18F-FDG coincidence imaging for the detection of benign and malignant neoplasm

Objective To evaluate 18F-FDG coincidence imaging for the detection of benign and malignant tumor diagnosis.Methods Retrospectively analyzing 135 18F-FDG dual head coincidence imaging results whose patients had unknown lesions,and comparing with conventional radiographic examination results.The diagnosis of lesion is based on surgical pathology and clinical follow-up.Results Eighty-six of all the 135 patients were diagnosed as malignant lesions(of 95 niduses),49 of all the cases were benign lesion (of 53 niduses).18F-FDG coincidence imaging detected 38 more niduses than conventional radiographic examination,where the niduses reduced by only eight.The sensitivity,specificity and accuracy of the 18F-FDG coincidence imaging in diagnosing carcinoma were 90.7％ (78/86),87.8％ (43/49) and 89.6％ (121/135).Conclusion 18F-FDG coincidence imaging is more sensitive,accurate in detecting benign and malignant tumor,and helps to clinical diagnosing and selecting patients to provide reliable basis for treatment options.
