Background
Fetal ultrasound has limitations, especially if the patient is obese or in cases with oligohydramnios. Magnetic resonance imaging (MRI) can then be used as a complement, but only few studies have focused on examinations in the second trimester.
Purpose
To validate MRI as a complement to diagnose fetal anomalies in the second trimester....
To evaluate the additional information of second trimester magnetic resonance imaging (MRI) compared with ultrasound in fetuses with identified or suspected non-CNS anomalies and to study the clinical impact of the MRI information on pregnancy management.
Prospective study during 2003-2007. The fetal MRI examination was planned to be performed with...
to evaluate the additional information of second trimester magnetic resonance imaging (MRI) compared to ultrasound in fetuses with identified or suspected central nervous system (CNS) anomalies and to study the clinical impact of the information on pregnancy management.
prospective study during 2004-2007. The fetal MRI examination was planned to be...
To obtain measurements of the normal fetal brain before 24 weeks of gestation (GW), a deadline for medical decisions on fetal viability in a large number of countries.
We retrospectively reviewed 70 normal MR examinations of fetuses aged GW 17 to 23. The fronto-occipital diameter, the cerebral bi-parietal diameter, the transverse cerebellar diamete...
To assess the ascertainment of spina bifida and cleft lip/palate (CLP) in newborns and in fetuses from terminated pregnancies (ToPs) in the Swedish Birth Defects Registry (BDR) and to estimate the true incidences of these two anomalies.
Retrospective register study.
Center for Epidemiology at the Swedish National Board of Health and Welfare, and Up...
To compare antenatal diagnoses with autopsy findings in pregnancies terminated after ultrasound detection of fetal anomalies. A second aim was to study the quality of antenatal fetal diagnosis over time.
Retrospective, multicenter study over two consecutive six-year periods in Uppsala and Stockholm.
Cases were identified through fetal autopsy repor...

... MRI can increase the accuracy of antenatal imaging and hence helping in management of pregnancy. 8 At present, there are multiple studies in literature on contribution of prenatal USG and MR imaging. It is shown that MRI provides additional details to USG in 36% to 57% cases for CNS anomalies. ...
... Fetal MRI is a powerful tool to examine the fetal CNS. 7 The most common postnatal intervention for newborns with DSM is embolization or surgery, 5 which was not needed in our case. Moreover, infants with a prenatally diagnosed DSM ought to be delivered at a hospital with access to pediatric neuroradiology and neurosurgery. ...
... Quantitative and qualitative estimates of fetal brain sizes such as cerebral fronto-occipital diameter, cerebral biparietal diameter, cerebellum transverse diameter, height of vermis, anteroposterior diameter of vermis, extracerebral and intracerebral cerebrospinal fluid were performed in [22,23,24,25,26] previosly. In this study we used a large sample: 8 linear dimensions of the human fetal brain were obtained for 105 fetuses. ...
... Cleft is one of the most common anomalies, affecting 1 in every 500-750 newborns worldwide (Amini, Axelsson, Ollars, & Anneren, 2009;Christensen, Juel, Herskind, & Murray, 2004;Mossey, Little, Munger, Dixon, & Shaw, 2009;Mossey & Modell, 2012). It is a malformation of the face in which cleft lip and/or cleft palate can exist (Christensen et al., 2004;Mossey et al., 2009;Mossey & Castilla, 2001). ...
... A fixed board with a fixed end and adjustable foot, or a metric ruler with calipers, can be used to measure the lengths of the body and feet. Circumference measurements can be made with a string or a piece of tape [34]. Blades, scissors, forceps, and probes of various sizes are necessary for dissecting young infants and fetuses. ...
