Size-Specific Dose Estimates of Radiation Based on Body Weight and Body Mass Index for Chest and Abdomen-Pelvic CTs

Table 3

Mean values and variation of radiation dose in chest and abdomen-pelvic CT examination across all verified patients.


Parameters	Chest			Abdomen
Parameters	SSDE	SSDE_weight	SSDE_BMI	SSDE	SSDE_weight	SSDE_BMI

Mean values (mGy)
Range (mGy)	13.77	16.83	14.41	10.62	10.70	12.51
COV (%)	27.78	29.39	28.60	12.19	14.34	14.14

Abbreviation: SSDE: size-specific dose estimate; SSDE_weight: size-specific dose estimate based on body weight; SSDE_BMI: size-specific dose estimate based on body mass index; COV (%): the coefficient of variation calculated using standard deviation divided by mean values. Note: mean values are reported as the . Range is the difference between maximum and minimum values of radiation dose.
