Skeletal paraspinal muscle changes in a patient with cancer cachexia: axial abdominal MRI scan of a 74 year-old patient with squamous cell carcinoma of the esophagus at baseline (left image) and follow-up after 335 days (right image). Relative muscle volume change was − 19.9% for the erector spinae and − 26.3% for the psoas muscle. Relative change of contractile tissue volume was − 19.4% in erector spinae muscle and 25.3% in psoas muscle. Relative change in fat volume was − 21.2% in erector spinae muscle and 27.7% in psoas muscle. Absolute PDFF (%) difference was 0.5 in erector spinae muscle and 1.3 in the psoas muscle. BMI decreased from 24.1 to 21.1 kg/m2. BMI body mass index, PDFF proton density fat fraction
