Analysis of the possibility of obtaining super-paramagnetic powders based on Ferro oxides as precursor by MR contrast material synthesis

摘要

Contrast materials have very great role in many medical areas. Considering modern medical diagnostic techniques and the significance of the solution to the therapy (or surgery) tasks, the questions on precise medical images of high resolution are very important. The high resolution (especially if the image serves further for the numerical processing and analysis is certainly of significances as well as the material for recording or other assisting tasks. The contrasts material for the processes of magnetic resonance (or NMR) and analysis of their performances in the form of initial powder material with super paramagnetic performances are presented in this paper.
