Reliability, costs, and radiation dose of dual-energy X-ray absorptiometry in diagnosis of radiologic sarcopenia in surgically menopausal women

ConclusionsDXA has lower costs and a lower radiation dose, with low inter- and intra-observer variability, compared to CT and MRI for assessing lower limb muscle mass.Trial registrationNetherlands Trial Register; NL8068.Critical relevance statementDXA is a good alternative for CT and MRI in assessing lower limb muscle mass, with lower costs and lower radiation dose, while inter-observer and intra-observer variability are low.Key points• Screening for sarcopenia should be optimized as the population ages.• DXA outperformed CT and MRI in the measured metrics.• DXA validity should be further evaluated as an alternative to CT and MRI for sarcopenia evaluation.Graphical Abstract
