Abstract

The invention relates to a magnetic resonance imaging method and device, computer equipment and a storage medium. The method comprises the following steps: detecting an R wave in a single breath-holding process, and applying a reversal pulse after the R wave is detected, so that a longitudinal magnetization vector is reversed; in N cardiac cycles of the longitudinal magnetization vector recovery process, performing at least two times of image acquisition in each cardiac cycle according to preset recovery time to obtain a plurality of scanning images; wherein N is a positive integer; and obtaining a T1 image according to the plurality of scanning images. By adopting the method, the breath-holding time of the scanned object can be reduced.

Description

technical field [0001] The present application relates to the technical field of magnetic resonance imaging, in particular to a magnetic resonance imaging method, device, computer equipment and storage medium. Background technique [0002] Cardiac Magnetic Resonance Imaging (CMRI) has good tissue contrast and is non-invasive and harmless to the human body. It has been widely used in the evaluation of the shape, function and tissue characteristics of the heart in recent years. Myocardial longitudinal relaxation time will change accordingly when the myocardial water content and extracellular environment change. The longitudinal relaxation time quantitative imaging (T1 mapping) technology can quantitatively reflect the tissue characteristics of the myocardium. The diffuse lesions such as myocardial edema, fibrosis, fatty infiltration and iron deposition were detected by quantitative measurement of the initial T1 value and the T1 value after injection of contrast medium.
