QUANTITATIVE MYOCARDIAL MAGNETIC RESONANCE IMAGING METHOD AND DEVICE, AND STORAGE MEDIUM

摘要

A quantitative myocardial magnetic resonance imaging method and device, and a storage medium. Said method comprises: executing, every recovery time period, an image signal acquisition operation under the control of a cardiac gating signal and a respiratory navigation signal; determining a parameter T1 according to the acquired image signal and the delay time of a saturation pulse corresponding thereto, and determining a parameter T2 according to the acquired image signal and the delay time of a saturation pulse corresponding thereto, and the echo time interval of a T2 preparation pulse; and generating a quantitative myocardial magnetic resonance image according to the parameter T1 and the parameter T2. Said method allows the scan to be completed while the subject is breathing freely without the need to hold their breath. Moreover, said method also allows for further expansion of the imaging field and improves the spatial resolution. In addition, the completely interleaved and segmented acquisition is performed among sampling points by means of a k-space, so as to achieve intrinsic registration of the original image, without the need for additional image processing in a later stage.
