Abstract

The present application provides a magnetic resonance imaging method and device. The method comprises: controlling a magnetic resonance scan of the subject based on the equilibrium steady-state free precession bSSFP sequence; calculating a plurality of characteristic parameters of the subject based on a magnetic resonance scan result; and according to each characteristic parameter, performing themagnetic resonance scan result to obtain a magnetic resonance image corresponding to the characteristic parameter; the image contrast of the magnetic resonance image corresponding to different featureparameters is different. The technical solution of the present application can improve the magnetic resonance imaging speed and can improve the image quality of the finally obtained magnetic resonance image.

Description

technical field [0001] The present application relates to the technical field of medical imaging, in particular to a magnetic resonance imaging method and device. Background technique [0002] Magnetic resonance imaging (Magnetic Resonance Imaging, MRI) is one of the main imaging methods in modern medical imaging. Magnetic resonance imaging technology can use the signal difference of various tissues in the human body in a strong magnetic field environment to generate images and display tissue structures. Doctors provide images with various contrasts, such as: T1 (longitudinal relaxation time) weighted image, T2 (transverse relaxation time) weighted image, proton density weighted image, etc. [0003] Regardless of whether they are normal or abnormal, different tissues in the human body have their own characteristic parameters such as T1, T2 and proton density. This is the basis for using magnetic resonance imaging technology to distinguish between normal and abnormal tissues ...
