MRI contrast agents are an important means to improve MRI imaging. This article mainly studies the properties of EDTA, DTPA and amino salicylic acid metal chelates as MRI contrast agents.Firstly, the structures and properties of EDTA, DTPA and amino salicylic acid metal chelates were introduced. Then, the application of these compounds in MRI imaging was studied through experiments. It was found that these compounds can effectively improve the contrast of MRI imaging, and have good biocompatibility and degradability, without obvious toxic side effects on human and animal.精品文档---下载后可任意编辑Next, this article will focus on the properties of these compounds, including contrast, contrast agent metabolism rate, safety of contrast agents on human and animals, and so on. Finally, we will further explore the development prospects and application value of these compounds.Keywords: Magnetic resonance imaging; MRI contrast agents; EDTA; DTPA; amino salicylic acid metal chelates; contrast; safety.
