For
lung imaging, depiction of pulmonary artery (PA) and vein (PV) can be done
using ASL based technique. However, visualization of PV using conventional
ASL approach is challenging because tagged blood in the pulmonary artery
requires several seconds to reach the vein. In this work we evaluated the
possibility of simultaneous visualization of PA and PV using ASL based
technique at multiple inversion times (TI). For PA, high scores were observed
at TI=800ms and 1100ms respectively; For PV, highest score was observed at
TI=300ms. Expected clinical application is imaging of patients with pulmonary
infarction.
