Magnetic resonance electrical impedance tomography at 3 Tesla field strength.
Magnetic resonance electrical impedance tomography (MREIT) is a recently developed imaging technique that combines MRI and electrical impedance tomography (EIT). In MREIT, cross-sectional electrical conductivity images are reconstructed from the internal magnetic field density data produced inside an electrically conducting object when an electrical current is injected into the object. In this ...
متن کاملHippocampal T2 hyperintensities on 7 Tesla MRI☆
Hippocampal focal T2 hyperintensities (HT2Hs), also referred to as hippocampal sulcal cavities, are a common finding on Magnetic Resonance (MR) images. There is uncertainty about their etiology and clinical significance. In this study we aimed to describe these HT2Hs in more detail using high resolution 7 Tesla MR imaging, addressing 1) the MR signal characteristics of HT2Hs, 2) their occurrenc...
متن کاملAdiabatic Magnetization Preparation Pulse for T2-contrast at 7 Tesla
Introduction: High-resolution MRI at 7T has the potential to provide tremendous improvement in the diagnosis and treatment of a wide range of neurological diseases. High-resolution T2-weighted sequences are sensitive for assessing subtle structural abnormalities associated with many of these diseases [1]. Unfortunately, conventional T2-weighted sequences, such as Fast Spin Echo (FSE), utilize a...
متن کاملParallel imaging of knee cartilage at 3 Tesla.
PURPOSE To evaluate the feasibility and reproducibility of quantitative cartilage imaging with parallel imaging at 3T and to determine the impact of the acceleration factor (AF) on morphological and relaxation measurements. MATERIALS AND METHODS An eight-channel phased-array knee coil was employed for conventional and parallel imaging on a 3T scanner. The imaging protocol consisted of a T2-we...
متن کاملUltrashort Echo Time Imaging of Cortical Bone at 7 Tesla Field Strength
Introduction MRI at ultra-high field (UHF) strength of 7 Tesla has been increasingly used and optimized for in vivo applications over the past few years. In particular, the increased signal to noise ratio (SNR) renders this new modality very attractive for imaging soft tissues in the human body. More solid or semi-solid tissues such as trabecular and cortical bone provide little to no signal in...
