摘　　要：正电子发射断层显像通过检测病灶对示踪剂的摄取程度反映细胞及组织的功能代谢状态,从而进一步显示全身肿瘤及非肿瘤性病变。磁共振全身弥散加权成像是崭新的磁共振成像技术,在评价肿瘤分期、筛查良恶性病变方面具有广阔的应用前景。作为两种可以进行全身显像的技术,明确各自优势并合理选择是十分必要的。本文主要针对二者在肿瘤及炎症疾病中的诊断价值及研究进展展开综述。Position emission tomography detects the uptake of tracer to reflect the functional and metabolic status of ceils and tissues in order to further diagnose malignant and benign lesions. Whole body diffusion-weighted imaging is a new technique of functional magnetic resonance imaging. It has a broad prospect in screening lesions and evaluation of cancer staging. As two kinds of techniques that can be used for whole body imaging, it is necessary to make clear the advantages and reasonable choices of each of them. This article reviews the diagnostic value and research progress of the two in tumor and inflammatory diseases.
