| 摘 要： | 目的：评价^18F-FDG PET／CT对不明原因腹水的诊断价值。方法：对经B超、胃肠内窥镜和（或）消化道造影、CT和（或）MRI、各种生化和腹水细胞学检查无法确定病因的22例腹水患者进行^18F—FDG PET/CT全身显像。受试者做完PET/CT检查后，由两位有经验的医师独立阅片。结果判断应用目测法和半定量分析方法（标准摄取值，SUV）。结果：22例腹水原因待查的患者行PET／CT检查后，经病理及随访证实其中恶性腹水14例，其它原因所致腹水4例，不明原因者4例。14例恶性腹水患者中，7例PET／CT可检出原发灶（50％），7例假阴性。4例其它原因所致腹水中，3例经PET／CT检查后明确了病因，另1例为结核性腹膜炎，PET/CT误诊为恶性病变。总的诊断符合率为45．5％（10／22）。结论：在腹水病因探查中，^18F-FDG PET／CT显像与其它传统影像学检查相比是一种更为有效、灵敏的手段。

| Abstract: | Objective： To evaluate the diagnostic value of ^18F-FDG PET/CT for the patients with ascites of unknown causes. Methods： Twenty-two patients with ascites of unknown cause refered to our department for whole-body ^18F-FDG PET/ CT. The causes of their ascites could not be confirmed by ultrasound, endoscope and/or radiographic imaging, CT and/or MRI, and diagnostic paracentesis for biochemical content and cytology. The images were interpreted by visual inspection and semi- quantitative analysis（standardized uptake value, SUV）. Results： According to the results of follow-up and pathology, 14 patients were confirmed as malignant ascites, 4 ascitic patients were caused by other reasons, the causes of ascites were still unknown in 4 patients. In the 14 patients of malignant ascites, in 7 patients primary focus were found by ISF-FDG PET/CT and 7 patients were false negative. 10/22 cases （45.5%） were correctly diagnosed. Conclusions： ^18F-FDG PET/CT was a more sensitive and effective method in finding the causes of ascites compared with traditional imaging methods. |
