Assessment of the skeletal and the psoas muscle index at level of the third vertebra (L3SMI and L3PMI). L3SMI was assessed by measuring m. psoas, m. erector spinae, m. quadratus lumborum, m. rectus abdominis, m. transversus abdominis, m. obliquus abdominis internus, and m. obliquus abdominis externus in a single slice at the level of the third vertebra using the 3D Slicer and normalizing it to the patient’s height. For L3PMI only the left m. psoas was measured and normalized to the patient’s body height. Examples for high (A,C) and low (B,D) L3PMI and L3SMI values.
