Contrast Saline Mixture DualFlow Injection Protocols for Low-Kilovolt Computed Tomography Angiography

Objective The aim of this study was to evaluate a contrast media (CM)–saline mixture administration with DualFlow (DF) to adapt injection protocols to low-kilovolt (kV) computed tomography angiography (CTA). Materials and Methods In both a circulation phantom and animal model (5 Goettingen minipigs), 3 injection protocols were compared in dynamic thoracic CTA: ( a ) DF injection protocol at 80 kV with a iodine delivery rate (IDR) of 0.9 gI/s, a...
