PET/CT is an advanced imaging modality that is becoming more commonly used in veterinary medicine. It is most commonly used to image patients with cancer, and the most frequently used radiopharmaceutical is F-18 FDG. F-18 FDG is a glucose analog that highlights areas of increased glucose metabolism on the PET images. CT images provide excellent anatomic depiction and aid in interpretation of the PET data. Many types of cancer are hypermetabolic on PET/CT scans, but normal structures and areas of inflammation are also hypermetabolic, so knowledge of normal imaging and cytologic or histopathologic evaluation of lesions is essential.
正电子发射断层扫描/计算机断层扫描（PET/CT）是一种先进的成像方式，在兽医学中越来越常用。它最常用于对患有癌症的患者进行成像，最常用的放射性药物是氟-18氟代脱氧葡萄糖（F-18 FDG）。F-18 FDG是一种葡萄糖类似物，可在PET图像上突出显示葡萄糖代谢增加的区域。CT图像能提供出色的解剖结构描绘，并有助于对PET数据进行解读。许多类型的癌症在PET/CT扫描中表现为代谢亢进，但正常结构和炎症区域也会代谢亢进，因此了解正常成像以及对病变进行细胞学或组织病理学评估至关重要。
