Gold nanoparticles spectral CT imaging and limit of detectability in a new materials contrast-detail phantom

Nanomaterials offer a significant potential in the medical field for imaging and treatment of tumor and cancer cells [1]. Recent investigations have explored the potential of high atomic number (Z) nanoparticles such as gold and bismuth, as contrast agents for computed tomography (CT) [2,3]. Among these high-Z nanoparticles, gold nanoparticles (AuNPs) stand out due to their superior biocompatibility, prolonged blood circulation durations, and higher CT contrast enhancement compared to other nanoparticles [4 –6].
