123
The dynamics of the contrast enhancement is deter-
mined by:
• Patient cardiac output
•Injection rate
• Total volume of contrast medium injected
• Concentration of the contrast medium
• Type of injection – uni-phasic or bi-phasic
• Patient pathology
Aortic time-enhancement curves after i.v. contrast
injection (computer simulation*).
All curves are based on the same patient parameters
(male, 60-year-old, 75 kg).
