摘要
正电子发射断层与计算机断层成像（PET/CT）是将PET与CT 2种图像加以融合,PET提供病灶的代谢信息,CT显示病灶的解剖特征.利用PET/CT进行一次扫描可获得全身断层图像,可以高度敏感地反映体内生理及生化过程并对其精确定位.自1998年PET/CT机用于医疗体系以来,作为临床上重要的影像学诊断工具,近年来已被逐渐应用于检测眼部肿瘤,如脉络膜黑色素瘤、脉络膜转移癌、视网膜母细胞瘤、眼部淋巴瘤、泪腺腺样囊性癌等.就PET/CT的原理、标准摄取值（SUV）在临床中的应用价值以及PET/CT在眼部的临床应用进展进行综述.
Positron emission tomography and computed tomography （PET/CT） fusion combines the advantages of both imaging modalities （quantification of metabolic activity and anatomic localization of tumor）.With once scan,whole-body imagings can obtain with highly sensitivity to reflect the physiological and biochemical processes of the body and accurate position about the lesions.As an important clinical imaging diagnostic tool,since the first combined PET/CT scanner introduced to the medical community in 1998,it＇s has been gradually applied in the detection of ophthalmic tumors in recent years,such as choroidal melanoma,choroidal metastatic carcinoma,retinoblastoma,ocular lymphoma,adenoid cystic carcinoma of lacrimal gland etc.In this paper,the principle of PET/CT,the clinical application value of standardized uptake value （SUV） and the clinical application of PET/CT in ocular tumors were summarized.
