PURPOSE To plot normal fetal lung volume (FLV) obtained with fast spin-echo magnetic resonance (MR) images against gestational age; to investigate the correlation between lung growth and fetal presentation, sex, and ultrasonographic (US) biometric measurements; and to investigate its potential application in fetuses with thoracoabdominal malformations.

We report a specific sonographic cerebral pattern of cobblestone lissencephaly (CL) that has not been described previously. This pattern was encountered in four index cases and allowed prenatal diagnosis of CL associated with Walker-Warburg syndrome. The pattern included both an outer echogenic band with reduced pericerebral space, corresponding to an(More)
The cerebellum undergoes a protracted development, making it particularly vulnerable to a broad spectrum of developmental events. Acquired destructive and hemorrhagic insults may also occur. The main steps of cerebellar development are reviewed. The normal imaging patterns of the cerebellum in prenatal ultrasound and magnetic resonance imaging (MRI) are(More)
OBJECTIVE To define imaging patterns of unilateral cerebellar hypoplasia (UCH), discuss possible pathophysiological mechanisms and underline the etiology and prognosis associated with these lesions. METHODS In this retrospective study we reviewed the charts of 26 fetuses diagnosed between 2003 and 2011 with UCH, defined by asymmetrical cerebellar(More)
This review focuses on the optimum use of fetal MRI as an additional imaging tool to sonographic data in posterior fossa (PF) abnormalities in the second and third trimesters of gestation. We have chosen three particular situations to demonstrate the value of MRI as a complementary investigation to US: (1) the pattern of increased fluid-filled space of the(More)
OBJECTIVE to test the hypothesis that placental fetal thrombotic vasculopathy (FTV) is associated with obstetric complications and predisposes the child to unfavorable outcomes. METHODS 54 placentas with FTV lesions and 100 placentas without FTV lesions were collected over a 5-year period at the Croix-Rousse Pathology Department. Clinical findings(More)
PURPOSE To evaluate the accuracy of magnetic resonance (MR) cholangiopancreatography in the diagnosis of bile duct obstruction. MATERIALS AND METHODS One hundred twenty-six patients with clinically suspected bile duct obstruction underwent MR cholangiopancreatography with heavily T2-weighted fast spin-echo sequences. Reviewers were blinded to clinical and(More)
