Although ultrasound during pregnancy is used extensively, there is little published on adverse fetal effects. We undertook a cohort study including men born in Sweden from 1973 to 1978 who enrolled for military service. We estimated relative risks for being born left-handed according to ultrasound exposure in fetal life using logistic regression analysis. Eligible for the study were 6,858 men born at a hospital that included ultrasound scanning in standard antenatal care (exposed) and 172,537… 

Ultrasound and handedness.

It is found that men who were exposed to ultrasound in utero appear to have a higher probability of becoming lefthanded, and this curious finding raises several important questions.

OC275: Prenatal ultrasound scanning and the risk of schizophrenia and other psychoses

No clear associations between prenatal ultrasound exposure and schizophrenia or other psychoses were found, and men and women born in several of the 7 tertiary level hospitals without ultrasound scanning also had higher risks of schizophrenia compared with those born in other hospitals.

Prenatal Ultrasound Scanning and the Risk of Schizophrenia and Other Psychoses

No clear associations between prenatal ultrasound exposure and schizophrenia or other psychoses were found, and men and women born in several of the 7 tertiary level hospitals without ultrasound scanning also had higher risks of schizophrenia compared with those born in other hospitals.

Prenatal Ultrasound and X-ray - Potentially Adverse Effects on the CNS

The aim with this thesis was to assess the impact of prenatal ultrasound exposure on psychotic illness, childhood brain tumors (CBT) and school achievement, and to evaluate prenatal X-ray exposure

Is Excessive Prenatal Ultrasonography a Risk Factor for Autism? A Literature Review

Excessive PUS usage and ASD development is focused on and enhanced biophysical adverse effects may link the analogous increase in prenatal ultrasonography and autism, and prenatal ultrasound may emerge as a risk factor for autism.

Fetal and umbilical Doppler ultrasound in normal pregnancy.

Routine fetal and umbilical Doppler ultrasound examination in low-risk or unselected populations did not result in increased antenatal, obstetric and neonatal interventions, and no overall differences were detected for substantive short term clinical outcomes such as perinatal mortality.

Fetal and umbilical Doppler ultrasound in normal pregnancy.

Routine fetal and umbilical Doppler ultrasound examination in low-risk or unselected populations did not result in increased antenatal, obstetric and neonatal interventions and there was no available evidence to assess the effect on substantive long-term outcomes such as childhood neurodevelopment.

The study shows that early dating with ultrasound increases the possibilities of clinical judgment at the end of the pregnancy and also indicates that the procedure could contribute to a positive perinatal outcome.

Routine ultrasonography in utero and subsequent handedness and neurological development.

The data suggest a possible association between routine ultrasonography in utero and subsequent non-right handedness, whereas no association with impaired neurological development was found.

It is concluded that no associations between ultrasound exposure in utero and childhood maldevelopment have been proven and there are, however, some issues, such as non‐right handedness and low birth weight after frequent Doppler ultrasound exposures, for which no firm conclusions can yet be drawn.

Early detection in combination with clinical measures was associated with a decrease in the incidence of twins born preterm, and the perinatal mortality rate of twins fell from 6 to 0.6 % after the introduction of this programme.
