Problems solved by technology

This acquisition method is not conducive to improving the MRI scan time
Moreover, the diffusion-weighted imaging signal and the spectral signal obtained by this method of independently collecting the diffusion-weighted imaging signal and the spectral signal are relatively discrete, so that the MRI diffusion-weighted imaging and the spectral signal cannot be completely registered, which brings troubles to clinical diagnosis

Embodiment Construction

[0055] At present, the MRI DWIM signal acquisition process and the MRI DWWS signal acquisition process are two completely independent signal acquisition processes. In this way, the MRI scanning time is the sum of the MRI DWI signal scanning time and the DWSI signal scanning time, resulting in a longer MRI signal acquisition time and lower MRI scanning efficiency.

[0056] In addition, because the MRI DWI signal acquisition process and the MRI DWSI signal acquisition process are completely independent, there is a time difference between the acquisition time of the DWIM signal and the DWSI signal, resulting in the acquisition of diffusion-weighted The imaging signal and the DWSP signal are relatively discrete, and if the patient moves during the interval between scanning the MRI DWI signal and scanning the MRI DWSI signal, it will cause the acquired MRI DWI signal and magnetic The resonance DWS signal may not come from the same body region of the patient, so that MRI DWIM and DW...

Abstract

The embodiment of the invention discloses a diffusion-weighted magnetic resonance imaging and spectral signal collection method and device. The diffusion-weighted magnetic resonance imaging and spectral signal collection method uses the effective time gap between the excitation and the collection of a diffusion-weighted magnetic resonance spectral signal, water molecule and the substance of metabolite with different frequency spectrums and binomial impulse with selectivity to stimulate characteristics of substances with different frequencies, and by applying three excitation pulses and two signal collection modules, the diffusion-weighted magnetic resonance imaging signal and a spectral signal can be collected jointly in a same signal collection sequence. The time of magnetic resonance scanning is saved and the scanning efficiency is improved. The diffusion-weighted imaging signal and the diffusion-weighted spectral signal are signals collected after one-time excitation, it is ensuredthat the two kinds of signals collected are signals from the same body part of a patient, and therefore, complete registration of diffusion-weighted imaging and diffusion-weighted spectrum can be ensured, and accurate clinical diagnosis can be ensured.

Description

technical field [0001] The present application relates to the technical field of magnetic resonance, in particular to a method and device for acquiring magnetic resonance diffusion weighted imaging signals and spectrum signals. Background technique [0002] MRI diffusion-weighted imaging (DWI) imaging provides tissue contrast different from conventional MRI (Magnetic Resonance Imaging, DWI) images, and can provide potential and unique information on the survival and development of brain tissue. It is very sensitive in showing acute cerebral infarction and differentiating it from other acute brain lesions. At the same time, it can also provide some information on lesions such as tumors, infections, trauma, and demyelination. [0003] Diffusion weighted imaging uses the random and irregular Brownian motion characteristics of water molecules in tissues for imaging. It is a non-invasive method that can detect the diffusion movement of water molecules in living tissues, and can p...
