摘　　要：目的探讨分析磁共振3D-ASL联合DTI技术在脑转移瘤放射治疗疗效评估中的应用价值。方法纳入2023年1月至2024年6月在内蒙古包钢医院就诊的40例脑转移瘤患者,给予磁共振3D-ASL联合DTI技术检查,观察对比感兴趣区的CBF、FA、ADC值。结果3D-ASL联合DTI对脑转移瘤转移病灶数目的检出率高于MRI常规扫描与DCE-MRI扫描,P<0.05。治疗后1个月、6个月,病灶的CBF值、ADC值与治疗前1周相比,P<0.05。放射治疗前后不同时期FA值对比,P>0.05。结论磁共振3D-ASL联合DTI技术可反映脑转移瘤患者放射治疗后的病理学变化,对疗效具有较高的评估价值。Objective:To explore and analyze the application value of magnetic resonance 3D-ASL combined with DTI in the evaluation of radiotherapy for brain metastases.Methods:Forty patients with brain metastases from January 2023 to June 2024 in Baotou Steel Hospital of Inner Mongolia were examined by 3D-ASL combined with DTI,and the values of CBF、FA and ADC in the region of interest were observed and compared.Results:The detection rate of 3D-ASL combined with DTI was higher than that of conventional MRI scanning and DCE-MRI scanning,P<0.05.One month and six months after treatment,the CBF value and ADC value of the lesion were compared with those of the week before treatment,P<0.05.The FA values of different periods before and after radiotherapy were compared,P>0.05.Conclusion:MRI 3D-ASL combined with DTI can reflect the pathological changes of patients with brain metastases after radiotherapy,and has high evaluation value for curative effect.
