Trial summary

Congenital anomalies are a major public health problem. They affect 2-3% of births, around 20,000 new cases per year in France, of which 15% are cared for in Ile de France. These congenital anomalies are a major cause of morbidity, infant mortality and disability. Read more about this study

About this study

Official title: LUMIERE on the FETUS : A Study on the Added Value of Fetal MRI

Congenital anomalies are a major public health problem. They affect 2-3% of births, around 20,000 new cases per year in France, of which 15% are cared for in Ile de France. These congenital anomalies are a major cause of morbidity, infant mortality and disability. They are also a major cause of death during the infant period (22% of deaths during the first year of life: source CépiDC Inserm 2010). The detection, accurate diagnosis and accurate prognosis, particularly functional, of these congenital anomalies are still difficult in the current monitoring of pregnancy, which is based primarily on ultrasound. The use and development of modern imaging techniques is now essential to enable doctors to better see and better examine the fetus. Alongside ultrasound, Magnetic Resonance Imaging (MRI) is a technique that has undergone significant development in recent years. MRI must allow the effective anatomical and functional evaluation of the main fetal organs and could in particular be interesting in several situations in which it has not yet been sufficiently evaluated and is not yet performed in clinical routine.

Read the detailed description

The inclusion will take place from 16WF to 36WG, within the framework of one of the 4 clinical subgroups of patients envisaged.

The standardized anatomic and functional MRI examination will in all cases last less than 45 minutes and will be based on sequences already used in clinical practice.

Clinical, biological, and ultrasound data will be collected prospectively and used for the usual management of the patient. For the purposes of the study, these data will be secondarily anonymized and analyzed in connection with the MRI data and the perinatal outcome to meet the specific objectives.

The lost-to-follow-up bias will be limited by the simplicity of the proposed perinatal surveillance, which does not differ from the surveillance usually recommended for these pregnancies

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. feasibility of advanced MRI techniques
