Bismuth Sulfide Nanoparticles as a Complement to Traditional Iodinated Contrast Agents at Various X-Ray Computed Tomography Tube Potentials
Author(s): Merfat Algethami, Anton Blencowe, Bryce Feltis and Moshi Geso
Background: Investigation of the contrast enhancement effects on the CT images of the conventional iodinated contrast media (CM) or bismuth sulfide nanoparticles (Bi2S3 NPs) with increasing x-ray tube potentials.
Materials and methods: A phantom was filled with iodinated CM or Bi2S3 NP solutions at concentrations ranging from 0 to 65 mM and the phantom was scanned with a CT scanner using tube potentials of 80, 100, 120 and 140 kVp at a fixed current of 200 mA. The CT contrast enhancement and contrast-to-noise ratios (CNR) of all scanned images were calculated.
Results: This study demonstrated that greater image contrast was observed with Bi2S3 NPs compared to the iodinated CM at all concentrations and energies (80-140 kV... view more»
