Riassunto

La scansione total body consente un’analisi a tre compartimenti dell’intero corpo (Figg. 36.1 e 36.2) grazie alla quale è possibile ottenere con un’unica scansione i risultati relativi alla misurazione totale e distrettuale della massa ossea espressa in BMD (Fig. 36.3) e della composizione corporea, distinta in massa grassa (fat mass, FM) e massa magra (lean mass) espressa in termini di kg o in valore % totale e distrettuale (Fig. 36.4). Le proteine, il glicogeno, l’acqua e la materia organica non ossea) sono inclusi nella componente magra.

Scansione densitometrica a raggi X a doppia energia (DXA) total body dell’adulto con mappa sulla base della percentuale di grasso. Notare come tutto il corpo sia compreso nell’area di scansione

Scansione DXA total body dell’adulto. Studio della composizione corporea. Lo scheletro risulta distinto dalla massa muscolare e grassa

Scansione DXA total body dell’adulto. Risultato relativo alla sola componente scheletrica

Scansione DXA total body dell’adulto. Risultato relativo alla componente magra (Lean mass) e grassa (Fat mass)
