摘　　要：目的探讨磁共振(MR)全身类正电子发射断层成像(Positron Emission Tomography,PET)技术对"健康人群"肿瘤普查的应用价值。方法选择1056例无明确肿瘤病史,做磁共振常规部位检查的病人,在常规部位检查同时加扫全身弥散加权成像(Diffusion Weighted Imaging,DWI)。结果发现35例42个病灶,DWI图像上均呈高信号,ADC图为低信号,每个病灶ADC值均与正常区域比较明显降低,降低幅度>50%。上述病灶均经临床证实为恶性病变或转移瘤。结论磁共振全身类PET技术可以发现肿瘤原发灶及转移灶,具有无辐射、无需注射造影剂、检查简便快捷的优势,适合于"健康人群"肿瘤筛选。Objective To investigate the application value of MRI PET imaging technology for tumor screening of healthy people. Methods 1056 cases of patients who got MRI and did not have tumor history were selected to do diffusion weighted imaging. Results 35 cases with 42 lesions showed high signal on DWI and low signal on ADC images. Compared with the normal region, the ADC value of each lesion was decreased significantly （〉 50%）. These lesions are clinically proven to be malignant lesions or metastatic lesion. Conclusion MRI PET technology can detect primary lesions and metastatic lesions, and has advantages of no radiation, no injection of contrast agent, quick detection, is suitable to tumor screening in healthy people.
