Abstract:
The incidence of rectal cancer gradually increased in our country in recent years.Preoperative imaging methods are used to accurately display the lesions of rectal cancer,providing accurate quantitative diagnostic information,therefore being important to formulate reasonable and individualized therapy clinically.Intra-voxel incoherent motion (IVIM) is a multi parameter imaging technology.IVIM can provide the diffusion and perfusion information from the molecular level.Theoretically,the microstructure information of internal rectal cancer cell density and the vascular density,and the tumor cell metabolism can be displayed quantitatively with IVIM imaging,which can reflect the heterogeneity of the tumor and its degree during different periods.The application status and the future development of IVIM technique in management of rectal cancer were reviewed in this article.
