Magnetic resonance imaging method and device, storage medium and electronic device

Abstract

The present invention relates to a magnetic resonance imaging method and device, a storage medium and an electronic device, and aims to reduce data acquisition time in a magnetic resonance imaging process, realize faster magnetic resonance imaging and improve magnetic resonance imaging quality. The magnetic resonance imaging method comprises the following steps: based on a three-dimensional spoiled gradient echo sequence, acquiring downsampling K space feature data with different contrasts through a K space variable density interleaved sampling mode; inputting the downsampling K space featuredata into a multi-parameter quantitative network model which bases on the downsampling K space feature data to reconstruct to obtain images corresponding to complete K space feature data with different contrasts, and obtaining a plurality of parameter quantitative images according to the images corresponding to the complete K space feature data; and determining a plurality of the parameter quantitative images output by the multi-parameter quantitative network model as magnetic resonance imaging results.

Description

technical field [0001] The present disclosure relates to the technical field of medical imaging, and in particular, to a magnetic resonance imaging method, device, storage medium and electronic equipment. Background technique [0002] Magnetic resonance imaging (Magnetic Resonance Imaging, MRI) is one of the main imaging methods in modern medical imaging. Its basic working principle is to use the magnetic resonance phenomenon to excite the hydrogen protons in the object to be detected, and use the gradient field to encode the position. The receiving coil is used to receive the signal with position information, and finally the image information is reconstructed through Fourier transform. Among them, MRI quantitative imaging can change some physiological indicators from traditional contrast to quantitative value description, so as to perform quantitative evaluation. [0003] However, the MRI quantitative imaging method needs to collect a series of data, such as multiple echoe...

Problems solved by technology

[0003] However, the MRI quantitative imaging method needs to collect a series of data, such as multiple echoes, multiple flip angles or multiple phases, and then use the collected data to fit the signal model and then obtain quantitative values, which usually requires a long acquisition time , that is, the acquisition time will exceed the breath-holding time of the detected object, which will cause respiratory motion artifacts in the imaging results, which will affect the imaging quality
