- Roster: (Roster)
This Wiki is for collaborative creation of QIBA's Chronic Obstructive Pulmonary Disease (COPD) and Asthma Committee materials and ongoing activities.
Please note: As of July 2014, the group has been renamed as the QIBA Lung Density Biomarker Committee.
Mission: Reduce and characterize bias and variance across manufacturers, versions, and sites in support of quantitative CT lung densitometry and morphology.
Initial Objectives:
- 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.
