ECG gating CTs for aortic dissection/aneurysm rule out
- Increasing evidence supports the use of ECG gating when performing CTs to rule out aortic pathology-dissection and aneurysm.
- The most common artifact on CT is a "psuedo-dissection" flap caused by excessive motion at the aortic root. Administering beta blockers before CT will limit this motion and decrease the chance of this false positive.
