We sought to determine the utility of a new metric, pant
leg volume, derived from the sum of the pulmonary trunk
and proximal portions of the right and left pulmonary
arteries for the non invasive determination of pulmonary
artery hypertension. We found that the non indexed
measurements of pant leg volume had the most significant
t test value for the determination of elevated pulmonary
arterial pressures.
