摘要
集成磁共振成像(Synthetic Magnetic Resonance Imaging,SyMRI)技术是一种新兴磁共振成像技术,可通过一次扫描完成对全脑T1、T2弛豫时间及质子密度的定量分析,并基于定量数据实现多种对比加权图像重建、自动脑组织分割及体积测量。本文将介绍SyMRI技术的基本原理及功能,回顾SyMRI技术在颅脑疾病诊断中的应用进展,总结其优势和局限性,为今后SyMRI技术在颅脑疾病诊疗中的应用研究和推广提供参考。
Synthetic magnetic resonance imaging(SyMRI)is a new magnetic resonance imaging technology,which complete the quantitative analysis of T1 and T2 relaxation time and proton density of the whole brain through one scan,and based on quantitative data to achieve a variety of contrast weighted image reconstruction,automatic brain tissue segmentation and volume measurement.This paper will introduce the basic principle and function of SyMRI technology,review the application progress of SyMRI technology in the diagnosis of craniocerebral diseases,summarize its advantages and limitations,It aims to provide reference for the application research and promotion of SyMRI in the diagnosis and treatment of craniocerebral diseases in the future.
