Abstract: Objective To compare the diagnostic values of 18F-fluorodeoxyglucose-single photon emission computed tomography (18F-FDG-SPECT) and helical CT in the detection of the metastasis of postoperative breast cancer.Methods A total of 94 patients with postoperative breast cancer were chosen as research objects.The follow-up duration of post-operation was 2 years.All patients were received by 18F-FDG-SPECT and helical CT during follow-up.Lymph nodes that were suspected to the postoperative metastasis were taken for histological procedure.The diagnostic values of 18F-FDG-SPECT and helical CT to the metastasis of postoperative breast cancer were compared.Results Compared to helical CT,the sensitivity,specificity,positive predictive value,negative predictive value,and positive likelihood ratio of 18F-FDG-SPECT were higher (P ＜ 0.05);however,the negative likelihood ratio of 1s F-FDG-SPECT were lower (P ＜ 0.05).Conclusions 18F-FDG-SPECT has more important clinical value in the detection of metastasis of postoperative breast cancer relative to helical CT.
