Temporal muscle volume (TMV), measurable on routine head computed tomography (CT), may reflect skeletal muscle status.

TMV was measured on admission and follow-up CT scans during weeks 1\u20133. Absolute temporal muscle volume loss (ATMVL) and temporal muscle volume reduction rate (TMVRR) were calculated relative to baseline.
