Body composition evaluation with computed tomography: Contrast media and slice thickness cause methodological errors
The first analyses of body composition were used for analyzing muscle loss in astronauts or for evaluating dietary regimes in obese patients [1], but during recent decades body analyses have gained increasing interest when evaluating cancer cachexia [2] and critically ill patients [3]. Initial methodology was based on dual-energy X-ray absorptiometry (DXA), under-water weighing and bioimpedance [4]. These techniques, however, could not distinguish between muscle groups or between subcutaneous and intra-abdominal fat.
