Abstract: Image-guided radiotherapy is a promising radiotherapy technology,which can improve the local control rate of cervical cancer patients and reduce the incidence of complications.MRI has high resolution of soft tissue,which is recognized as the gold standard of image-guided brachytherapy for cervical cancer.Although CT soft tissue resolution is lower than MRI,it is easier to identify the applicator,source and source path.In the radiotherapy plan of cervical cancer,the utilization rate of CT is much higher than that of MRI.New imaging technologies,such as PET and MRI,have improved the delineation of target areas in the radiotherapy plans,especially,PET combined with CT and MRI is becoming more and more important in functional imaging.Ultrasound has been replaced by MRI in the initial stage of patients,but it plays an important role in image-guided gynecological implantation and intracavitary brachytherapy.The purpose of this review is to evaluate the application of various imaging techniques in image-guided brachytherapy for cervical cancer.
