Aims: The control of healthcare-associated infections (HCAIs) is a significant concern in the field of radiology due to multiple contact-transmitted pathogens on imaging devices. The antimicrobial effects of silver nanoparticles (AgNPs) in preventing HCAIs and their effects on imaging quality were evaluated. Methods: The antimicrobial effects of AgNPs were tested on prevalent contact-transmitted pathogens present in radiology examination rooms, including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococci (VRE), Pseudomonas aeruginosa, and Acinetobacter baumannii. Furthermore, we investigated the effects of AgNPs on X-ray image quality using humanoid head and hand phantom. Results: AgNPs did not affect the quality of X-ray images. They had antimicrobial effects against Gram-positive Bacillus, including MRSA, VRE, and Gram-negative Bacillus, including P. aeruginosa and A. baumannii. Conclusion: AgNPs are considered effective in controlling HCAIs in radiology through sterilization by coating shooting devices and accessories where physical contact between patients and healthcare professionals is frequent.
