Axillary and Brachial Angiogram

These are two images of the axillary and brachial arteries. The image on the left is taken earlier, and that on the right, later. The contrast was injected via a catheter which was placed into the subclavian artery/axillary artery junction. Notice that on the later image, the axillary artery isn't as visible, as unopacified blood flows into the axillary artery and mixes with and dilutes the x-ray dye.
