“…Using gated multislice CTA, Murayama et al investigated pulsatility in AD by quantifying true lumen area changes in the axial CTA images and concluded that in AD, pulsating-type is more common if in the acute phase from onset or if the entry is not located at the distal-portion of descending-thoracic-aorta with retrograde flow in false lumen thrombosis. 23 However, the effective estimated radiation dose of 128 slice triple rule-out gated CTA for excluding AD, pulmonary embolism, and acute coronary artery syndrome was recently reported to ranged from 7.4-13.4 mSv and from 10.1-17.5 mSv for men and women, respectively, for retrospective triggered acquisitions and from 5.9 mSv and 8.2 mSv for men and women, respectively, for prospectively triggered CTAs. 24 While these doses are quite acceptable for single examinations, it may be less suitable for longitudinal studies with many repeated examinations.…”

“…Retrospective ECG-gated CTA allows the phase-resolved cine imaging and visualization. The “four dimension” images can assess the dynamics of the intimal flap movement within a cardiac cycle [9], [10], [11]. In addition, the artifacts of the ascending aorta caused by the cardiac pulsation can be eliminated by this technique.…”

“…ECG-gated imaging is, however, mandatory for adequate coronary artery CT and might be advantageous for the imaging of the aorta in order to reduce pulsation artefacts [17,18]. A dedicated CT protocol for suspected pulmonary embolism requires high attenuation in the right heart chambers and the pulmonary arteries.…”
