(A) and (C) showing non-ECG-gated prereferral CTA suggesting aortic dissection in patient 1; (B) and (D) showing postoperative scan acquired in gated high-pitch mode and with subsecond level acquisition time.. Abbreviations: CTA, computed tomography angiography; ECG, electrocardiography.

Non-ECG-gated CTA gave rise to a diagnosis of circumferential AAD extending from the aortic root throughout the transverse arch (Figure 1).

(A) and (C) showing non-ECG-gated prereferral CTA suggesting circumferential dissection of the ascending aorta in patient 2; (B) and (D) showing gated repeat CTA without misleading artifacts.. Abbreviations: CTA, computed tomography angiography; ECG, electrocardiography.

Non-ECG-gated CTA showed structures that were interpreted as a circumferential dissection of the aortic root and ascending aorta (Figure 2), which resulted in immediate referral of the patient for emergent surgery.

(A) Non-ECG-gated prereferral CTA suggessting dissection of the ascending and descending aorta and (B) ECG-gated repeat CTA confirming only type B dissection in patient 4. (C) Suspicious structures at the level of the proximal ascending aorta in the non-ECG-gated prereferral scan of patient 3 that are absent in the ECG-gated repeat scan shown in (D).. Abbreviations: CTA, computed tomography angiography; ECG, electrocardiography.

Prereferral non-ECG-gated CTA performed at the community hospital showed a severely diseased aorta with dissection extending from the ascending aorta to the infrarenal aorta (Figure 3).

(A) and (C) showing non-ECG-gated axial and coronal CTA images suggesting dissection at the level of the aortic root in patient 5. (B) and (D) showing the ECG-gated CT scan of the same patient subsequently performed on a 256-MSCT device that showed no aortic dissection.. Abbreviations: CTA, computed tomography angiography; ECG, electrocardiography; MSCT, multislice CT.
