摘要
目的评价磁共振全身弥散技术(WB-DWI)的临床应用意义。方法取正常志愿者100例行骨骼WB-DWI扫查,回顾性分析既往以WB-DWI联合CT确诊49例肿瘤患者诊断情况。结果 骨骼WB-DWI扫查结果 正常,未见骨病变,男性ADC与SNR水平低于女性,青年ADC、SNR高于中年人,中年人高于老年人,差异具有统计学意义(P<0.05)。结论 WB-DWI技术适用于全身骨骼、脏器、淋巴结等系统组织病变筛查,对骨骼辨析度高,筛查空肠脏器病变效用尚有待提高。
Objective Evaluation of whole-body magnetic resonance diffusion technique （WB-DWI） and the clinical significance. Methods Take 100 normal volunteers underwent WB-DWI bone scan, a retrospective analysis of the past by WB-DWI combined with CT confirmed 49 cases of patients with diagnosis of tumor cases. Results WB-DWI bone scan were normal, no bone lesions, ADC and SNR levels of less than male female, young ADC, SNR higher than the middle-aged, middle-aged people than older people, with significant difference （P〈0.05）. Conclusion WB-DWI technology is suitable for systemic bones, organs, lymph nodes lesions on skeletal system screening, identification of the high, jejunum organ diseases screening utility is still to be improved.
