Image measurements (CBCT/MDCT) were performed upon multiplanar reformatted data sets and compared with the anatomical measurements; the number of non-assessable sites (NASs) was evaluated. Results: Radiological measurements were accurate with a mean difference from anatomical measurements of 0.14mm (CBCT) and 0.23mm (MDCT). These differences were statistically not significant, but the limits of agreement for bone measurements were broader in MDCT (21.35 mm; 1.82 mm) than in CBCT (-0.93 mm; 1.21 mm). The limits of agreement for soft tissue measurements in CBCT were smaller (-0.77 mm; 1.07 mm), indicating a slightly higher accuracy. More NASs occurred in MDCT (14.5{\%}) than in CBCT (8.3{\%}).",
