- For both CT angiography (CTA) and MR angiography (MRA) interpretation of the source data at a workstation is essential.
- CTA is particularly useful for assessment of aneurysm morphology.
- Accurate assessment of stenoses may be impossible in CTA images due to the presence of adjacent calcification.
- Stepping table gadolinium contrast enhanced MRA is the primary technique for peripheral vessels.
- Optimal MRI of the tibial arteries may require dedicated stations using separate contrast injections.
