Magnetic Resonance Im Spectral resolution enhancement by chemical shift imaging
Three-dimensional chemical shift imaging (3D CSI) with appropriate data postprocessing can be used as a tool to improve spectral resolution in samples where large susceptibility differences and limited shim capabilities prevent good sample shimming. Data postprocessing is reduced to the realignment of individual 3D voxel spectra. As a result, the line broadening due to the field inhomogeneity o...
متن کاملChemical shift magnetic resonance imaging of human atheroma.
Fifteen necropsy specimens of human descending aorta and from eight patients with atheromatous vascular disease were studied by magnetic resonance imaging at 0.5 T. Images were acquired in coronal and transverse planes to localised protruding lesions and then chemical shift imaging was performed by techniques described by Dixon and by Hinks. These techniques produce images in which signal stren...

متن کاملNuclear magnetic resonance imaging
This review covers the progress in the field of NMR imaging (NMRI), NMR microimaging, NMR microscopy or MR (micro) tomography as well as MRI (Magnetic Resonance Imaging) over a period from June 2005 to may 2006 and is a continuation of the report from last year. The word ‘‘MRI’’ was used mostly in the medical or clinical field, but recently many authors in non-medical field uses ‘‘MRI’’ instead...
