【摘要】：近年来,我国直肠癌发病率逐年升高,术前应用影像学方法较为准确地显示直肠癌病变并提供定量分析信息,对临床合理制定个性化的治疗方案至关重要。通过体素内不相干运动(IVIM)的多参数成像技术,可从分子水平反映组织的弥散和灌注情况,理论上可定量显示直肠癌内部细胞密度、微血管密度的结构学信息及肿瘤细胞代谢的功能学过程,从而反映肿瘤不同时期的异质性及其程度。本文就IVIM技术在直肠癌方面的应用现状及未来发展趋势进行综述。
[Abstract]:In recent years, the incidence of rectal cancer in China has been increasing year by year. It is very important for clinical rational establishment of individualized treatment plan to apply imaging method to accurately display rectal cancer lesions and provide quantitative analysis information. The multiparameter imaging technique of voxel incoherent motion IVIMA can reflect the diffusion and perfusion of tissues at the molecular level and can quantitatively display the density of cells in rectal cancer theoretically. The structural information of microvessel density and the functional process of tumor cell metabolism reflect the heterogeneity and degree of tumor at different stages. This article reviews the application and future development of IVIM technology in rectal cancer.
