Description
Measuring the pulmonary artery on scans usually means widths or areas, but a full 3D volume might say more about pulmonary hypertension. The six authors studied 59 patients who had both right heart catheterization and CT pulmonary angiography. They split patients into 18 without and 41 with pulmonary hypertension, measured artery diameters by hand, and used 3D software to get cross-sectional areas and volumes of the central pulmonary arteries.
Every scan measure ran higher in the hypertension group and tracked the catheter pressures. For the main and right pulmonary arteries, 3D measures correlated more strongly than widths or areas. The right artery volume beat its width and area clearly in curve analysis, and decision curve analysis favored the 3D measures. The team also built simple equations that estimate catheter pressures from the main artery volume and width.
