摘要
子宫肿瘤的发展和转移依赖于肿瘤血管生成。多期动态增强磁共振成像定量分析可根据多种已知的药物动力学模型,采用时间-信号曲线进行分析,模拟出血管(血浆)内外对比剂的分布规律和交换过程,从而定量描述出血流动力学的变化情况,所获得的功能参数能准确无创地评估肿瘤血管生成状态,为子宫肿瘤良恶性鉴别、分期、疗效评估及预后判断提供帮助。
The development and metastasis of uterine tumors depend highly on tumor angiogenesis.Multiphase dynamic contrast-enhanced magnetic resonance imaging can quantitatively describe the hemodynamic changes of uterine tumors based on a variety of tracer kinetic models and time-signal curves and by simulating the distribution of contrast inside and outside the blood vessels.Functional parameters can accurately and noninvasively assess tumor angiogenesis.It provides a non-invasive functional evaluation method for the differential diagnosis,staging,response evaluation,and prognostic prediction of uterine tumors.
