To study the association between exposure to ultrasound in pregnancy and non‐right handedness in children with available data from randomized trials, data are collected from three randomized trials.

Health professionals’ experiences and views related to obstetric ultrasound in Rwanda and Vietnam

This research presents a novel and scalable approach called “Smart Ultrasound,” which aims to provide real-time information about the construction of the placenta through a non-invasive, 3D ultrasound system.

Diagnostic Ultrasound Safety

Generally diagnostic ultrasound is safe for the fetus and embryo, if thermal and mechanical indices are lower than 1, and ultrasound devices are safe, if it is used under official limitation, e.g. the output intensity is less than SPTA 10 mW/cm2 in Japan.

Higher Prevalence of Left-Handedness in Twins? Not After Controlling Birth Time Confounders

Increased left-handedness among twins, often reported by others, was evident in the data, but only among the older twin cohorts, and that association disappeared after removing effects of perinatal covariates.

Severity of ASD symptoms and their correlation with the presence of copy number variations and exposure to first trimester ultrasound

Exposure to diagnostic ultrasound during early prenatal development of children with specific genetic vulnerabilities found that male children with ASD, copy number variations (CNVs), and exposure to first trimester ultrasound had significantly decreased non‐verbal IQ and increased repetitive behaviors relative to male children without ASD, with CNVs, and no ultrasound.

There is no independently confirmed peer‐reviewed published evidence that a cause‐effect relationship exists between in utero exposure to clinical ultrasound and development of ASDs in childhood.

Safe use of Doppler ultrasound during the 11 to 13 + 6‐week scan: is it possible?

There is a new ISUOG (International Society of Ultrasound in Obstetrics and Gynecology) statement on the use of Doppler ultrasound at 11 to 13 + 6 weeks, and this Opinion discusses some of the issues raised.

Utilization of antenatal ultrasound scan and implications for caesarean section: a cross-sectional study in rural Eastern China

A high use of antenatal ultrasound scan in rural Eastern China is found and is influenced by socio-demographic and clinical factors, which needs to be developed and disseminated to clinicians including physicians, nurses and sonographers.

The Safe Use of Diagnostic Ultrasound in Obstetrics and Gynecology

The diagnostic ultrasound was considered safe after the intensity threshold was known and the output intensity (Ispta) was regulated to be less than 10 mW/cm 2 in diagnostic devices in Japan, and

A meta‐analysis of two follow‐up studies of three randomized controlled trials of routine ultrasonography during pregnancy found an association between ultrasound during pregnancy and subsequent non‐right handedness among children to be stronger among boys.

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.

A systematic review and meta‐analysis to evaluate the safety of human exposure to ultrasonography in pregnancy and the planned International Society of Ultrasound in Obstetrics and Gynecology–World Health Organization multicenter study.

Infant resuscitation is associated with an increased risk of left-handedness.

The results indicate that specific types of birth stress are strongly associated with left hand and foot preference; however, much of the left laterality in non-clinical populations remains unexplained.

Acoustic Output as Measured by Mechanical and Thermal Indices During Routine Obstetric Ultrasound Examinations

The purpose of this study was to quantify the acoustic output of clinical ultrasound instruments, as expressed by the thermal index (TI) and mechanical index (MI), during routine obstetric
