Rapid heart - controlled nuclear magnetic resonance - detecting with improved t1 - contrast

摘要

A method for operating a nuclear magnetic resonance - detecting device, in order to nuclear magnetic resonance - data to produce an image of an object to detect having improved contrast, comprising the steps of:a) applying a polarization magnet field by means of the device;b) application of an acceleration - - high frequency field (210) to the object, with a tilting - angle in the range of 60° to 140°,c) performing a disdaq - pulse sequence (212) through the apparatus, the application of a high frequency - field at the object, with a tilting - angle of less than the tilting - angle of the acceleration - - high frequency field contains,d) performing a series of nuclear magnetic resonance - measurements (214) by means of the device, in which a transverse magnetization by means of a high frequency excitation - - field (21) is generated and, as a result of the generated transverse magnetization a nuclear magnetic resonance - signal is detected, ande) operation of the nuclear magnetic resonance - device for reconstructing an image from the detected nuclear magnetic resonance - signals (161).
