The muscle area was measured using a cross-sectional CT image at the level of the 12th thoracic vertebra. (A) shows the cross-sectional CT image at the level of the 12th thoracic vertebra for a 64-year-old man patient. The calculated SMI was 44.0 cm2/m2, which exceeds the cut-off value for men, and the patient was diagnosed as non-sarcopenic. (B) shows the cross-sectional CT image at the level of the 12th thoracic vertebra for a 71-year-old woman patient. The calculated SMI was 27.3 cm2/m2, which is below the cut-off value for women, and the patient was diagnosed with sarcopenia. CT computed tomography; SMI skeletal muscle index.
