Pelvimetry by computed tomography (CT pelvimetry)
CT Pelvimetry (Late Pregnancy) in Casablanca
CT pelvimetry is a reduced-dose CT scan that measures the dimensions of the mother's bony pelvis in late pregnancy. These measurements help the obstetrician judge whether a vaginal delivery can be considered, or whether a planned cesarean section seems more prudent. The exam does not study the baby itself: the baby's size and position are assessed by ultrasound. It is performed only on your obstetrician's prescription.
Duration, report and equipment
Duration
The exam is very short: generally 5 to 10 minutes in the room, with the image acquisition itself taking only a few seconds.
Report turnaround
Report within 24 hours. In an emergency, during opening hours, the report is handed over immediately.
Equipment
GE Revolution
When is this exam needed?
- Baby in breech position (buttocks or feet down), when a vaginal delivery is being discussed.
- Suspected narrow pelvis, for example in case of short stature.
- History of a pelvic fracture or a hip malformation.
- History of a difficult delivery or a cesarean section, depending on the obstetrician's opinion.
How the exam is done
You are welcomed and then positioned lying on your back on the CT table, with a cushion if needed. In late pregnancy, this position can make you feel faint, because the weight of the uterus presses on a large vein in the abdomen: tell us immediately if you feel unwell, and you will be tilted slightly onto your left side.
The machine takes one or two localization images of the pelvis, then a few targeted slices, with deliberately low settings. No injection is given and you feel nothing. You simply need to stay still and breathe calmly during the few seconds of image acquisition. The radiologist then measures the different diameters of the pelvis on the images.
Preparation
- Have the exam on the date set by your obstetrician, most often in the last weeks of pregnancy.
- Bring your pregnancy follow-up file and your latest ultrasound scans.
- Choose clothing without metal parts around the pelvis, or a loose dress.
- If you have regular contractions, fluid leakage or bleeding, go to the maternity ward rather than the center.
Fasting
No fasting is needed. Drink normally.
Contrast injection
CT pelvimetry is always performed without contrast agent: no needle is used.
Contraindications and precautions
- Exam reserved for situations where the obstetrician considers the measurements useful: it is never performed without a prescription.
- Signs of early labor, bleeding or reduced baby movements: go to the maternity ward first.
- Feeling faint when lying on your back during previous exams: tell us as soon as you arrive.
- Other X-ray exams performed during the pregnancy: mention them to the radiologist.
Documents to bring
- Prescription from the obstetrician
- Pregnancy follow-up file or record book
- Reports of the latest obstetric ultrasound scans
- Report of a previous delivery or cesarean section, if applicable
- Insurance or mutual insurance fund card

Frequently asked questions
Are X-rays dangerous for my baby?
CT pelvimetry uses a reduced-dose protocol, limited to the pelvis, and it is performed in late pregnancy, when the baby is fully formed. Your obstetrician prescribes it only if the measurements are useful for the delivery decision. If you have any concerns, talk about them with your obstetrician or with the radiologist before the exam.
Does the result alone decide how I will give birth?
No. The measurements of the pelvis are one element among others. The obstetrician compares them with the baby's position and estimated weight, your obstetric history and the course of the pregnancy. The obstetrician then explains the proposed approach to you.
Why have this exam so late in pregnancy?
In late pregnancy, the baby's position has generally stabilized, especially in a breech presentation, and the question of how to deliver arises in practical terms. This timing also takes into account the fact that exposure to X-rays should be avoided in early pregnancy.
Can someone come with me?
Yes, someone can accompany you to the reception desk. They do not stay in the room during the image acquisition, so as not to be exposed to X-rays unnecessarily. The team helps you get onto and off the table, which is welcome in late pregnancy.
