The value of dual-time-point 18F-FDG PET/CT for identifying axillary lymph node metastasis in breast cancer patients

摘要

ObjectiveThe sensitivity of 18-fluorodeoxyglucose >(¹⁸F-FDG) positron emission tomography (PET) for detecting axillary lymph node (ALN) metastases in breast cancer is reported to be low. Several studies have shown, however, that dual-time-point ¹⁸F-FDG PET imaging provides improved accuracy in the diagnosis of certain primary tumours when compared with single-scan imaging. The purpose of this study was to assess whether the use of dual-time-point ¹⁸F-FDG PET/CT scans could improve the diagnostic accuracy of ALN metastasis in breast cancer.
