The uterine protocol uses the same imaging sequences as the routine pelvis protocol. Uterine MRI is performed on patients with suspected uterine masses, uterine anomalies and sometimes for pelvic pain. Since uterine anomalies can be associated with renal anomalies it is useful to start with a large field of view coronal SSFSE locator (using the body coil) to get a quick look at the kidneys. Then switch to a small FOW and higher resolution pelvic array or torso array coil. The uterus is best evaluated on T2 weighted images because of the uterine geometry and importance of showing the endometrium and relationship of any abnormality to the endometrium; it is essential to image the uterus in 3 planes. Start with sagittal T2 and use this as a guide for obtaining images that are axial and coronal to the uterine fundus. An axial T1 weighted sequence is useful as a general pelvic screening sequence for adenopathy or other masses. If endometriosis is suspected image the pelvis with T1 fat saturation images. Met-hemoglobin in endometriomas will be bright on this sequence. When endometrial carcinoma is present, a dynamic Gd FMPSPGR sequence in the sagittal (or axial to uterus) plane can help to delineate the depth of tumor invasion.

1. Why is pelvic MRI requested?
2. Do you have infertility?
3. Do you have pelvic pain? Location?
4. Date of most recent menses? Are you taking any hormones?
5. Any prior imaging (Ultrasound or CT)?
If not Cornell please ask for fax or copies of prior reports.
6. Have you had pelvic surgery? Hysterectomy? Ovaries present or absent?
7. Have you ever had cancer? What type? When was cancer diagnosed?
8. If claustrophobic -- valium 10mg po or axons 1-2 mg po to be taken at time of scanning.
вЂў Pelvic MRI requires a 30 minute slot without Gd, 1 hour if with Gd (ie. mass or cancer).
вЂў Change all clothes; Remove bra if it any metal as it is necessary to obtain one image that includes kidneys.
вЂў If mass or cancer suspected start intravenous line (20 or 22 gauge iv). If iv calibre is small (i.e. 22 gauge) then pre-warm the gadolinium contrast to body temperature to reduce its viscosity.
