近年来,功能性显像技术在淋巴瘤诊疗中逐渐占据重要地位。用于淋巴瘤诊疗的核医学影像技术主要包括单光子发射型断层扫描技术(SPECT)、正电子发射型断层显像(PET)、正电子发射型断层/计算机体层摄影术(PET/CT)。67Ga-枸橼酸较早用于诊断淋巴瘤的功能性显像,后逐渐被18F-FDG取代。PET/CT的应用实现了功能影像与解剖影像有机结合及优势互补,对淋巴瘤的定位、定性及分期更准确,在淋巴瘤的诊疗方面显示出重要的临床应用价值。本文对18F-FDG PET及PET/CT在淋巴瘤诊疗方面的应用现状进行综述。
In recent years, functional imaging technology gradually occupies an important position in the diagnosis and treatment of lymphoma. Nuclear medicine imaging techniques used in the diagnosis and treatment of lymphomas mainly include single photon emission tomography (SPECT), positron emission tomography (PET), positron emission tomography / computed tomography (PET / CT) . 67Ga-citric acid earlier used to diagnose functional imaging of lymphoma, gradually replaced by 18F-FDG. The application of PET / CT has realized the combination of functional imaging and anatomical imaging, and has the advantages of complementarity. It is more accurate for the localization, characterization and staging of lymphomas and has shown important clinical application value in the diagnosis and treatment of lymphomas. This article reviews the current status of 18F-FDG PET and PET / CT in diagnosis and treatment of lymphoma.
