The abdominal radiographic series in children with suspected bowel obstruction--should the second view be abandoned?
To determine whether the addition of a second (horizontal beam) view to the supine abdominal radiograph improves diagnostic accuracy in the diagnosis of paediatric bowel obstruction. ⋯ The value of the routine second radiograph in the accuracy of diagnosis of bowel obstruction is limited, and its use should be restricted to selected cases in which diagnostic uncertainty persists.

Clinical TrialMRI-based blood oxygen saturation measurements in infants and children with congenital heart disease.
Vessel oxygen saturation can be determined with MR oximetry using an in vivo measurement of signal decay (T2) and the calibration curve relating T2 to blood oxygen saturation (%HbO(2)), where: 1/T2=1/T2O+K (1-%HbO(2)/100)(2) and K is a constant parameter which correlates with measured fibrinogen levels. The ability to noninvasively measure %HbO(2) in cardiac chambers and vessels has enormous potential in children with congenital heart disease (CHD). ⋯ Adult values for T2-%HbO(2) calibration can be used to measure blood oxygen saturation in vivo in children with CHD.

Review Case ReportsMesenteric lymphatic malformation associated with small-bowel volvulus - two cases and a review of the literature.
Cystic mesenteric lymphatic malformations are uncommon abdominal masses, which can cause abdominal signs and symptoms for a wide variety of reasons. Symptoms owing to volvulus are uncommon and have not been illustrated previously in the radiology literature. We present two cases to illustrate volvulus as a complication of mesenteric lymphatic malformations and how imaging can aid in the diagnosis of this complication. While uncommon, volvulus should be considered in any child with sonographic findings of an abdominal lymphatic malformation and acute abdominal pain.

Comparative StudyThe development of a pediatric radiology sedation program.
An increase in the number of patients undergoing sedation for imaging procedures has led to many changes in practice over the past 10 years. ⋯ There is improvement in all aspects of patient outcomes with sedation, as a result of several changes in sedation practice.

Comparative StudyIncreased inspiratory pressure for reduction of atelectasis in children anesthetized for CT scan.
Atelectasis is more frequent and more severe in children anesthetized for CT scan than it is in children sedated for CT scan. ⋯ An inspiratory pressure of 30 cm H2O is recommended for children anesthetized for CT scan of the chest.
