Clinical evaluation of a novel multibolus contrast agent injection protocol for thoraco-abdominal CT angiography: Assessment of homogeneity of arterial contrast enhancement.

•A multibolus injection for long-range CTA was established in patients.•A multibolus injection provides a plateau of homogenous arterial enhancement.•Arterial attenuation is more homogenous than in a single-bolus injection.•In aortic dissections attenuation differences between lumina are reduced.
