ROC curve comparisons among one-, two- and three-dimensional parameters of the main (4A), right (4B), and left (4C) pulmonary artery in predicting PH. The comparison of the ROC curves in predicting PH among the volumes (the green lines), cross-sectional areas (the blue lines), and the diameters (the red lines) of the MPA (4A), RPA (4B), and LPA (4C). (Abbreviations: ROC, receiver operating characteristic; AUC, area under the curve; DMPA, diameter of main pulmonary artery; AMPA, cross-sectional area of main pulmonary artery; VMPA, volume of main pulmonary artery; DRPA, diameter of right pulmonary artery; ARPA, cross-sectional area of right pulmonary artery; VRPA, volume of right pulmonary artery; DLPA, diameter of left pulmonary artery; ALPA, cross-sectional area of left pulmonary artery; VLPA, volume of left pulmonary artery)
