Abstract

The availability of magnetic nanoparticles (MNPs) with medical approval for human intervention is fundamental to the clinical translation of magnetic particle imaging (MPI). In this work, we thoroughly evaluate and compare the magnetic properties of an magnetic resonance imaging (MRI) approved tracer to validate its performance for MPI in future human trials.We analyze whether the recently approved MRI tracer Resotran is suitable for MPI. In addition, we compare Resotran with the previously approved and extensively studied tracer Resovist, with Ferrotran, which is currently in a clinical phase III study, and with the tailored MPI tracer Perimag.Initial magnetic particle spectroscopy (MPS) measurements indicate that Resotran exhibits performance characteristics akin to Resovist, but below Perimag. We provide data on four different tracers using dynamic light scattering, transmission electron microscopy, vibrating sample magnetometry measurements, MPS to derive hysteresis, point spread functions, and a serial dilution, as well as system matrix based MPI measurements on a preclinical scanner (Bruker 25/20 FF), including reconstructed images.Numerous approved MNPs used as tracers in MRI lack the necessary magnetic properties essential for robust signal generation in MPI. The process of obtaining medical approval for dedicated MPI tracers optimized for signal performance is an arduous and costly endeavor, often only justifiable for companies with a well-defined clinical business case. Resotran is an approved tracer that has become available in Europe for MRI. In this work, we study the eligibility of Resotran for MPI in an effort to pave the way for human MPI trials.

摘要

获得医学批准可用于人体干预的磁性纳米颗粒(MNP)是磁性粒子成像(MPI)临床转化的基础。在这项工作中,我们全面评估并比较了一种经磁共振成像(MRI)批准的示踪剂的磁性能,以验证其在未来人体试验中用于MPI的性能。我们分析了最近批准的MRI示踪剂Resotran是否适用于MPI。此外,我们将Resotran与先前批准并经过广泛研究的示踪剂Resovist、与目前处于临床III期研究的Ferrotran以及定制的MPI示踪剂Perimag进行了比较。初始磁颗粒光谱(MPS)测量表明,Resotran表现出与Resovist类似的性能特征,但低于Perimag。我们使用动态光散射、透射电子显微镜、振动样品磁强计测量、MPS来推导磁滞、点扩散函数和系列稀释,以及在临床前扫描仪(布鲁克25/20 FF)上基于系统矩阵的MPI测量(包括重建图像),提供了四种不同示踪剂的数据。许多在MRI中用作示踪剂的已批准MNP缺乏在MPI中产生强大信号所必需的磁性能。为针对信号性能进行优化的专用MPI示踪剂获得医学批准的过程是一项艰巨且成本高昂的工作,通常只有对于具有明确临床商业案例的公司才是合理的。Resotran是一种已在欧洲获批用于MRI的示踪剂。在这项工作中,我们研究Resotran用于MPI的适用性,以期为人体MPI试验铺平道路。
