonance Imaging
One of the main challenges in developing magnetic resonance imaging (MRI) systems is to create a static coil that needs to generate magnetic field density along with the characteristics of optimal homogeneity and magnitude size. To do this, two N42 Block PMs are used and the iron core is designed and optimized in accordance with the dimensions of PM pieces using ANSYS Maxwell software. Then, al...
متن کاملEthical and practical considerations in managing incidental findings in functional magnetic resonance imaging.
Functional magnetic resonance imaging has emerged as a powerful tool for mapping the neurologic underpinnings of sensory, motor and cognitive function. Much of this evolution carries assumptions about the subject population under study and, in particular, the neurologic status of subjects entered into studies either as healthy controls or as belonging to a specific disease group. Recent reports...
