Objective: The objective was to evaluate the performance of ADC as a predictor of treatment outcomes associated with WBRT and chemotherapeutic agents in patients affected by lung adenocarcinoma (LUAD) originating in brain metastases (BMs). Methods: A retrospective analysis was conducted of 60 patients with LUAD with BMs who underwent WBRT and chemotherapy at the Affiliated Hospital of Qingdao University from July 2019 to July 2023, and measured the ADC value by DWI imaging before and within 12 weeks after treatment. According to the response evaluation criteria in solid tumors (RECIST), the efficacy was evaluated, and the relationships between pre-ADCmean and δADC values on MRI diffusion-weighted imaging and the efficacy of radiotherapy and chemotherapy were discussed. Results: Among the 60 patients, there were 32 responded to chemoradiotherapy, while 28 did not. The pre-ADCmean values of the effective group was higher than that of the ineffective group (P < 0.05). The ROC analysis showed that the pre-ADCmean value had a predictive value for the efficacy of concurrent chemoradiotherapy in patients with multiple brain metastases from lung adenocarcinoma, with an area under the curve (AUC) of >0.70. Conclusion: The apparent diffusion coefficient of 3.0T-MRI diffusion-weighted imaging can predict the efficacy of whole brain radiotherapy combined with chemotherapy for multiple brain metastases from lung adenocarcinoma. %K 表观扩散系数， %K 肺腺癌， %K 多发脑转移， %K WBRT
