Abstract
In a magnetic resonance method and device for automatic differentiation of respective pixels as representing either a silicon-dominated substance, or fat-dominated tissue, or water-dominated tissue, a first magnetic resonance signal and a second magnetic resonance signal are acquired per pixel, wherein the first magnetic resonance signal per pixel is acquired at a point in time at which the phase of a magnetic resonance signal originating from water-containing tissue exhibits a phase opposite to the phase of a magnetic resonance signal originating from fat-containing tissue, and the second magnetic resonance signal is acquired per pixel at a point in time at which the phase of the magnetic resonance signal originating from water-containing tissue exhibits a phase identical to the phase of the magnetic resonance signal originating from fat-containing tissue, and the phase of a magnetic resonance signal originating from a silicon-containing substance exhibits a phase opposite to the phase of the magnetic resonance signal originating from water-containing or fat-containing tissue. A first intermediate result is determined that indicates whether the pixel represents water-dominated tissue or fat-dominated tissue on the basis of first magnetic resonance signals. A second intermediate result is determined that indicates whether the pixel represents the silicon-dominated substance on the basis of second magnetic resonance signals. The pixel is designated as representing water-dominated tissue, fat-dominated tissue or the silicon-dominated substance on the basis of the first intermediate result and the second intermediate result.
