Feasibility of FDG PET in Inflammatory Bowel Disease

摘要

Positron emission tomography (PET) with 18-fluorodeoxyglucose visualizes hypermeta-bolic disease processes by metabolic trapping. Since its inception in the late 1970s the method has gained widespread use, primarily in oncology for tumor detection, staging and therapy evaluation. Within the last decades it has also become relevant in the field of inflammation, as this too is characterized by focal hypermetabolism. In this review we report on the current literature (22 studies) on the application of PET and its feasibility in inflammatory bowel disease (IBD) compared with other modalities, e.g. endoscopy, in both the adult and pediatric population.
