TABLE 5.

Examination-based interpretation. For both “bone” and “soft tissue” “doubt” was only quoted if no focus evocative of malignancy was observed. % correspond to the frequency of this interpretation for each modality; since fluorodeoxyglucose(18F) (FDG) PET/CT and fluorocholine(18F) (FCH) PET/CT can detect foci in the prostatic bed, the soft tissue and the skeleton, the total is greater than 100%

Interpretation	Number of examinations	Negative	Doubt bone	Bone metastasis	Prostate focus	Doubt soft tissue	Malignant soft tissue
BS	132	65 (49%)	37 (28%)	30 (23%)	0	0	0
FNa PET/CT	146	79 (54%)	32 (22%)	35 (24%)	0	0	1 (1%)
FDG PET/CT	35	2 (3%)	1 (3%)	29 (83%)	1 (3%)	3 (9%)	8 (23%)
FCH PET/CT	375	52 (14%)	15 (4%)	86 (23%)	198 (53%)	21 (6%)	132 (35%)
