Conclusion and Recommendations
- In conclusion,
we have found that ASIR reconstruction of a single phase post contrast study from a low dose radiation regime did not show any deleterious effects on the efficiency of final diagnosis or conspicuity of any important lesion in patients performing follow-up CT explorations in hematologic malignancies.
- We did not find radically lower image quality in the low-dose regimen with ASIR compared with the standard-dose one reconstructed with filtered-back projection.
- However,
one should consider that in large patients,
a more customized ASIR parameter might be necessary in order to obtain good quality images.
- We recommend using responsible low-dose and iterative reconstruction in CT follow-up of these patients,
using scan protocols customized according to local clinical recommendations and imaging department requisites.
