The uterus is part of the pelvic cavity, and it should be noted that the pelvic MRI should be performed one week after menstruation because the uterus has a special physiological cycle. Patients should be reminded that they should not carry a contraceptive ring during the pelvic MRI because the ring often contains copper, which will affect the homogeneity of the magnetic field and produce artifacts, which will easily affect the diagnosis and make it difficult to identify whether the artifacts are caused by the ring or whether there is a real lesion inside the uterus. With the improvement of medical technology, there are many minimally invasive surgical methods and patients’ requirements for their own physiological integrity. There are many minimally invasive procedures, such as cervical surgery that will preserve part of the patient’s uterus and preserve the patient’s reproductive function. The diagnostic process must be very precise, and the MRI will describe in detail how deep the lesion penetrates into the myometrium or where it is located in the endometrium, and what kind of surgical treatment can be used for the patient, so that the patient gets the least trauma and the most benefit. Therefore, in recent years, MRI of the uterus is very important. Many patients with endometrial cancer, cervical cancer and fibroids have to use MRI of the uterus for diagnosis, differentiation and staging, and to clarify whether they are suitable for minimally invasive surgical treatment, so this is an emerging test.
