磁共振弥散成像在恶性肿瘤疗效评估中的研究价值

目的探讨弥散成像在恶性肿瘤疗效评估中的研究价值。方法对35例拟诊恶性肿瘤患者,分别于治疗前、治疗开始后1个月分别行MR平扫、增强及弥散加权成像检查,测量治疗前、后不同时间点肿瘤最大径和ADC值,分析各疗效组治疗前后不同时间点肿瘤最大径和恶性肿瘤ADC值的动态变化趋势,对弥散加权成像在恶性肿瘤疗效评估进行探讨。结果 PR组治疗前、治疗后1个月ADC值分别为（0.93±0.09）×10-3mm2/s、（1.21±0.17）×10-3mm2/s,SD组治疗前、治疗后1个月ADC值分别为（0.93±0.09）×10-3mm2/s、（1.15±0.17）×10-3mm2/s。结论弥散成像对恶性肿瘤疗效可以进行早期评估。

Study on the value of diffusion-weighted magnetic resonance imaging in evaluating the curative effect of malignant tumor

Objective To investigate the value of diffusion-weighted imaging in evaluating the curative effect of malignant tumor. Methods 35 cases of the patients were malignant tumors, prior to beginning treatment, I months after treatment were performed MR plain scan, enhanced and diffusion weighted imaging, measured before treatment, at different time points after the maximal tumor diameter and ADC value, analysis of the dynamic change trend of different time points of maximum tumor diameter and tumor ADC the effect of group therapy, carries on the discussion to the diffusion-weighted imaging in malignant tumor curative effect evaluation. Results PR group before treatment, l months after treatment the ADC values were （0.93±0.09）× 10-3mm2/s, （1.21±0.17）× 10-3mm2/s, SD groups before treatment, I months after treatment the ADC values were （0.93±0.0）×10-3mm2/s, （1.15±0.17）×10-3mm2/s. Conclusion Diffusion-weighted imaging for early evaluation of curative effect of malignant tumor.
