【摘要】 目的:评价18F-脱氧葡萄糖(18F-fluorodeoxyglucose,18F-FDG)PET/CT显像在肾上腺肿瘤诊断中的应用价值。方法:回顾性分析42例肾上腺肿瘤患者的全身18F-FDG PET/CT及CT平扫加增强的影像学资料,比较两者对肾上腺肿瘤的诊断价值。结果:42例中,原发性肾上腺肿瘤30例,均经手术病理证实。其余12例为转移性肾上腺肿瘤,肾癌转移4例,肺癌转移7例,肝癌转移1例。18F-FDG PET/CT检查阳性42例,敏感度100%,良性病变的SUV值为1.1-2.6,平均1.8,恶性病变的SUV值为2.5-12.3,平均6.0。良恶性病变的SUV值差异有统计学意义(P<0.01)。CT平扫加增强检查阳性38例,敏感度90.5%。PET/CT对肾上腺肿瘤的敏感度明显高于CT,两者差异有统计学意义(P<0.05)。结论:18F-FDG PET/CT在肾上腺肿瘤诊断中具有重要价值,敏感度高于CT。更多还原

【Abstract】 Objective:To evaluate the clinical role of F-18 fluorodeoxyglucose(FDG)-positron emission tomography(PET) in the diagnosis of adrenal disease.Methods: 18F-FDG PET/CT was performed retrospectively in 42 cases with adrenal tumor and compared with CT.Results: Of 42 cases,30 cases were primary adrenal tumors confirmed by surgery and pathology.12 cases were metastasistic adrenal tumors.The primary focus were kidney cancer(4 cases),lung cancer(7 cases) and liver cancer(1 case).The sensitivity of 18F-FDG PET/CT and CT imaging were 100%,90.5%.A statistic difference in standardized uptake value was found between the benign and malignant lesions(P<0.01).Conclusion: The sensitivity of 18F-FDG PET/CT possesses super sensitivity for the diagnosis of adrenal tumors comparing with CT.It may have an important role in the diagnosis of adrenal tumor.更多还原
