Fetal Cardiac Magnetic Resonance (CMR)
Congenital heart disease (CHD) is present in 0.8% of all live births and is therefore one of the most common congenital malformations (Fyler et al., 1980). The spectrum of congenital heart defects is significantly higher in fetuses than in live born infants because of their reduced viability (Tennstedt et al., 1999). The prognosis of congenital heart disease can be poor; almost one third to one...
متن کاملRegistration of 3D fetal neurosonography and MRI☆
We propose a method for registration of 3D fetal brain ultrasound with a reconstructed magnetic resonance fetal brain volume. This method, for the first time, allows the alignment of models of the fetal brain built from magnetic resonance images with 3D fetal brain ultrasound, opening possibilities to develop new, prior information based image analysis methods for 3D fetal neurosonography. The ...
متن کاملFrom 2D to 5D the evolution of fetal neurosonography
Central nervous system (CNS) malformations are the most common defects in the human fetus and affect approximately 0.3-1% of live births1-2. Prenatal detection and accurate definition of CNS malformations are important since these anomalies frequently have a severe prognosis and are often associated with genetic syndromes2. Despite the high incidence of CNS anomalies and the clinical importance...
متن کاملAn introduction to fetal neurosonography using three-dimensional ultrasound
Multiplanar mode: nomenclature The multiplanar mode is probably the most useful tool for assessment of the fetal central nervous system (CNS). With this mode of display, the plane parallel to the acquisition plane or “start” appears in the upper left corner of the screen and is identified with the letter A. The plane perpendicular to A, but parallel to the ultrasound beam, is identified with th...
متن کاملMagnetic resonance methods in fetal neurology.
Fetal magnetic resonance imaging (MRI) has become an established clinical adjunct for the in-vivo evaluation of human brain development. Normal fetal brain maturation can be studied with MRI from the 18th week of gestation to term and relies primarily on T2-weighted sequences. Recently diffusion-weighted sequences have gained importance in the structural assessment of the fetal brain. Diffusion...
