AI Technical Summary

Technical Problem

In the prior art, magnetic resonance cardiac delay enhancement imaging and magnetic resonance coronary imaging require magnetic resonance scanning separately, resulting in the problem of long scanning time and low efficiency.

Method used

In a single magnetic resonance scan, by collecting the first K spatial data and the second K spatial data within the same cardiac cycle, a cardiac delay enhancement image and coronary artery image are generated, and the ECG R wave delay time and inversion recovery preparation pulse are used to collect data in combination with a stationary period within the cardiac cycle.

Benefits of technology

It is realized that two images are generated simultaneously in a single magnetic resonance scan, reducing the number of scans and improving imaging efficiency.

Abstract

The present application relates to a magnetic resonance imaging method, apparatus, and device, wherein the magnetic resonance imaging method is used to generate a first image and a second image in a single magnetic resonance scan; the method comprises: acquiring a myocardial signal of a scanned patient, the myocardial signal comprising multiple consecutive cardiac cycles; determining a first acquisition period and a second acquisition period within the same cardiac cycle, acquiring first K-space data of a region of interest of the scanned subject during the first acquisition period, and acquiring second K-space data of a region of interest of the scanned subject during the second acquisition period; generating a first image based on the first K-space data, and generating a second image based on the second K-space data. This application solves the problem in the prior art that a single magnetic resonance scan can only complete one type of K-space data acquisition and generate one type of magnetic resonance image, reduces the number of magnetic resonance scans, and has the technical effect of higher image generation efficiency.
