Results of the first matched patient study comparing the new Siemens protocol to the GE reference protocol. a, c Scatter plots of the two matched patient groups showing a relationship between CTDIvol and patient BMI, and liver standard deviation and BMI, respectively. b, d The same data grouped by BMI category. The error bars indicate the range of each group. The two Siemens patients with a CTDIvol above 5 mGy in a are the patients that prompted the optimisation of the protocol for the obese patient group
