To systematically review the techniques that address undersampling artifacts in accelerated quantitative magnetic resonance imaging (qMRI).
A literature search was conducted using the Embase, Medline, Web of Science Core Collection, Coherence Central Register of Controlled Trials, and Google Scholar databases for studies, published before July 2022 proposing reconstruction techniques for accelerated qMRI. Studies are reviewed according to inclusion criteria, and included studies are categorized based on the methodology used.
A total of 292 studies included in the review are categorized. A technical overview of each category is provided, and the categories are described in a unified mathematical framework. The distribution of the reviewed studies over time, application domain, and parameters of interest is illustrated.
An increasing trend in the number of articles that propose new techniques for accelerated qMRI reconstruction indicates the importance of acceleration in qMRI. The techniques are mostly validated for relaxometry parameters and brain scans. The categories of techniques are compared based on theoretical grounds, highlighting existing trends and potential gaps in the field.
系统地综述解决加速定量磁共振成像（qMRI）中欠采样伪影的技术。
使用 Embase、Medline、Web of Science 核心合集、Coherence Central 对照试验注册库和 Google Scholar 数据库，对截至 2022 年 7 月前提出用于加速 qMRI 重建技术的研究进行文献检索。根据纳入标准对研究进行审查，并根据所使用的方法对纳入的研究进行分类。
共纳入 292 项综述研究，并对每种类别进行技术概述，同时用统一的数学框架对类别进行描述。通过图示展示了综述研究在时间、应用领域和关注参数上的分布情况。
提出用于加速 qMRI 重建新技术的文章数量呈上升趋势，这表明加速在 qMRI 中的重要性。这些技术主要针对弛豫率参数和脑部扫描进行验证。从理论角度对技术类别进行比较，突出了该领域的现有趋势和潜在差距。
