Ultrasound assessment of pubertal breast development in girls: intra- and interobserver agreement.
Clinical assessment of pubertal breast development using Tanner staging is subjective. This has led to the introduction of ultrasound (US), aiming for a more objective analysis. However, information regarding its reliability is lacking. ⋯ US using a scale from 0 to 5 is a reliable method to stage the development of glandular breast tissue during puberty in healthy girls. Measurements of glandular depth and diameter were found to be imprecise.

Comparative StudyImplementation of the Amsterdam Pediatric Wrist Rules.
The Amsterdam Pediatric Wrist Rules have been developed and validated to reduce wrist radiographs following wrist trauma in pediatric patients. However, the actual impact should be evaluated in an implementation study. ⋯ Implementing the Amsterdam Pediatric Wrist Rules resulted in a significant reduction in wrist radiographs and time spent at the emergency department. The Amsterdam Pediatric Wrist Rules were able to correctly identify 98% of all clinically relevant distal forearm fractures.

Preoperative sonographic evaluation of the defect size and the diaphragm rim in congenital diaphragmatic hernia - preliminary experience.
Sonographic assessment before congenital diaphragmatic hernia repair has rarely been studied. ⋯ There was good concordance between ultrasound findings and operative findings regarding the size of the defect and presence or absence of the diaphragm rim.

Observational StudyOccult head injury is common in children with concern for physical abuse.
Studies evaluating small patient cohorts have found a high, but variable, rate of occult head injury in children <2 years old with concern for physical abuse. The American College of Radiology (ACR) recommends clinicians have a low threshold to obtain neuroimaging in these patients. ⋯ Our results show a high prevalence of occult head injury in patients <2 years old with suspected physical abuse. Our data support the ACR recommendation that clinicians should have a low threshold to perform neuroimaging in patients <2 years of age.

Optimization of magnetization-prepared rapid gradient echo (MP-RAGE) sequence for neonatal brain MRI.
Sequence optimization in neonates might improve detection sensitivity of abnormalities for a variety of conditions. However this has been historically challenging because tissue properties such as the longitudinal relaxation time and proton density differ significantly between neonates and adults. ⋯ Our in vivo neonatal brain imaging experiments confirmed that both SNR and CNR efficiencies significantly increased with our proposed protocol. Our proposed optimization methodology could be readily extended to other populations (e.g., older children, adults), as well as different organ systems, field strengths and MR sequences.
