Method and apparatus for determining dephasing factors in magnetic resonance imaging and spectroscopy

摘要

In a method and apparatus for determining time-dependent dephasing factors of at least one spectral component of at least two spectral components in a region of interest in an object under examination, measured data of the region of interest and acquired over time by a test measurement in a magnetic resonance scanner. The contribution of at least one of the at least two spectral components in the recorded measured data is determined. Dephasing factors of the at least one spectral component are determined on the basis of the contribution determined therefor in the recorded measured data over time. Dephasing factors determined in this way can be determined individually with relatively little effort and used in Dixon techniques.
