Coronary CT angiography using low concentrated contrast media injected with high flow rates: Feasible in clinical practice

Highlights • Usage of low iodine concentrated CM and injection with high flow rates is feasible in CCTA. • High flow rates were injected without complications or differences in peak pressure. • No significant differences in subjective and objective image quality were found between groups. • Injectio...

Zusammenfassung:	Highlights • Usage of low iodine concentrated CM and injection with high flow rates is feasible in CCTA. • High flow rates were injected without complications or differences in peak pressure. • No significant differences in subjective and objective image quality were found between groups. • Injection protocols with high flow rates and low concentrated CM should not be considered a drawback in clinical practice.
