3D black blood VISTA vessel wall cardiovascular magnetic resonance of the thoracic aorta wall in young, healthy adults: reproducibility and implications for efficacy trial sample sizes: a cross-sectional study

Table 1 Baseline characteristics of participants (n = 20)

	Non-contrast enhanced aortic wall characteristics	Contrast-enhanced aortic wall characteristics
	Mean (SD)^a	Mean (SD)^a
- Mean aortic lumen area (cm²)^a,b	2.52 (0.38)	2.63 (0.40)
- Mean aortic total vessel area (cm²)^a,b	3.54 (0.47)	3.66 (0.49)
- Mean aortic wall area (cm²)^a	1.02 (0.12)	1.05 (0.13)
- Mean aortic wall thickness (mm)^a	1.66 (0.15)	1.67 (0.15)
