Fig. 1From: Skeletal muscle quality as assessed by CT-derived skeletal muscle density is associated with 6-month mortality in mechanically ventilated critically ill patientsExample of CT scan analysis. This image shows CT scans at the level of lumbar vertebra 3 of two patients both un-analysed (upper row) and analysed (lower row). The analysed images show muscle tissue (red) and intermuscular adipose tissue (IMAT, green). The patient on the left has more muscle (165 vs. 120Â cm2), less IMAT (10 vs. 19.5Â cm2), and higher mean skeletal muscle density (42 vs. 18 Hounsfield Units) than the patient on the rightBack to article page
