摘要
目的:探讨动态增强磁共振成像(DCE-MRI)定量参数联合表观扩散系数(ADC)在评估老年宫颈癌同步放化疗效果中的应用价值.方法:回顾性分析老年宫颈癌患者 121 例临床资料.所有患者均采用同步放化疗,治疗前后均采用常规T1WI、T2WI、DWI、DCE-MRI序列扫描.结果:121 例老年宫颈癌患者同步放化疗后,完全缓解 31例,部分缓解 45 例,稳定 34 例,进展 11 例.结论:Ktrans、Kep、ADC均为评估宫颈癌同步放化疗的有效影像指标,ADC+Ktrans+Kep联合检测有助于提高诊断效能,为老年宫颈癌精准化治疗方案提供参考.
Abstract
Objective:To explore the application value of quantitative parameters of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)combined with apparent diffusion coefficient(ADC)in evaluation of the effect of concurrent chemoradiotherapy in elders with cervical cancer.Methods:The clinical data from 121 cases of elderly patients with cervical cancer were retrospectively analyzed.All patients were treated with concurrent chemoradiotherapy,and conventional T1WI,T2WI,DWI,DCE-MRI sequences were scanned before and after treatment.Results:After concurrent chemoradiotherapy was performed in 121 elderly patients with cervical cancer,there were 31 cases with complete remission,45 cases with partial remission,34 cases with stable,and 11 cases with progression.Conclusion:Ktrans,Kep and ADC are all effective imaging indicators for evaluating concurrent chemoradiotherapy for cervical cancer,and the combined detection of ADC+Ktrans+Kep can help improve the diagnostic efficiency and provide reference for the precise treatment plan of cervical cancer in the elderly.
