Material and Method: TIA synthesis was obtained using ultrasonic sound waves, and nanocrystals were obtained by nanoprecipitation method from this synthesized substance. NMR and Q-TOF analyzes were performed for the characterization of TIA. For the characterization of nanocrystals, optical microscope, zeta potential, particle size, and distribution, SEM and FT-IR analyzes were performed. The obtained nanosuspension was compared by the CT technique with iopromide and iohexol in terms of radiocontrast properties. Result and Discussion: The size of the prepared nanoparticles based on the synthesized pure TIA was found to be ~699 nm and zeta potentials as ~ (-)16 mW. Morphologies were determined by SEM and optical microscope images. It was determined by FT-IR that the obtained nanocrystals do not exhibit a different structure than the synthesized TIA. On CT images, TIA nanosuspension was found to exhibit ~ 40% more contrast than the same amount of iopromide and iohexol. As a result, it has been shown that nanocrystals can perform similar imaging by using less radiocontrast materials with their unique properties. In this way, it is likely to cause fewer side effects and/or toxic effects due to the lower dosage. In the light of these successful results, it is planned to detail this study with clinical trials in the future.
