Problems solved by technology

[0006] Prior art methods use radio frequency (RF) pulses and suppression bands to limit extraneous signals
However, it is difficult to set a suitable suppression band to accurately remove the signal affected by fat
In addition, there is the issue that the signal of the metabolite of interest may be reduced by applying a band of inhibition
However, generating additional MR images is inconvenient and expensive

Embodiment Construction

[0057] Certain exemplary embodiments are described in more detail below with reference to the accompanying drawings.

[0058] In the following description, the same reference numerals are used for the same elements even in different drawings. Matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of the exemplary embodiments. Therefore, it is apparent that exemplary embodiments can be carried out without those specifically defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the exemplary embodiments in unnecessary detail.

[0059] The terms used in this specification are for explaining the exemplary embodiments, not for limiting. Therefore, expressions in the singular include expressions in the plural unless the context clearly dictates otherwise. Unless otherwise defined, all terms used herein including technical or scientific terms...

Abstract

The invention provides a method and an apparatus for removing distortion by lipids from a magnetic resonance spectroscopic image. The method of removing distortion by lipids from an MR image includes obtaining an MR image including voxels, obtaining data of the voxels from the obtained MR image, estimating a lipid-related spectrum by using the obtained data, and removing the estimated lipid-related spectrum from the obtained data. The method may be used in the context of magnetic resonance spectroscopic imaging (MRSI).

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2012-0107489 filed with the Korean Intellectual Property Office on September 26, 2012, the entire disclosure of which is hereby incorporated by reference. technical field [0002] Apparatuses and methods consistent with the exemplary embodiments relate to removing distortions caused by lipids from magnetic resonance (MR) images, and more particularly, to obtaining spectra of lipid components from spectra of MR images and The spectrum of the lipid component was removed. Background technique [0003] Magnetic resonance spectroscopy (MRSI) is a method of obtaining images of a subject in a non-invasive manner to reveal the distribution of metabolites or biochemical information of body tissues. [0004] MRSI includes information about the spectra of metabolites present in each image voxel. In MRSI, the amount of metabolites of interest is much smaller than the amount of water or lipids captured by mag...
