摘要： In a method and control system for producing two-dimensional diagnostic MR images using a magnetic resonance imaging scanner, a first three-dimensional MR image data set of a predetermined region within a body is produced using the magnetic resonance imaging scanner with an initial resolution. A second three-dimensional MR image data set of the predetermined region with a second resolution is then produced using the magnetic resonance imaging scanner, the second resolution being higher than the first resolution. Using the first three-dimensional MR image data set, layers are determined for the diagnostic two-dimensional MR images to be produced. The two-dimensional MR images are then computed from the second MR image data set for these layers automatically.

摘要： In a magnetic resonance method and system to automatically differentiate whether a pixel of an MR image acquired with magnetic resonance system originated from fat-dominated tissue or water-dominated tissue, only one spin echo-based magnetic resonance signal per pixel is acquired at a point in time at which the phase of a magnetic resonance signal of aqueous tissue has a phase opposite to the phase of a magnetic resonance signal of fat tissue. The phase angle of the pixel is then calculated, a base phase at the pixel depending on the magnetic resonance system is determined, and a corrected phase angle of the pixel is determined from the phase angle and the base phase. Whether the pixel originated from fat-dominated tissue or water-dominated tissue is then determined using the corrected phase angle of the pixel.
