Abstract:
Preoperative neoadjuvant therapy is the important part of the comprehensive treatment of locally advanced rectal cancer (cT3-4 or cN+).Accurate assessment of lymph node status before treatment and re-staging of lymph nodes after neoadjuvant therapy are of great significance to clinicians' diagnosis and treatment decisions and prognostic assessment of patients.HR-MRI,DWI,IVIM-DWI,DCE-MRI,and radiomics opened a new wayfor lymph node metastasis assessment accurately.DWI,IVIM,DCE-MRI and other functional MRI imaging can quantitatively and semi-quantitatively analyze lymph nodes from the perspective of diffusion and perfusion,however there is overlap between different parameters,and the research results of different centers are not uniform.Radiomics through high-throughput extracting radiomics features and combining multiple clinical predictors to establish diagnostic and predictive models also shows good predictive potential for rectal cancer lymph node metastasis,but the technology is still in the research stage.Therefore,the combination of multiple imaging technologies and the development of artificial intelligence are the important ways to improve the accuracy of lymph node diagnosis.This article reviews the application of magnetic resonance imaging in lymph node metastasis of rectal cancer and lymph node re-staging after neoadjuvant therapy,in order to provide clinical reference.
