CT low attenuation area quantification versus visual scoring for early pulmonary emphysema detection in lung cancer screening.
OBJECTIVES To compare low-attenuation analysis (LAA) with visual scoring and explore their application in the detection of emphysema in low-dose CT (LDCT) scans. METHODS A random cohort of 352 CT examinations from health-check participants was selected from a lung cancer screening(LCS) dataset. Scans were evaluated f...
