Quantitative susceptibility mapping (QSM) is an MRI-based technique for iron quantification of targeted tissue. QSM provides information relevant to clinicians in a broad range of diagnostic contexts, including sickle cell disease, inflammatory/demyelinating processes, and neoplasms. However, major MRI vendors do not offer QSM post-processing in a form ready for general use. This work describes a vendor-agnostic approach for scaling QSM analysis from a research technique to a routine diagnostic test. We provide the details needed to seamlessly integrate hardware, software, and clinical systems to provide QSM processing for a busy clinical radiology workflow. This approach can be generalized to other advanced MRI acquisitions and analyses with proven diagnostic utility, yet without crucial MR vendor support.
定量磁化率成像(QSM)是一种基于磁共振成像(MRI)的技术,用于对目标组织进行铁定量分析。QSM在广泛的诊断环境中为临床医生提供相关信息,包括镰状细胞病、炎症/脱髓鞘过程和肿瘤。然而,主要的MRI设备供应商并未以可供普遍使用的形式提供QSM后处理功能。这项工作描述了一种与供应商无关的方法,用于将QSM分析从研究技术扩展为常规诊断测试。我们提供了无缝集成硬件、软件和临床系统所需的详细信息,以便为繁忙的临床放射学工作流程提供QSM处理。这种方法可以推广到其他具有已证实诊断效用的先进MRI采集和分析中,而无需关键的MR设备供应商支持。
