Abstract
Purpose
To assess the computed tomography (CT) portion of a positron emission tomography (PET)/CT,
at lower dose without breath holding, as compared to diagnostic chest CT (dCTC), performed
at regular dose with breath holding, and question the necessity of both for patient
care in pediatric oncology.
Materials and Methods
This retrospective study included 46 pediatric patients with histologically proven
malignant tumors that had a total of 119 scans.
Results
A total of 29 discrepancies were found between dCTC and PET/CT reports.
Conclusion
In the evaluation of metastatic thoracic disease in pediatric oncology patients, the
non-breath holding CT portion of PET/CT has sensitivity and specificity that approaches
dCTC.
