Efficacy and safety of deep sedation by non-anesthesiologists for cardiac MRI in children.
Cardiac MRI has become widespread to characterize cardiac lesions in children. No study has examined the role of deep sedation performed by non-anesthesiologists for this investigation. ⋯ There was no difference in the incidence of adverse events or cardiac MRI image adequacy for children receiving general anesthesia by anesthesiologists versus deep sedation by non-anesthesiologists. In summary, this study demonstrates that an appropriately trained sedation provider can provide deep sedation for cardiac MRI without the need for general anesthesia in selected cases.

Three-dimensional skull models as a problem-solving tool in suspected child abuse.
The value of 3-D skull models in evaluation of young children with suspected child abuse is not known. ⋯ Use of 3-D skull models can be a problem-solving tool when there is discordance among the CT reading, subsequent radiographic investigations and clinical evaluation.

Hepatic pathology after Fontan palliation: spectrum of imaging findings.
Patients with congenital heart disease corrected by Fontan palliation have chronic liver congestion that commonly progresses to fibrosis and cirrhosis with resultant complications. ⋯ A high percentage of patients had imaging abnormalities of the liver, chiefly abnormal parenchymal enhancement, which became more apparent as the duration of the Fontan circulation increased. The hypervascular nodules sometimes present had imaging characteristics most closely resembling those of focal nodular hyperplasia. The underlying fibrosis and eventual development of cirrhosis raise the risk of developing hepatocellular carcinoma.

ReviewAdvanced functional thoracic imaging in children: from basic concepts to clinical applications.
The lungs and airways are organs involved in fairly complex body functions, including ventilation, perfusion, respiratory motion and gas exchange. Imaging evaluation of the pediatric thorax is challenging because involuntary, nonsynchronous respiratory motions and cardiac pulsations degrade image quality appreciably. The extraction of clinically useful functional information from noninvasive imaging methods has been realized even in children thanks to recent technical advancements in thoracic imaging modalities. In this article, advanced functional thoracic imaging techniques in children, focusing on CT and MRI, will be explored from basic concepts to clinical applications.
