^18F-FDG PET/CT在胸腔积液鉴别诊断的研究进展

Progresses of ^18F-FDG PET/CT in differential diagnosis of pleural effusion

正电子发射断层显像/电子计算机断层显像（PET/CT）检查主要应用18氟-氟代脱氧葡萄糖（^18F-FDG）作为显像剂,通过观察病灶对显像剂的摄取情况判断其代谢情况,进而做出诊断,可同时提供解剖和功能显像,既能定位诊断,又可定性诊断,明显提高了疾病诊断的正确率.目前PET/CT在临床上已被广泛用于良恶性肿瘤的鉴别诊断、预后评估等多个方面.胸腔积液的性质对于疾病的治疗及预后有重要意义.

^18F-2-fluro-D-deoxy-glucose （^18F-FDG） is used by positron emission tomography/computed tomography （PET/CT） examination as an imaging agent,by observing the uptake of the agent of the lesion to determine its metabolism,and make a diagnosis.It can provide anatomical and functional at the same time,not only qualitative but also position and can significantly improve the accuracy of diagnosis.Currently PET/CT has been widely used in the clinical aspects of the differential diagnosis of benign and malignant tumors,prognostic assessment and so on.The property of pleural effusion is important to the treatment and prognosis of the disease.
