PET/CT检查是一种全身性检查手段,其利用了PET和CT两种不同成像原理的设备,一次检查即可获取全身各方位的断层功能融合图像。 PET/CT检查已成为诊断早期肿瘤非常重要的检查手段,尽管其存在对小肿瘤特异性差、假阳性和假阴性、图像有伪影、辐射剂量大、价格昂贵等局限性,但在PET、CT等新技术的不断发展下,PET/CT将克服这些局限性得到更加广泛的应用。

PET/CT examinations are general inspections, which utilize different imaging principle to obtain cross-sectional and functional fusion images of the whole body by only one examination. As an important method for diagnosing early stage tumor, PET/CT examinations have some limitations such as poor specificity of smal tumor, false-positive, false-negative, image artifacts, large radiation dosage, and expensive price. However, PET/CT would overcome these limitations and be used more widely due to the continuous development of new technology of PET and CT.
