When is pelvic MRI recommended for bicornuate uterus?

A bicornuate uterus has a deep indentation at the top and two connected uterine cavities. MRI can show the outer shape of the uterus and the internal cavities in detail, helping distinguish this pattern from other uterine differences. It may also show the cervix, vagina, ovaries, and nearby pelvic structures when that information affects planning.

Your clinician may suggest MRI after an ultrasound leaves the uterine shape unclear, before selected surgery, or when pregnancy planning requires a clearer anatomical map. Tell the imaging team about pregnancy, metal implants, kidney problems, or difficulty staying still. Ask how the result will change monitoring or treatment. More information is available in [Pelvic MRI](/treatments/diagnostics-and-imaging/pelvic-mri/).

Arrange medical review for persistent pelvic pain, unusual bleeding, repeated pregnancy loss, or fertility concerns, because these symptoms need an individual assessment rather than an assumption about the uterine shape. Seek urgent care for severe sudden pain, heavy bleeding, fainting, or fever.

Ask what the ultrasound showed, why MRI is being recommended, whether contrast is needed, what alternatives exist, and how the result could affect pregnancy care or a planned procedure.
