Figure 1 Patient Radiation Dose Versus Fluoroscopy Time and BMI
Scatter plots showing the relationship between patient radiation dose and total fluoroscopy time (A) and body mass index (BMI) (B). There is a significantly stronger correlation between BMI and radiation dose than between fluoroscopy time and radiation dose. DAP = dose-area product; PDiff(R1-R2) = p value for difference between correlation coefficients; R1,2 = correlation coefficients.
