EOS® Versus Spiral CT Technique for Achieving a Pelvimetry in Suites of Obstructed Labor.

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to demonstrate in vivo the concordance of the imagery system EOS and the spiral CT in women having had an obstructed delivery. If this concordance is demonstrated, it would allow the use of this new technique of imagery, to realize a pelvimetry during the pregnancy less irradiating for the mother, and the fetus.

Detailed Description
-----------------
The aim of this study is to demonstrate in vivo the concordance of the imagery system EOS and the spiral CT in women having had an obstructed delivery. If this concordance is demonstrated, it would allow the use of this new technique of imagery, to realize a pelvimetry during the pregnancy less irradiating for the mother, and the fetus. To answer this objective, the study will be a prospective, monocentric, open clinical trial, comparing the radio-pelvimetry realized with EOS technique, to the spiral CT. Measures are performed in the 3 months following the obstructed delivery.

| Experimental: EOS + Spiral CT pelvimetry<br>Women with an indication of pelvimetry will be included in this study. They will be their own control because they will benefit from the two methods of diagnosis : EOS new technique, and spiral CT (usual technique). | Device: EOS<br>* Pelvimetry will be performed with the new EOS technique of diagnosis to measure the diameter of the basin.<br>* Other names: Pelvimetry;Device: Spiral CT pelvimetry<br>* Pelvimetry will be performed with the spiral CT technique. It is the technique usually used.<br>* Other names: Pelvimetry;|

What is the study measuring?

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Diameter of the basin | The aim of this study is to compare the measures of the basins with two different techniques : the usual one spiral CT technique, and the new one : the EOS technique that is less irradiating than the older one. If these two techniques give the same measures, researchers would be able in the future to use the new technique less invasive for the mother and the fetus, as a routine technique. | Day 1 |
