We selected 200 Caucasian patients from March 2010 to July 2011 who had to perform a CT scan for cancer restaging. The mean age is 64.5 years. Both sexes are represented by the same number of persons. Patients have executed a total body CT scan with contrast; once scan accomplished, we measured height through a digital scales. We analyzed CT scans of each patient, obtaining multiplanar reconstruction in sagittal and coronal planes with 1 mm of thickness, and we measured 10 diameters of skull and femur. Then we performed a single and a multiple regression analysis considering the three diameters that better correlated with height.
The skeletal diameters with the highest correlation coefficients with stature were femur lengths, length of cranial base (Ba-N), and distance from the posterior extremity of the cranial base to the inferior point of the nasal bone (Ba-NB).
Although both femur and skull are skeletal segments used for stature estimation, in our sample femur gave stronger correlation with height than skull.
h = 35.7 + 1.48¡¤BaN + 2.32¡¤BaNB + 2.53¡¤FEM and h = 3.06¡¤FEM + 72.6 are the formulae that provided the most accurate stature assessment using multiple and single regression analysis respectively.
