Abstract
Magnetic resonance imaging (MRI) has been widely applied in biological research and diagnostics. The chemical shift magnetic resonance imaging technique is a sequence of matrix with one spectroscopic and two spatial dimensions. This technique allows for the determination of chemical composition as well as the spatial information of the specimen and therefore it is an efficient tool to assess internal characteristics of various biological tissues. This paper introduces the process of acquiring chemical shift images of selected biological tissues and the determinations of imaging parameters for spectral images of optimum quality. An image analysis software was developed and image analysis algorithms such as image segmentation, pseudo-color processing, and image fusion were established for the analysis of spectral images. The software allows for displaying the acquired data either as a set spectrum representing the chemical composition of each pixel, or image slices representing the spatial distribution of an individual component. The efficacy of chemical shift imaging is demonstrated in this research with quantitative analysis of lean and fat portions of animal tissues.
