摘要
目的:评价全身^(18)F-脱氧葡萄糖(^(18)F-fluorodecxyglucose,^(18)F-FDG)正电子发射断层扫描(positron emission tomography,PET/CT)显像在颅内占位性病变中的诊断价值。方法:回顾性分析143例颅内占位性病变患者的全身^(18)F-FDG PET/CT显像及临床随访结果。结果:本组143例患者中,PET/CT诊断脑胶质瘤10例、脑膜瘤7例、淋巴瘤2例、病变性质不明或其它类型肿瘤16例。脑转移瘤108例,确诊原发灶96例,未明确原发灶12例,原发灶检出率为88.9%,其中原发灶为肺癌的65例,占67.7%,消化系统来源恶性肿瘤17例,占17.7%,生殖系统来源恶性肿瘤3例,占3.1%,不同来源脑转移瘤间差异无统计学意义。结论:颅内占位性病变病人^(18)F-PET/CT显像可有效发现脑内病灶和脑转移瘤中的原发灶,并可大致区分原发灶类型,脑转移瘤来源于肺恶性病变居多。
Objective： To evaluate diagnostic value of whole-body^18F-fluorodecxyglucose^18F-FDG positron emission tomography imaging in brain accounted for lesions. Methods： Retrospectively analyse 143 patients with intracranial space occupying lesions of the brain and body PET/CT^18F-FDG imaging and clinical follow-up results.Results： In 143 cases of patients,10 cases of PET/CT in the diagnosis of glioma,meningioma in 7 cases,lymphoma in2 cases,unknown,or other types in 16 cases. In 108 cases of brain metastases,96 cases of primary tumors were confirmed,12 cases were not clear,but the detection rate was 8 8. 9 %,including 6 5 cases deriving from lung cancer（ 67. 7%）,17 cases of the digestive system（ 17. 7%）,3 cases of reproductive system（ 3. 1%）. Conclusion： Intracranial space occupying lesions in patients^18F-PET/CT imaging effectively find primary brain tumors and metastases,and can roughly distinguish the pathological type and evaluate the therapeutic effect. Brain metastasis tumor derived from malignant lung lesions more.
