The demand for measurements of fat quantities is driven by the rising prevalence of sarcopenia and sarcopenic obesity (SO). In order to reduce the time and the cost of image processing, several studies have estimated the subcutaneous fat (SF) and visceral fat (VF) volume from a single slice. However, the population of studies may not have necessarily included patients with either sarcopenia or SO. This study aims to determine the correlation between the cross-sectional areas in a single slice at different vertebra levels and the volumes of SF and VF in the abdomen for sarcopenic and SO populations using MRI.
