Fig. 5From: Diagnostic value of 3D volume measurement of central pulmonary artery based on CTPA images in the pulmonary hypertensionDecision curve analysis of the CTPA parameters for the MPA (A) and RPA (B) in the estimation of PH. In the Figure, the x-axis is the threshold probability, and the y-axis measures the net benefit. The red line represents the one-dimensional, the green line represents the two-dimensional, and the blue line represents the three-dimensional parameters of the MPA and RPA. (Abbreviations: CTPA, computed tomography pulmonary angiography; PH, pulmonary hypertension; 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)Back to article page
