2° Obstetric and foetal ultrasound for diagnostic purposes carried out because of a proven risk of foetal anomaly, including obstetric and foetal ultrasound limited to a part of the anatomy or biometry of the foetus and its appendages.
IV – Ultrasound equipment intended for carrying out imaging examinations in support of prenatal diagnosis must meet the essential safety requirements applicable to them and be used under conditions that do not compromise the safety and health of patients or any other person. The Minister for Health shall, where necessary, set the conditions for the use of this equipment in an order issued after consultation with the French National Agency for the Safety of Medicines and Health Products.

VI -The obstetric and foetal ultrasound scans provided for in III may only be performed by doctors and midwives with skills recognised by a diploma attesting to this or an equivalent qualification authorising them to perform these procedures in a Member State of the European Union or party to the Agreement on the European Economic Area. An order issued by the Minister for Health specifies the qualifications required.
