Abstract
OBJECTIVE
In this study, we evaluated the feasibility of using dynamic contrast-enhanced MRI (DCE-MRI) subtracted images as a predictor of a decrease in tumor volume in response to chemoradiotherapy in 13 patients with cervical cancer.
CONCLUSION
This study shows that pretreatment tumor nonenhancing fraction assessed with arterial image subtraction inversely predicts the chemoradiation response in cervical cancer.
摘要
目的
在本研究中，我们评估了使用动态对比增强磁共振成像（DCE-MRI）减影图像作为预测 13 例宫颈癌患者放化疗后肿瘤体积缩小的可行性。
结论
本研究表明，通过动脉图像减影评估的预处理肿瘤无强化部分与宫颈癌的放化疗反应呈负相关。
