Phenobarbital-enhanced hepatobiliary scintigraphy in the diagnosis of biliary atresia: two decades of experience at a tertiary center.
Hepatobiliary scintigraphy is highly sensitive for diagnosing biliary atresia; however, its specificity has varied in the literature from 35% to 97%. ⋯ Phenobarbital-enhanced hepatobiliary scintigraphy is highly accurate in differentiating biliary atresia from other causes of neonatal cholestasis. Biliary atresia is rare in premature infants.

Is procedural sedation with propofol acceptable for complex imaging? A comparison of short vs. prolonged sedations in children.
Concerns exist in the community of non-anesthesiologist sedation providers regarding the appropriateness of prolonged sedations using propofol for outpatient procedures. ⋯ Prolonged outpatient sedations with propofol conducted by appropriately trained non-anesthesiology sedation providers appears effective for imaging procedures with no increase in interventions or increased resource burden compared to short sedations. This information can assist all stakeholders in determining scope of practice and guidelines for moderately longer pediatric sedations with propofol.

Scurvy results from a deficiency of vitamin C and is rarely seen in the United States. We describe the MRI findings of a case of scurvy in an autistic child with food-avoidant behavior. ⋯ To our knowledge, MRI features of scurvy in children in the US have been described in only one case report. This case of scurvy in an autistic child with food-avoidant behavior emphasizes that classic nutritional deficiencies, despite their rarity, must be included in the differential diagnosis of at-risk populations.

Comparative StudyProximal pulmonary vein stenosis detection in pediatric patients: value of multiplanar and 3-D VR imaging evaluation.
One of the important benefits of using multidetector computed tomography (MDCT) is its capability to generate high-quality two-dimensional (2-D) multiplanar (MPR) and three-dimensional (3-D) images from volumetric and isotropic axial CT data. However, to the best of our knowledge, no results have been published on the potential diagnostic role of multiplanar and 3-D volume-rendered (VR) images in detecting pulmonary vein stenosis, a condition in which MDCT has recently assumed a role as the initial noninvasive imaging modality of choice. ⋯ Use of 3-D VR images in the diagnosis of proximal pulmonary vein stenosis in children significantly increases accuracy, confidence level, added diagnostic value and interobserver agreement. Thus, the routine use of this technique should be encouraged despite its increased interpretation time.
