Get StartedTests and diagnosis
By Mayo Clinic staffA double uterus is often diagnosed during a routine pelvic exam when the doctor observes a double cervix or feels an abnormally shaped uterus. If the doctor suspects an abnormality, he or she may recommend any of the following tests:
- Magnetic resonance imaging (MRI). This test uses a strong magnetic field to create cross-sectional images of the inside of your body. There's usually no special preparation needed for an MRI; however, the test is conducted in a confined space, and is noisy. It's a good idea to let your doctor know if you're bothered by small spaces or loud noises. He or she may prescribe a mild sedative to make you more comfortable during the test. MRI scans are painless, and there are no known risks from the procedure.
- Ultrasound. This test uses high-frequency sound waves to create images of the inside of your body. To capture the images, a device called a transducer is used. The transducer sends the images to a computer screen. During the test, the transducer is either pressed against your abdominal skin or inserted into your vagina (transvaginal ultrasound). Both types of ultrasound may be done to get the best view of the uterus. To make imaging of the uterus easier through the abdomen, you'll need to drink enough fluid before the exam to fill your bladder. Your doctor will let you know exactly how much to drink and how soon before the exam you need to drink the extra liquids.
- Hysterosalpingography. For this test, a special dye is injected into your uterus through your cervix. This part of the test may be slightly uncomfortable. If you're concerned, ask your doctor to prescribe a mild sedative for the test. As the dye moves through your reproductive organs, X-rays are taken to determine the shape and size of your uterus. These X-rays are displayed instantly on a TV-like monitor.
