It has various clinical symptoms proceding to the diagnosis of tumors. Although the abnormality of anti-neuronal antibodies is suggestive of PNS and tumors, there exist many false positive and false negative cases. The diagnosis of PNS is usually a challenge in clinic. Positron emission tomography/computed tomography(PET/CT) imaging is an anatomical and functional fusion imaging method, which provides the whole-body information by single scan. Fluorodeoxyglucose(FDG) PET/CT imaging can not only detect potential malignant lesions in the whole body, but also assess functional abnormality in the brain. In this review, the mechanism, clinical manifestation, diagnostic procedure and the recent progress of the utility of FDG PET/CT in PNS are introduced respectively.展开更多

We retrospect a lung histoplasmosis patient, he was examined by the CT scan and ECT scanning, respectively. Results showed that lung cancer for CT diagnosis and large benign lesions for 18F-FDG （18F-fluorodeoxyglucose） ECT diagnosis. This indicated that the ECT diagnosis for benign lesions in the lung maybe have higher accuracy than CT scan.展开更多
