Introduction:
Several study supported that 18F-Fluoro-deoxy-glucose (FDG) positron emission tomography/computer tomography with low dose CT (standard PET/CT) is more accurate than contrast-enhanced CT (ceCT) in the primary staging of Hodgkin disease.
Aim:
The authors compared the accuracy of these examinations with this indication in their practice, and analysed the added value of ceCT which was performed as a supplement to standard PET/CT.
Method:
Twenty-eight patients were categorized based on ceCT, single standard PET/CT and standard PET/CT with ceCT.
Results:
Twenty-four patients were in the same disease-stage based on all methods. Disease was upstaged by standard PET/CT compared to ceCT in 4 patients. There was no change in stage when comparing standard PET/CT and standard PET/CT with ceCT.
Conclusions:
Standard PET/CT is more accurate than ceCT in the primary staging of Hodgkin disease. The authors established that it is not reasonable to supplement standard PET/CT with ceCT in this indication.
