The early arterial phase, also known as the early systemic arterial phase, is a contrast-enhanced CT or MRI series, in which the contrast (e.g. iodinated or gadolinium) is still in the arteries and has not reached the organs and other soft tissues.

Technique
The acquisition time depends on the intravenous device (central or peripheral), the concentration of the contrast medium, and the injection rate.
time from injection through an upper extremity vein: 15-25 seconds 1
time from bolus tracking: immediately
Clinical use
The early arterial phase offers optimal vessel demarcation and allows the detection of vascular pathology:
