Magnetic resonance diffusion tensor imaging (MRDTI) of the optic nerve and optic radiations at 3T in children with neurofibromatosis type I (NF-1).
Optic pathway glioma (OPG) is a characteristic hallmark of neurofibromatosis type I (NF-I). ⋯ MRDTI can evaluate the optic pathways in children with NF-I. Statistically significant abnormalities were detected in the diffusion tensor metrics of the optic nerves and radiations in children with NF-I compared to age-matched controls.

Pre- and postoperative imaging and interventions for the meso-Rex bypass in children and young adults.
The meso-Rex bypass is a physiological and anatomical bypass procedure for relief of extrahepatic portal vein obstruction and restoration of mesenteric venous return to the liver. Most patients who are candidates for the bypass are children or young adults with portal hypertension and hypersplenism secondary to cavernous transformation of the portal vein. ⋯ Preoperative imaging with US, CT and MR is directed to demonstrate patency and size of the left portal vein and SMV, to define the extent of cavernous transformation and splanchnic collaterals, and to assess for any associated abdominal vascular or solid organ abnormalities. Postoperative imaging is aimed at diagnosing meso-Rex bypass stenosis or occlusion and the interventional management of these complications.

Cardiovascular MRI without sedation or general anesthesia using a feed-and-sleep technique in neonates and infants.
MRI in small children generally necessitates the use of general anesthesia. ⋯ Using this technique, infants younger than 6 months can complete a cardiovascular MRI without the need for sedation or general anesthesia. We advocate the incorporation of this safe and reliable technique into routine clinical practice.

Percutaneous retrieval of intravascular venous foreign bodies in children.
The use of vascular lines both venous and arterial in children has significantly increased in the last decade with the potential risk that an intravascular device may become an intravascular foreign body. Percutaneous retrieval by interventional radiology has become an accepted method of foreign body removal. ⋯ Percutaneous intravascular foreign body retrieval by interventional radiologists is a safe and effective method of retrieving embolized fragments from venous access devices in pediatric patients.

ReviewCompendium of national guidelines for imaging of the pediatric patient.
Diagnostic imaging plays an integral role in diagnosing and managing many pediatric disorders, but there is growing concern in both the medical community and the general public about the long-term health effects of ionizing radiation in children, as well as utilization of imaging evaluation. These concerns, coupled with increasing pressure to reduce national health care spending, underscore the need for an assessment of readily available guidelines, especially evidence-based guidelines, for imaging in children. ⋯ The compendium generated in this study can be used to direct clinical care, inform policy development and improve education of health care personnel. Additionally, the compendium can be used to identify areas of redundancy or deficiency, which may stimulate the reassessment of existing recommendations as well as the creation of new guidelines.
