磁共振成像(MRI)是一种非侵入性成像技术,能够获得高分辨率的人体解剖图像。MRI的主要缺点是对比剂敏感性低,无法区分健康组织和病变组织,这使得早期发现具有挑战性。为了解决这一技术障碍,顺磁造影剂已经被开发出来,以增加纵向弛豫度(R1),从而导致信噪比的增加。本文重点介绍了纳米粒子的设计和制造方法和原理,这些方法和原理使纳米粒子能够提供具有增强离子弛豫性能的造影剂。不同的工程策略和纳米颗粒平台将在可制造性、生物兼容性以及它们在临床磁共振成像中产生影响的总体潜力方面进行比较。
Magnetic resonance imaging (MRI) is a noninvasive imaging technique capable of obtaining high-resolution anatomical images of the body. Major drawbacks of MRI are the low contrast agent sensitivity and inability to distinguish healthy tissue from diseased tissue, making early detection challenging. To address this technological hurdle, paramagnetic contrast agents have been developed to increase the longitudinal relaxivity (R1), leading to an increased signal-to-noise ratio. This review focuses on methods and principles that enabled the design and engineering of nanoparticles to deliver contrast agents with enhanced ionic relaxivities. Different engineering strategies and nanoparticle platforms will be compared in terms of their manufacturability, biocompatibility properties, and their overall potential to make an impact in clinical MR imaging.
