PREPARATION OF NANO SIZE IRON OXIDE FOR MRI CONTRAST AGENT BY ULTRASONIC AND MANUFATURING METHOD THEREOF AND MANUFATURING METHOD OF MRI CONTRAST AGENT USING IRON OXIDE NANO PARTICLE AND MRI CONTRAST AGENT THEREOF
PREPARATION OF NANO SIZE IRON OXIDE FOR MRI CONTRAST AGENT BY ULTRASONIC AND MANUFATURING METHOD THEREOF AND MANUFATURING METHOD OF MRI CONTRAST AGENT USING IRON OXIDE NANO PARTICLE AND MRI CONTRAST AGENT THEREOF
The present invention relates to an iron oxide nanopowder used in MRI contrast agent prepared using ultrasonic waves, a method for preparing the same, and a method for preparing the MRI contrast agent using the same, and an MRI contrast agent, the purpose of which is to use an inexpensive iron salt compound, The present invention provides an iron oxide-polysaccharide MRI contrast agent and a method for manufacturing the same, and a method for producing iron oxide nanopowders which can be produced economically and economically.;The constitution of the present invention is to adjust the pH of the mixed solution of ferrous salts and ferric salts in distilled water to 9-12, and then irradiate the mixed solution with ultrasonic waves to provide excellent crystallinity and uniform particle size. Preparing an iron oxide powder; Washing the iron oxide powder prepared in the step to be 6-7 having a neutral pH as deionized tertiary distilled water; 2wt%-5wt% of washed powder The technical features of the iron oxide nanopowder and MRI contrast agent, and the iron oxide nanopowder and MRI contrast agent prepared therefrom comprising the step of dispersing by using ultrasonic waves in a polysaccharide solution.;Iron oxide nano powder, SPIO, USPIO, MRI contrast agent, polysaccharide, oligosaccharide, chitosan, ultrasonic
