摘要：The present invention relates to an MR imaging method of a patient's body10.It is an object of the present invention to provide a method of reducing a
contrasthobler in propeller imaging combined with multiple echo acquisition.The methodof the present invention isAt least part of the bodyGenerating an MR signal by exposing aplurality of RF pulses and an MR imaging sequence including a switching magnetic fieldgradient to the MR imaging sequenceThe step of acquiring the MR signal as a plurality ofk-space blades continuously in time according to the propeller scheme;Each k space
blade isIncludes multiple substantially parallel k-space linesK space bladeK centeredaround the center of the spaceAndThe entire data set of the MR signals isSpan at least aportion of the circle of K spaceThe common central circular region of K space isCoveredby all k space bladesThe relaxation enhancement of the MR signal isChange betweenindividual different k-space bladesAndEstimation of relaxation enhancement of MRsignalsAccording to the estimated relaxation enhancementTo compensate for theacquired MR signal andHow to reconstruct MR images from compensated MR signals.Thepresent invention relates to a computer program for an MR apparatus 1 and an MRapparatus 1.
