does NOT break down into ions after injection
Less intense burning sensation after injection and fewer reactions accociated
Iodine concentrations for angiography
30-35%
direct stick
directly sticking the artery with a needle and injecting through the stick
cut-down
surgically exposing a vessel and inserting a catheter

1. insert needle THROUGH the desired artery (usually femoral)
2. pull needle back into the lumen of the artery and withdraw the stylette
3. thread the guidewire through the canula
4. The cannula is removed after the guidewire is in place
