Comparative StudySelective CT for PET/CT: dose reduction in Langerhans cell histiocytosis.
In Langerhans cell histiocytosis (LCH), FDG PET demonstrates active disease in bone. Other imaging modalities show the effects of bone destruction by LCH. ⋯ Substantial reduction in effective dose is possible using selective CT techniques for FDG PET/CT.

Transient flow response after femoral artery catheterization for diagnostic neuroangiography in infants and children: Doppler US assessment of the ipsilateral femoral artery.
Hemodynamic changes in the distal arteries during transfemoral catheterization in children have not been documented. ⋯ Changes in the spectral waveforms of superficial femoral arteries frequently occur in children during transfemoral cerebral angiography (13/27, 48%). Significant arterial flow disturbance was noted on Doppler US in children with a common femoral artery <1 mm larger than the femoral sheath diameter.

Chloral hydrate in pediatric magnetic resonance imaging: evaluation of a 10-year sedation experience administered by radiologists.
Chloral hydrate is a sedative that has been used for magnetic resonance imaging (MRI). ⋯ Chloral hydrate is an appropriate sedation option for pediatric patients in MRI services when strict patient selection criteria are met. The use of a reduced dose does not affect the effectiveness of sedation. The lack of data regarding the presence of transient oxygen desaturation, the time to induce sedation and the exact duration of sedation are limitations of this study.
