The method of administration depends on the type of imaging being done:
- For Hysterosalpingography: A catheter is inserted through the cervix to inject the iodine-based contrast agent into the uterine cavity and fallopian tubes. - For MRI: The gadolinium-based contrast agent is usually injected into a vein in the arm. - For Ultrasound: Saline or gel-based agents are introduced into the uterine cavity through a catheter.
