MREIT conductivity imaging of canine head using multi-echo pulse sequence
In magnetic resonance electrical impedance tomography (MREIT), we measure induced magnetic flux densities subject to multiple injection currents to reconstruct crosssectional conductivity images. Spin echo pulse sequence has been widely used in MREIT and produce postmortem and in vivo conductivity images of animal and human subjects. The image quality depends on the SNR of the measured magnetic...
متن کاملOptimization of magnetic flux density for fast MREIT conductivity imaging using multi-echo interleaved partial fourier acquisitions
BACKGROUND Magnetic resonance electrical impedance tomography (MREIT) has been introduced as a non-invasive method for visualizing the internal conductivity and/or current density of an electrically conductive object by externally injected currents. The injected current through a pair of surface electrodes induces a magnetic flux density distribution inside the imaging object, which results in ...
متن کاملDynamic Susceptibility Contrast Imaging using a multi-echo spiral sequence
Introduction To characterize microvasculature, one can perform a DCE-MRI experiment (a first injection of contrast agent (CA) to estimate the vessel wall permeability) followed by a DSC-MRI experiment (a second injection of CA to estimate relative blood volume (rCBV), relative blood flow, etc.) [1]. The DSC experiment can even yield information on vessel size if a gradient echo and a spin echo ...
متن کاملNumerical Simulations of MREIT Conductivity Imaging for Brain Tumor Detection
Magnetic resonance electrical impedance tomography (MREIT) is a new modality capable of imaging the electrical properties of human body using MRI phase information in conjunction with external current injection. Recent in vivo animal and human MREIT studies have revealed unique conductivity contrasts related to different physiological and pathological conditions of tissues or organs. When perfo...
متن کاملElectrical conductivity imaging by magnetic resonance electrical impedance tomography (MREIT).
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 subject when an electrical current is injected into the subject. In thi...
