Protocol selection guidelines:
- For known/suspected ascending aortic aneurysm or dissection: Use gated CTA (prospective is much lower dose and preferred)
- For known/suspected descending aortic aneurysm or dissection: Use non-gated CTA
- For chest pain, r/o dissection/aneurysm: Use non-gated CTA
Contrast guidelines:
- Acute Aorta (dissection, intramural hematoma, penetrating atherosclerotic ulcer): protocol as BOTH noncon and with contrast
- Repaired aneurysm w/ endovascular stent:
- Protocol as BOTH noncon and with contrast and put 2 min delay in comments
- FYI only - UWHC does some of these as non only, but that requires immediate access to 3D volume calculations which we don't have available at 1SP or Meriter
- Repaired aneurysm w/ open surgical repair: protocol as BOTH noncon and with contrast
- Known unrepaired aneurysm f/u: single phase - noncon only is fine, or CTA arterial phase is acceptable instead
