Comparison of Ultrasound‐Derived Muscle Thickness With Computed Tomography Muscle Cross‐Sectional Area on Admission to the Intensive Care Unit: A Pilot Cross‐Sectional Study

INTRODUCTION: The development of bedside methods to assess muscularity is an essential critical care nutrition research priority. We aimed to compare ultrasound-derived muscle thickness at 5 landmarks with computed tomography (CT) muscle area at intensive care unit (ICU) admission. Secondary aims were to (1) combine muscle thicknesses and baseline covariates to evaluate correlation with CT muscle area and (2) assess the ability of the …
