摘　　要：恶性肿瘤发病率在近年呈现逐年增高的态势,其中有不少肿瘤的原发灶并不明确,不明原发灶肿瘤(UPT)给肿瘤临床治疗带来了困难。根据文献报道,UPT在恶性肿瘤总病例数中占0.5%~9%,而只有20%~27%的死亡病例是有明确的原发病灶的[1]。传统影像学检查在UPT中只能检测到大约20%~35%的原发灶。PET/CT是PET与CT的同机融合,既有PET功能显像高灵敏度的特色。本文回顾分析了近年来我院转移瘤患者,采用PET/CT来寻找原发病灶的显像资料,评估PET/CT在寻找转移瘤原发病灶中的应用价值。The incidence of malignant tumors increases year by year in recent years.The primary site of many tumors are not clear.The unknown primary tumor(UPT)has brought difficulties to the clinical treatment.According to the literature,UPT accounts for 0.5%-9%of the total cases of malignant tumors,while only 20%-27%of the deaths have definite primary lesions.Only about 20%to 35%of the primary foci can be detected in the UPT by traditional imaging.PET/CT is the combination of PET and CT,which has the characteristics of high sensitivity of PET functional imaging.This paper reviews the imaging data of primary lesions by PET/CT in our hospital,and evaluates the value of PET/CT in the search for primary metastasis.
