Lung Density Biomarker Ctte
- Co-chairs: Sean Fain, PhD; Charles Hatt, PhD; David Lynch, MD
- RSNA Staff Support: Julie Lisiecki
Scope: Quantitative CT lung densitometry and morphology for COPD and related diseases.
- Characterize the precision and accuracy of phenotyping and progression measurements in emphysema and asthma.
- This is an essential effort to classify phenotype and assess longitudinal changes as medically meaningful surrogates for health status.
- Compare the sensitivity of CT measurements to spirometry and other accepted measures.
- This will be necessary in order to determine if Progressive Disease can be detected significantly sooner with quantitative imaging techniques than with currently accepted methods.
