Distribution of the measurements of the mean peak clockwise and counter-clockwise RV in mL and % (based on the flow volumes in the corresponding vessel section) and the time of the occurrence of peak RBV in ms and % (based on the length of the cardiac cycle) in the ascending aorta, the aortic arch and the thoracic descending aorta. Comparisons between percentages of clockwise and counterclockwise flow volumes. †, comparison between clockwise and counter-clockwise/patients and volunteers. RBV, rotating blood volume; SD, standard deviation; L-R, left coronary-right coronary; L-N, left coronary-non-coronary; R-N, right coronary-non-coronary; RV, rotational volume.
