Conclusion
Our study demonstrated that by increasing the Dose Rateo from 15 to 25 we obtained an increase in the conspicuity of ground glass nodules localized in the apical and basal regions of the lung,
while the pure ground glass nodules localized in the peri-hilar region were not visible.
The intermediate density nodules were still visible even with a Dose Rateo of 10.
The increase in kVp,
from 105 to 125,
did not modify the visibility of the nodules.
Finally,
the pure ground glass nodules can be identified by Digital Tomosynthesis using a Dose Rateo of 15 while the intermediate density nodules can be identified using a Dose Rateo of 10.
In conclusion,
the reduction of the effective dose to the patient could be obtained by reducing the use of CT over time,
replacing it with Digital Tomosynthesis.
