概括

雷索特兰 (Resotran) 是一种核磁共振扫描 (MRI) 认可的追踪剂,显示了磁粒子成像 (MPI) 人体试验的潜力. 虽然它的性能可以与Resovist相提并论,但它比专用MPI追踪器 (如Perimag.com) 效率要低.

科学领域:

生物医学工程生物医学工程
纳米技术纳米技术
医疗成像医学成像

背景情况:

磁粒子成像 (MPI) 的临床翻译需要经过医学批准的磁纳米粒子 (MNP).
现有的核磁共振 (MRI) 认可的跟踪器可能没有最佳的磁性特性来产生强大的MPI信号.

研究的目的:

为了评估Resotran的适用性,最近通过MRI批准的标记剂,用于MPI应用.
为了比较Resotran的磁性与MPI的其他已知标记剂 (Resovist,Ferrotran,Perimag) 的磁性特性.

主要方法:

磁粒子光谱 (MPS) 用于性能分析.
动态光散射,传输电子显微镜,振动样品磁力学.
在临床前扫描仪 (Bruker 25/20 FF) 上进行MPI测量,并进行图像重建.

主要成果:

雷索特兰的MPS性能与Resovist相似,但低于Perimag.
获得了四种标记物的综合数据,包括歇斯底里,点传播函数和连续稀释.
临床前的MPI扫描显示了Resotran的成像能力.

结论:

作为未来人类MPI试验的可访问的追踪剂,Resotran显示出希望.
尽管它与专用MPI追踪器不匹配,但它的可用性可能会加速临床转化.
需要进一步验证才能完全确定Resotran在MPI中的作用.

关键词:

在 DLS 中,您可以使用 DLS.在MPI中,MPI是MPI.对于MPS来说,这是一个很好的选择.一个复苏主义者.这就是TEMEM.这是VSMVSM.铁碳玻璃管是什么意思

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Positron Emission Tomography

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...
