Poster Information
Abstract: Hand grip strength (HGS) and fat free mass index (FFMI) are important indicators of skeletal muscle mass and therefore prognosis in patients with respiratory diseases including cystic fibrosis (CF)1,2. CT’s have become gold standard in assessing lean body mass (LBM) in cachexia in other diseases including cancer. It provides accurate information regarding muscle mass and adipose tissue allowing for singular or longitudinal assessments over time2. This information can be used to improve our understanding of LBM and its correlation with lung function and patient outcome. We propose that calculating muscle volume and density on CT imaging would correlate strongly with FFMI and HGS. This could provide important information to centres where HGS and FFMI testing is lacking and provide prognostic value in CF patients.
Summary: Aims
Identifying a correlation between muscle volume and density on CT images with;
Lean Body Mass (LBM)
Hand Grip Strength (HGS)
Fat Free Mass Index (FFMI)
Lung Function
