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.
