Psoas Muscle Area Measured with Computed Tomography at Admission to Intensive Care Unit: Prediction of In-Hospital Mortality in Patients with Pulmonary Embolism

Figure 2

65-year-old woman with pulmonary embolism. The value of psoas muscle area was obtained by dividing the sum of the right and left psoas muscle areas at the level of L3 vertebrae into body surface areas using single axial CT scan images. He had higher PESI scores, lower arterial oxygen saturation, and higher respiratory rate in-hospital mortality.
