Correlation of Size-Dependent Conversion Factor and Body-Mass-Index using Size-Specific Dose Estimates formalism in CT examinations

Conclusion This study demonstrates that it is possible to estimate fsize by using the patients’ BMI for the torso as well as the head and knee CT, thereby enabling calculation of the probable SSDE prior to image acquisition on the basis of the presumed CTDIvol provided by the scanner. By providing information on the expected patient dose prior to image acquisition, this method is advantageous over the traditional calculation of fsize via the AP and LAT dimensions.
