Figure 9 Pitfall related to the incorrect CT threshold used for the assessment of lung blood volume. A: Iodine defects were seen when the maximum threshold was set at -600 Hounsfield units; B: Lung parenchyma showed normal perfusion when the threshold was changed to -300 Hounsfield units. A higher threshold was needed in children to compensate for the higher lung density.
