At present, MRI is showing more and more unique advantages in imaging the nervous system and soft tissues. Cervical cancer is a gynecological malignant tumor, which often occurs in the pelvis and is not easy to be detected by patients. MRI can be used for preoperative staging of cervical cancer, checking whether there is any invasion of surrounding tissues and whether there is any lymph node metastasis, and it can play a good role in guiding the patients during the operation, and it can also play a good role in assisting the patients whether to carry out radiotherapy or not for further treatment after the operation. Therefore, cervical cancer should be examined with magnetic resonance to have a better and clear understanding of the disease. If cervical cancer invades the surrounding large blood vessels, it is usually not able to perform surgery, so it has a very clear guiding role for surgery.
