We investigated whether lung ultrashort echo-time (UTE)
MRI could generate quantitative imaging biomarkers for
patients diagnosed with chronic obstructive pulmonary
disease (COPD). COPD patients and control subjects were
imaged via UTE MRI; these images were compared to chest
CTs, both qualitatively and quantitatively. UTE MRI
signal intensity was lower in the COPD group (p<0.001)
and emphysema index (EI) was higher (p<0.006). EI of MRI
correlated well with EI calculated via CT (R2=0.82).
This study demonstrates that UTE MRI can be employed to
quantify tissue destruction in emphysema patients, and
can potentially assess COPD extent and severity.
