Problems solved by technology

However, in the related art, if multiple different types of magnetic resonance images of a subject need to be used for diagnosis, it is necessary to perform multiple magnetic resonance scans on the subject to obtain these different types of magnetic resonance images , so the MRI scan time is longer and the MRI efficiency is lower

Abstract

The invention provides a magnetic resonance imaging method and device. The method comprises the steps that output RF pulses are controlled to excite a testee; magnetic resonance imaging data of the testee in a plurality of different echo time is separately acquired; based on the magnetic resonance imaging data, a first type of magnetic resonance images sensitive to whole tissue and a second type of magnetic resonance images sensitive to long T2 tissue are obtained. The magnetic resonance imaging method and device have the advantages that magnetic resonance scanning is carried out on the testeeonly once to obtain a plurality of different types of magnetic resonance images of the testee, so that the magnetic resonance scanning frequency is reduced and the magnetic resonance imaging efficiency is also improved.

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] As a multi-parameter, multi-contrast imaging technique, Magnetic Resonance Imaging (MRI) is one of the main imaging methods in modern medical imaging, which can reflect tissue T1 (longitudinal relaxation time), T2 (transverse relaxation It provides information for disease diagnosis. The basic working principle of magnetic resonance imaging is to use the magnetic resonance phenomenon, use radio frequency pulses to excite hydrogen protons in the human body, and use gradient fields for position encoding, then use receiving coils to receive electromagnetic signals with position information, and finally use Fourier transform to reconstruct MRI images. [0003] Different tissues in the human body usually have different T2 parameters. For example, cartilage and Achilles tendon belong to sho...
