ABSTRACT
Objective Retrospectively evaluate low dose computed tomography (CT) as part of a combined 18F-NaF positron emission tomography (18F-NaFPET/CT) examination in lung cancer patients suspected of bone metastases. Methods 118 of 122 lesions with increased uptake of 18F-NaF were assessed. Characteristics of bone metastases on CT images were reviewed by radiologists. Results 27 of 47 metastases presented as sites of increased uptake with corresponding lytic or sclerotic changes on low dose CT. Other 20 show normal or non-specific appearing bone on CT. Most benign lesions (67 of 71,94%)have a benign appearance on low-dose CT. Conclusions Low dose CT images were useful in precisely diagnosing bone metastasis. Negative low dose CT appearance to the abnormal foci on PET may be a reliable sign of metastases.
