Impact of CT injector technology and contrast media viscosity on vascular enhancement: Evaluation in a circulation phantom.

CONCLUSIONS: The tested piston-based injection systems combined with low viscosity contrast media provide higher achievable IDRs and higher peak vascular enhancement than the tested peristaltic-based injectors. With equivalent IDRs, Centargo provides higher peak vascular enhancement due to improved bolus shape. ADVANCES IN KNOWLEDGE: This paper introduces a new parameter to compare expected performance among contrast media: the concentration/viscosity ratio. Additionally, it demonstrates previously unexplored impacts of bolus shape on vascular enhancement. PMID: 32017607 [PubMed - as supplied by publisher]
