From: Imaging of the aortic root on high-pitch non-gated and ECG-gated CT: awareness is the key!
A 41-year-old-man with incidentally detected sinus of Valsalva aneurysm. Non-contrast chest CT (a) obtained as a work-up for fever showed an incidental dilatation (white arrow) of the aortic root (CT was done with high pitch, enabling the anatomic evaluation of aortic root despite the lack of ECG gating). Follow-up contrast-enhanced-gated CTA images (b and c) showing an incidental aneurysm of the noncoronary sinus of Valsalva (black arrow)
