Core Tip

Core tip: Accumulation of intra-abdominal visceral fat correlates with atherogenic and metabolic abnormalities, collectively known as the metabolic syndrome. Visceral adiposity is an important component of the syndrome in Japanese individuals with mild adiposity compared with Western subjects. A computed tomography (CT) scan allows the separate analysis of subcutaneous fat and visceral fat, and the visceral fat area (VFA) from a single CT slice L4 level correlates with total visceral fat volume. A VFA cut-off value of 100 cm2 is used for risk assessment of obesity-related disorders.
