Riassunto
L’utilizzo della tomografia computerizzata ha registrato negli ultimi anni un forte incremento, motivato dalla sua grande capacità di fornire una diagnosi rapida e accurata in un numero sempre più elevato di patologie, sostituendo altre tecniche diagnostiche in numerose indagini cliniche [1, 2]. Tale situazione ha determinato un progressivo e sostanziale aumento del numero de gli esami eseguiti (con un incremento annuo di oltre il 10%), portando la tomografia computerizzata a rappresentare la principale fonte di radiazioni per il paziente che si sottopone a procedure di diagnostica per immagini, con esami che possono erogare livelli di radiazioni tutt’altro che trascurabili [3, 4]. Recentemente, sia nella comunità scientifica che tra i mezzi di comunicazione di massa è cresciuta una particolare preoccupazione per i possibili danni provocati ai pazienti proprio in conseguenza del crescente ricorso alla TC, spingendo gli operatori sanitari verso una maggiore attenzione e consape- volezza nella valutazione dei rischi connessi, spesso sottostimati se non addirittura misconosciuti [5, 6].
