Pitfalls in Suspected Acute Aortic Syndrome: Impact of Appropriate and If Required Repeated Imaging

Figure 1

Double-oblique (a) and axial (b) reconstructions (spatial resolution 3 × 0.5 × 0.25 mm) of the initial inadequate ECG-gated contrast-enhanced CT resulting from repeated premature ventricular contractions at the time of image acquisition. Consider the small contrast signal in the left anterior quadrant of the ascending aorta, misdiagnosed as a pseudointimal flap/motion artifact.
