Abstract

The invention relates to a method for acquiring a magnetic resonance fat-suppression image. The method comprises the following steps of acquiring a radio-frequency pulse angle alpha of a single radio-frequency fat saturation pulse; determining a first radio-frequency pulse angle alpha1 and a second radio-frequency pulse angle alpha2 of a dual radio-frequency fat saturation pulse through the radio-frequency pulse angle alpha of the single radio-frequency fat saturation pulse; and acquiring the fat saturation image based on the first radio-frequency pulse angle alpha1 and the second radio-frequency pulse angle alpha2 of the dual radio-frequency fat saturation pulse. With the method for acquiring the magnetic resonance fat-suppression image, the sensitivity of fat saturation uniformity to a radio-frequency emission field can be remarkably reduced. The invention also relates to a storage medium and a scanning system.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a magnetic resonance fat suppression image acquisition method, a storage medium and a scanning system. Background technique [0002] In the traditional frequency-selective fat suppression method, before the slice-selective excitation imaging, a radio frequency soft pulse with an appropriate bandwidth is applied to excite the fat signal and gradient dispersal, so that the water signal is preserved and the fat signal is suppressed. The uniformity of grease pressing is greatly affected by the unevenness of the radio frequency transmission field (ie B1), that is, the uniformity of grease pressing by traditional methods is very sensitive to B1. In T2FSE (fast spin echo) imaging, the effect of B1 inhomogeneity on fat suppression uniformity tends to be more pronounced. The B1 unevenness of the 3T system is obvious, and the uniformity of grease pressing has become a serious problem affe...
