| 目的 探讨18F-FDG PET/CT显像对不明原因腹腔积液患者的诊断价值。方法 回顾性分析96例不明原因腹腔积液患者的PET/CT资料,将病理及临床随访结果与PET/CT进行对照。结果 96例患者中,75例为腹膜恶性肿瘤(腹膜转移瘤69例,腹膜间皮瘤4例,假黏液瘤2例);21例为良性腹膜炎(17例腹膜结核,4例细菌性腹膜炎)。PET/CT诊断腹膜良恶性病变的灵敏度、特异度和准确率分别为94.67%(71/75)、71.43%(15/21)和89.58%(86/96)。腹膜良、恶性病变的SUVmax分别为7.91±4.01和6.03±3.19(t=-2.25,P<0.05)。18F-FDG代谢范围与CT病灶范围的比较对鉴别腹膜良恶性病变差异有统计学意义(χ2=35.36,P<0.01)。结论 18F-FDG PET/CT在鉴别良恶性腹腔积液方面有重要价值,尤其是对肿瘤原发灶的检出,但在诊断腹膜结核时易引起假阳性,故应当密切结合临床资料和其他检查以减少误诊。 |

| Objective To evaluate the value of 18F-FDG PET/CT in diagnosis of ascites of undetermined origin. Methods Totally 96 patients with ascites of undetermined origin were retrospectively analyzed. The PET/CT imaging results were compared with pathology and clinical follow-up reports. Results There were 75 patients with malignant diseases including peritoneal metastasis (n=69), peritoneal mesothelioma (n=4) and pseudomyxoma peritone (n=2), and 21 with benign peritonitis including peritoneal tuberculosis (n=17) and bacterial peritonitis (n=4). The sensitivity, specificity, and accuracy of PET/CT in detecting the cause of ascites were 94.67% (71/75), 71.43% (15/21) and 89.58% (86/96), respectively. SUVmax was statistical significance between peritoneal benign and malignant lesions (7.91±4.01 vs 6.03±3.19; t=-2.25, P<0.05). There was also statistical significance to compare the scope of 18F-FDG and CT in the diagnosis of ascites (χ2=35.36, P<0.01). Conclusion 18F-FDG PET/CT offers higher value in the differential diagnosis of ascites, especially in detecting the primary tumor. In the diagnosis of peritoneal tuberculosis, 18F-FDG PET/CT can lead to a false positive, which should be closely combined with clinical data and other checks to reduce misdiagnosis. |
