[Guideline 'Imaging with ionizing radiation': risks, communication and shielding].

The guideline 'imaging with ionizing radiation' provides information about the risks when using ionizing radiation and the communication thereabout. Because most radiological investigations are performed at one time, the chance of adverse effects, is small, even in children and pregnant women. In case of complex or multiple investigations, the medical physicist can be consulted to estimate the risks.

Differences in Origin and Outcome of Intra-Abdominal Cysts in Male and Female Fetuses.

Objective: To investigate the origin and outcome in a cohort of male and female fetuses with intra-abdominal cysts, in order to provide recommendations on management and to improve prenatal counselling.

Methods: From 2002 to 2016, intra-abdominal cysts were detected by ultrasound in 158 fetuses. Cases with an umbilical vein varix were excluded.

The incidence of negative intraoperative findings after unsuccessful hydrostatic reduction of ileocolic intussusception in children: A retrospective analysis.

Background: There is a lack of studies addressing the occurrence of negative intraoperative findings (that is the absence of intussusception) after an unsuccessful hydrostatic reduction of an ileocolic intussusception. The aim of this study is to determine the incidence of negative intraoperative findings after unsuccessful hydrostatic reduction of ileocolic intussusception.

Methods: We conducted a multicentre retrospective study of all children aged 0-18 years treated for ileocolic intussusception from January 1, 2010 to December 31, 2015 in 9 Dutch hospitals.

High resolution MRI for preoperative work-up of neonates with an anorectal malformation: a direct comparison with distal pressure colostography/fistulography.

Objective: To compare MRI and colostography/fistulography in neonates with anorectal malformations (ARM), using surgery as reference standard.

Methods: Thirty-three neonates (22 boys) with ARM were included. All patients underwent both preoperative high-resolution MRI (without sedation or contrast instillation) and colostography/fistulography.

Predictive value of clinical evaluation in the follow-up of children with a brain tumor.

Background: During follow-up of children with a brain tumor, traditionally surveillance-imaging studies are done in addition to clinical evaluations. The purpose of this study was to determine the role of clinical evaluations by a multidisciplinary team for the detection of recurrent tumor.

Procedure: We retrospectively assessed the predictive value of clinical evaluation, using subsequent neuroimaging as the gold standard.
