Proton magnetic resonance spectroscopy (1H-MRS) provides specific metabolic information not otherwise observable by any other imaging method. 1H-MRS of the brain at 3 T is a new tool in the modern neuroradiological armamentarium whose main advantages, with respect to the well-established and technologically advanced 1.5-T 1H-MRS, include a higher(More)
Introduction: Computer simulations for MRI tend to focus on different application areas. Traditionally, design of MR system components, such as the main magnet, gradients and RF coils is done using the finite-difference time-domain (FDTD) [1] and finite element (FEM) [2] methods. In doing so, certain generic specifications are followed in the belief that(More)
PURPOSE To compare an external sensor-based k-space calibration technique with a routine precalibration method for quantification of method accuracy and reduction of spiral imaging artifacts to obtain improved image quality. MATERIALS AND METHODS Recently, magnetic field monitoring (MFM) has been introduced as a new calibration technique of gradient(More)
