We investigated whether total psoas muscle area (TPMA) was representative of the volume (TPMV). Secondly, we assessed there a relationship between two commonly used single slice measurements sarcopenia, TPMA and abdominal (TAMA).Pre-operative CT imaging 110 patients undergoing elective endovascular aneurysm repair were analyzed by trained independent observers. measured at individual vertebral levels second lumbar vertebrae sacrum. TPMV also estimated TAMA third (L3). Observer differences using Bland-Altman plots. Associations different measures linear regression Pearson's correlation.We found to be L2 The strongest association seen L3 [adjusted coefficient 16.7, 95% confidence interval (12.1 21.4), p < 0.001]. There no -0.7, (-4.1 2.8), = 0.710].We demonstrate that sacrum are TPMV, with greatest vertebrae. TAMA.We measurement is volume, contrary previous criticism. Future sarcopenia studies can continue measure which TPMV.
