Download scientific diagram | Explanation of terms. The contrast medium aortic arrival time is the time from injection until the increased CT value exceeds 5 HU. The aortic enhancement rate is the slope of the linear equation of increased CT value ranging from 5 HU (contrast medium aortic arrival time) to the average trigger threshold in the clinical study (in HU/s). The rise time is the elapsed time to peak aortic enhancement from the aortic arrival time of the contrast medium  from publication: Optimizing scan timing of hepatic arterial phase by physiologic pharmacokinetic analysis in bolus-tracking technique by multi-detector row computed tomography | Our aim in this study was to determine an optimal delay time of hepatic arterial phase (HAP) imaging of hypervascular hepatocellular carcinomas (HCCs) in dynamic contrast-enhanced MDCT (DCE-CT) by use of the bolus-tracking method.
