摘要

肝脏铁浓度（LIC）的精确量化可通过磁共振成像（MRI）实现。肝脏T2*/R2*图由市场上销售的、供应商提供的三维（3D）多回波迪克森序列提供，可自动进行在线后处理，无需进行基于传统二维（2D）梯度回波（GRE）的人工曲线拟合。我们研究的主要目的是探讨三维多回波 Dixon 序列生成的 LIC 估计值与作为参考标准的基于二维 GRE 的 R2* 弛豫测量法生成的值之间的关系。

Can Automated 3-Dimensional Dixon-Based Methods Be Used in Patients With Liver Iron Overload?

Accurate quantification of liver iron concentration (LIC) can be achieved via magnetic resonance imaging (MRI). Maps of liver T2*/R2* are provided by commercially available, vendor-provided, 3-dimensional (3D) multiecho Dixon sequences and allow automated, inline postprocessing, which removes the need for manual curve fitting associated with conventional 2-dimensional (2D) gradient echo (GRE)-based postprocessing. The main goal of our study was to investigate the relationship among LIC estimates generated by 3D multiecho Dixon sequence to values generated by 2D GRE-based R2* relaxometry as the reference standard.

期刊介绍： The mission of Journal of Computer Assisted Tomography is to showcase the latest clinical and research developments in CT, MR, and closely related diagnostic techniques. We encourage submission of both original research and review articles that have immediate or promissory clinical applications. Topics of special interest include: 1) functional MR and CT of the brain and body; 2) advanced/innovative MRI techniques (diffusion, perfusion, rapid scanning); and 3) advanced/innovative CT techniques (perfusion, multi-energy, dose-reduction, and processing).
