AbstractAbstract
[en] Fetal MRI is clinically performed to evaluate the brain in cases where an abnormality is detected by prenatal sonography. These most commonly include ventriculomegaly, abnormalities of the corpus callosum, and abnormalities of the posterior fossa. Fetal MRI is also increasingly performed to evaluate fetuses who have normal brain findings on prenatal sonogram but who are at increased risk for neurodevelopmental abnormalities, such as complicated monochorionic twin pregnancies. This paper will briefly discuss the common clinical conditions imaged by fetal MRI as well as recent advances in fetal MRI research. (orig.)

AbstractAbstract
[en] Fetal endocardial fibroelastosis (EFE) has been diagnosed by antenatal ultrasonography in the past few years. A typical case of isolated endocardial fibroelastosis is illustrated here, in a fetus of 22 weeks of gestational age exposed to maternal organophosphorus poisoning at 20 weeks. No other structural cardiac or other systemic anomalies were detected in this fetus. The abnormal fetal echocardiographic features mimicking endocardial fibroelastosis completely regressed after 14 weeks and a normal full-term baby was delivered. Postnatal echocardiogram showed normal cardiac parameters. The diagnostic features mimicking EFE following maternal organophosphorus poisoning at 20 weeks of gestational age and the subsequent complete reversal of these changes after 14 weeks of diagnosis are reported for the first time in the literature

AbstractAbstract
[en] Conjoined twinning is a very rare occurrence with no genetic predisposition. Twisting of conjoined twins around the axis of their connecting tissue bridge, close to the third trimester, has not been previously reported. We describe a unique case of in utero twisting of conjoined omphalopagus twins who survived without any adverse effects. Fetal US and fetal MRI played a vital role in the diagnosis and perinatal management of these twins. (orig.)

AbstractAbstract
[en] Three new cases of Desbuquois syndrome in two brothers and a sporadic male, all of whom died in early infancy, are presented to emphasize the high rate (33 %) of lethality in this variable, but serious skeletal dysplasia. Including the three presented patients and 10 of the 36 cases in the literature who died, most did so between birth and 7 months and from respiratory-related problems. Neonatal and infancy survivors should be monitored closely, particularly relative to their pulmonary status. (orig.)

AbstractAbstract
[en] Sonographic determination of fetal gender was attempted prospectively in most pregnancies of more than 26 weeks. We studied 193 cases of pregnancies with ultrasound for recent 9 months from June 1984 to February 1985 at department of radiology, Soonchunhyang university, Soonchunhyang Chunan hospital, and analysed ultrasonographic finding of fetal gender. The results were as follows; 1. Overall accuracy rate for fetal gender is 90%. 2. Accuracy rate for male fetus is 97.8%. 3. Accuracy rate for female fetus is 88.2%

AbstractAbstract
[en] Objective. Fetal heart rate variability (HRV) is widely used for monitoring fetal developmental disturbances. Only expensive fetal magnetocardiography (fMCG) allows the precise recording of the individual fetal heart beat intervals uncovering also highly frequent vagal modulation. In contrast, transabdominal fetal electrocardiography (fECG) suffers from noise overlaying the fetal cardiac signal. Cardiotocography (CTG) is the clinical method of choice, however, based on Doppler ultrasound, improper to resolve single beats concisely. The present work addresses the transferability of established electrophysiological HRV indices to CTG recordings during the fetal maturation period of 20–40 weeks of gestation (WGA). Approach. We compared (a) HRV indices obtained from fMCG, CTG and fECG of short-term amplitude fluctuations (sAMPs) and long-term amplitude fluctuations (lAMPs) and complexity, and (b) their diagnostic value for identifying maturational age, fetal growth restriction (FGR) and small for gestational age (SGA). We used the functional brain age score (fABAS) and categories of long- and short-term regulation and complexity. Main results. Integrating all substudies, we found: (a) indices related to long-term regulation, and with modified meaning and values of short-term regulation and sympathovagal balance (SVB) according to electrophysiological HRV standards can be obtained from CTG. (b) Models using HRV indices calculated from CTG allow the identification of maturational age and discriminate FGR from controls with almost similar precision as electrophysiological means. (c) A modified set of HRV parameters containing short- and long-term regulation and long-term/short-term ratio appeared to be most suitable to describe autonomic developmental state when CTG data is used. Significance. Whereas the predominantly vagally modulated beat-to-beat precise high frequencies of HRV are not assessable from CTG, we identified relevant related HRV indices and categories for CTG recordings with diagnostic potential. They require further evaluation and confirmation with respect to any issues of fetal developmental and perinatal problems in subsequent studies. This methodology significantly extends the measures of established CTG devices. Novelty and significance HRV indices provide predestinated diagnostic markers of autonomic control in fetuses. However, the established CTG does not provide the temporal precision of electrophysiological recordings. Beat-to-beat related, mainly vagally modulated behavior is not exactly represented in CTG. However, a set of CTG-specific HRV indices that are mainly comparable to established electrophysiological HRV parameters obtained by magnetocardiography or electrocardiography provided almost similar predictive value for fetal maturational age and were helpful in characterizing FGR. These results require validation in the monitoring of further fetal developmental disturbances. We recommend a corresponding extension of CTG methodology. (paper)
