Abstract

The invention provides a myocardial quantitative magnetic resonance imaging method, equipment and storage medium. The method includes: performing an image signal acquisition operation under the control of the ECG gating signal and the respiratory navigation signal at intervals of the recovery period; determining the parameter T according to the acquired image signal and the delay time of the corresponding saturation pulse 1 ;according to the parameter T 1 Generate myocardial quantitative magnetic resonance images. This protocol allows the scan to be completed with the subject breathing freely, without the need for breath-holding. At the same time, it also allows to further expand the imaging field of view and improve the spatial resolution. In addition, segmented acquisitions are fully interleaved between sampling points via k‑space, enabling intrinsic registration of the original image without additional image processing in post.

Description

Technical field [0001] The present invention relates to the field of medical imaging, and more particularly to a cardium-quantitative magnetic resonance imaging method, apparatus, and storage medium. Background technique [0002] Nuclear magnetic resonance imaging techniques utilize nuclear magnetic resonance phenomena to human imaging, which is already a common medical imaging examination. [0003] Basic physical parameters of nuclear magnetic resonance T 1 (Self-ribs relaxation time, or a longitudinal relaxation time) is a time constant that describes the longitudinal magnetization vector recovery. T 1 The composition of the biological tissue is determined in the form of a structure and the magnetic field strength. At the determined magnetic field strength, different tissues have specific T 1 Numerical value. When the biological tissue changes, T 1 It will also change. So T 1 Myocardial tissue characteristics can be identified as feature parameters. [0004] Myocardial T in rec...
