<br/><br/> This work and research is first time nationally and internationally introduced to be a novel research in healthy MRI contrast agents. A two water phantoms used. Each one is constructed of biodegradable latex rubber balloons filled with 450 ml. The resulted image for both magnetized and non-magnetized water phantoms are quantitatively processed by MATLAB Genetic Algorithms (Gas), These images show that T1 is increased to 1.513 s (225%) in magnetized phantom instead of 0.672 s in non magnetized one and S/N increased from 156.3 to 337.5-216%
