目的：探讨磁共振弥散加权成像技术在肝癌介入治疗中的应用价值。方法以我院放射科收治的32例行介入治疗的肝癌患者为研究对象，根据其临床资料进行回顾性分析和总结，分别在其介入治疗前和介入治疗后7天对其进行常规平扫和磁共振弥散加权成像扫描，观察患者的影像学特征，并比较不同扩散敏感梯度值(b值)下的ADC值。结果治疗前患者的肿瘤体积为(204.93±122.89)cm3，治疗后下降到(145.37±117.26)cm3，治疗后的肿瘤体积明显低于治疗前，p＜0.05，差异显著；b值为50、100时其治疗前后的ADC值没有显著差异，而当b值为300、500、700时治疗前后的ADC值存在显著差异(p＜0.05)。结论磁共振弥散加权成像技术在肝癌介入治疗中的应用价值较高，其影像具有一定的特征性，可以反映肿瘤形态的微小变化，观察患者介入治疗后肿瘤血管密度等病理变化情况，对其治疗效果进行评定，具有较高的临床应用推广价值。

Objective This Paper is to investigate the application value of magnetic resonance diffusion weighted imaging in interventional therapy of liver cancer. Methods Thirty two patients with liver cancer admitted by the Radiology Department of the Hospital undergoing interventional treatment of liver cancer patients were selected as research objects, who were retrospectively analyzed and summarized according to clinical data, those patients underwent routine scanning and magnetic resonance diffusion weighted imaging scanning respectively before interventional treatment and 7 days after interventional treatment, imaging characteristics of patients were observe, and ADC indexes under different diffusion sensitive gradient values (b) were compared. Results The gross tumor volume of patients before treatment 204.93+/-122.89cm3, and it fell to 145.37+117.26cm2 after treatment, the gross tumor volume of patients after treatment was significantly lower than that of patients before treatment (p<0.05), and differences were significant. There was no significant difference in ADC indexes before and after the treatment when the value of b hit 50 and 100, and there were significant differences in ADC indexes before and after the treatment when the value of b hit 300, 500 and 700 (p<0.05). Conclusions Magnetic resonance diffusion weighted imaging deliver great value in interventional therapy of liver cancer, its images deliver certain characteristics, insignificant changes in the form of tumor may be reflected, and pathological change in tumor vascular density of patients may be observed, and the evaluation on treatment efficacy is of high application and promotion value in clinical practices.
