Motion characterization of aortic wall and intimal flap by ECG-gated CT in patients with chronic B-dissection
Abstract Rationale and objectives To evaluate whether dynamic computed tomography (CT)-imaging can provide functional vessel information in patients with chronic aortic dissection type Stanford-B (ADB). Materials and methods In 32 patients, ECG-gated CT-angiography images were obtained. Cross-sectio...

| description | Abstract Rationale and objectives To evaluate whether dynamic computed tomography (CT)-imaging can provide functional vessel information in patients with chronic aortic dissection type Stanford-B (ADB). Materials and methods In 32 patients, ECG-gated CT-angiography images were obtained. Cross-sectional area change and wall distensibility were investigated by semiautomatic vessel area segmentation at the end of aortic arch. Significance of distensibility differences was tested with regard to the aortic diameter, and the oscillation of the intimal flap was analyzed. Results The aorta could be segmented successfully in all patients. These were separated into three subgroups: (A) 6 patients with an aortic diameter |

Significance of distensibility differences was tested with regard to the aortic diameter, and the oscillation of the intimal flap was analyzed. Results The aorta could be segmented successfully in all patients. These were separated into three subgroups: (A) 6 patients with an aortic diameter <4 cm and without a visible intimal flap, (B) 9 patients with an aortic diameter <4 cm, and (C) 17 individuals with an aortic diameter ≥4 cm; (B) and (C) having a visible intimal flap. Differences in distensibility between the subgroups were not significant. Overall mean distensibility was Dtot = (1.3 ± 0.6) × 10−5 Pa−1 . Analysis of intimal flap oscillation showed a pulsatile short axis diameter decrease of the true lumen of up to 29%. Conclusion Dynamic, ECG-gated CT-angiography can demonstrate pulsatile changes in aortic area and a highly variable motion of the intimal flap.
