Three- and Four-Dimensional Imaging in Acute Aortic Syndrome

Computed tomography angiography (CTA) is an established imaging technique providing highly accurate clinical information of the thoracic aorta. The widespread availability and round-the-clock accessibility of modern-day multidetector-row CT (MDCT) technology in virtually all emergency rooms, a proven track record of CTA with sensitivity and specificity approaching 100% for the detection of acute thoracic aortic disease and the ability to detect other potentially clinically important pathology has led to the replacement of conventional diagnostic angiography by CTA [1]. The development of CTA with ECG gating provides additional advantages by eliminating cardiac pulsation and motion artefacts, further extending the clinical applicability of CTA to include aortic-root imaging. ECG gating, when performed retrospectively over the entire cardiac cycle, allows cardiac phase-resolved (time-resolved) cine imaging and visualisation, adding yet another dimension (4D) to this robust technique.
