摘　　要：随着社会不断发展,肿瘤发病率呈逐年升高态势,提升早期病灶检出率有助于临床医生制订有效诊疗方案,对提高肿瘤患者生存率及生活质量意义重大。全身磁共振成像(whole body-magnetic resonance imaging,WB-MRI)对早期肿瘤病灶检出及肿瘤高危人群筛查具有巨大优势。WB-MRI具有无电离辐射、软组织分辨率高的特点,能够弥补正电子发射计算机断层扫描(positron emission tomography/computed tomography,PET/CT)辐射剂量大、软组织分辨率低的缺点,并在实际应用中得到验证。WB-MRI可应用于肿瘤早期病灶检出、影像诊断、临床分期、治疗效果评估等方面,同时可敏感检测出转移性骨肿瘤的骨质破坏情况及血液性肿瘤的骨髓浸润。综上,本文针对WB-MRI在呼吸系统肿瘤、消化系统肿瘤、血液系统肿瘤、骨转移肿瘤检出以及肿瘤高危人群筛查方面的临床应用进展作一综述。With the continuous development of society,the incidence of cancer is increasing year by year.Improving the early detection rate of lesions is helpful for clinicians to formulate effective diagnosis and treatment plans,which is of great significance to improve the survival rate and quality of life of cancer patients.Whole body-magnetic resonance imaging(WB-MRI)has great advantages in early detection of tumor lesions and screening of tumor high-risk population.WB-MRI has no ionizing radiation and high resolution of soft tissue,and it can make up for the disadvantages of high radiation dose and low soft tissue resolution in positron emission tomography/computed tomography(PET/CT),and has been verified in practical application.It can be used in early tumor lesion detection,imaging diagnosis,tumor clinical staging and therapeutic effect evaluation.At the same time,the bone destruction of metastatic bone tumor and the bone marrow infiltration of hematological tumor can be detected out.Through reviewing a large number of literatures,the author found that WB-MRI has the advantages of high accuracy and sensitivity in the detection of hematologic tumors and bone metastases as well as the screening of tumor high-risk groups.To sum up,this paper reviews the clinical application progress of WB-MRI in the detection of respiratory system tumors,digestive system tumors,hematologic tumors and bone metastases as well as the screening of tumor high-risk population.
