Regional analysis of lung ventilation is facilitated
through multi-breath Hyperpolarized gas (HP) MRI, a
technique that quantifies the Specific Ventilation (SV)
in parenchyma. This work presents the first preliminary
short- and long-term variability of SV-MRI, and compares
the imaging variability to that of pulmonary function
tests (PFT).
