CT-based analysis of ESM mass
CT-based radiological measurements were an essential part of this study.
As in a previous study, the cross-sectional areas of bilateral ESM were
performed on a single axial chest CT image at the level of the lower
margin of the 12th thoracic vertebrae 2-5. In this
study, we used the ESM index as per the formula = ESM area/body mass
index (BMI), which was analyzed for the quantification of ESM areas,
according to the patient’s physics. Furthermore, Hounsfield units (HU)
of the ESM were determined to assess the density of the ESM.
