Fig. 1. From: Is Weight-Based Adjustment of Automatic Exposure Control Necessary for the Reduction of Chest CT Radiation Dose?.

Scatter plot of radiation dose (CTDIvol-y-axis) versus patient transverse diameter (cm) (x-axis) showing moderate correlation for chest CT performed by non-weight-adjusted automatic exposure control technique (correlation coefficient = 0.61) (A). Strong correlation (correlation coefficient = 0.83) was observed for chest CT performed by weight-adjusted automatic exposure control technique (B).

Fig. 2. From: Is Weight-Based Adjustment of Automatic Exposure Control Necessary for the Reduction of Chest CT Radiation Dose?.

Scatter plot graph of radiation dose (CTDIvol - y-axis) versus patient weight (kg) (x-axis) shows moderate correlation for chest CT performed by non-weight-adjusted automatic exposure control technique (correlation coefficient = 0.66) (A). Strong correlation (correlation coefficient = 0.83) was observed for chest CT performed by weight-adjusted automatic exposure control technique (B).

Fig. 4. From: Is Weight-Based Adjustment of Automatic Exposure Control Necessary for the Reduction of Chest CT Radiation Dose?.

2.5 mm thick transverse chest CT performed with weight-adapted automatic exposure control technique for lung (A) and mediastinal (B) windows in 46-year-old male (patient weight 107 kg, objective noise 10.5, and CTDIvol 28.0 mGy). Chest CT examinations using non-weight-adjusted automatic exposure control technique in 58-year-old male (patient weight 107 kg, objective noise 10.6, and CTDIvol 39.6 mGy) for lung (C) and mediastinal (D) windows. At lower radiation dose, weight-based automatic exposure control protocols provides acceptable image noise and diagnostic acceptability.

Fig. 3. From: Is Weight-Based Adjustment of Automatic Exposure Control Necessary for the Reduction of Chest CT Radiation Dose?.

2.5 mm thick transverse chest CT performed by weight-adapted automatic exposure control technique in lung (A) and mediastinal (B) windows in 76-year-old female (weight 43 kg, objective noise 8.1, and CTDIvol 12.8 mGy). Chest CT examination with non-weight-adjusted automatic exposure control technique in 43-year-old female (weight 45 kg, objective noise 8.9, CTDIvol 18.0 mGy) in lung (C) and mediastinal (D) windows. At lower radiation dose, weight-adjusted automatic exposure control protocol provides acceptable image noise and diagnostic acceptability.
