Biliary Disorders, Anomalies, and Malignancies in Children.

Biliary abnormalities in children are uncommon, and the spectrum of biliary disorders is broader than in adult patients. Unlike in adults, biliary disorders in children are rarely neoplastic and are more commonly rhabdomyosarcoma rather than cholangiocarcinoma. Pediatric biliary disorders may be embryologic or congenital, such as anatomic gallbladder anomalies, anomalous pancreaticobiliary tracts, various cholestatic processes, congenital cystic lesions, or genetic conditions.

Contribution of fetal magnetic resonance imaging in fetuses with congenital heart disease.

Background: Increasing evidence supports an association among congenital heart disease (CHD), structural brain lesions on neuroimaging, and increased risk of neurodevelopmental delay and other structural anomalies. Fetal MRI has been found to be effective in demonstrating fetal structural and developmental abnormalities.

Objective: To determine the contribution of fetal MRI to identifying cardiovascular and non-cardiovascular anomalies in fetuses with CHD compared to prenatal US and fetal echocardiography.

CT Findings of Pediatric Handlebar Injuries.

Direct bicycle handlebar injuries are a significant cause of chest and abdominal trauma and morbidity in the pediatric population. However, these injuries have been underemphasized. While blunt abdominal trauma has been described well, the literature is limited in reviewing trauma imaging specifically related to direct handlebar injuries in the pediatric population.

Magnetic resonance imaging of the pediatric mediastinum.

The mediastinum, the central anatomical space of the thorax, is divided by anatomical landmarks but not by physical boundaries. The mediastinum is a conduit, a space through which cranial nerves, important nerve branches, the sympathetic chain, vascular structures, and visceral structures, the trachea and esophagus pass. This arrangement allows contiguous extension or communication of disease along facial planes and through potential spaces to and from the head and neck or cervical spine, to and from the superior mediastinum, between superior and inferior mediastinal levels, and between inferior mediastinal spaces into the intra- and retroperitoneal spaces.

Cutaneous metastases of infantile choriocarcinoma can mimic infantile hemangioma both clinically and radiographically.

Infantile metastatic choriocarcinoma is a rare tumor of placental origin that can be observed with or without maternal metastases. A single cutaneous mass may be the only clinically observed sign. Reports of imaging findings are scarce given the extreme rarity of the tumor, and the disease can be rapidly fatal in the absence of prompt diagnosis.

T1-weighted imaging of the brain at 3 tesla using a 2-dimensional spoiled gradient echo technique.

Rationale And Objectives: The objective of this study was to evaluate a 2-dimensional spoiled gradient echo (GRE) imaging approach using a very short in-phase TE for routine T1-weighted imaging of the brain at 3 T.

Materials And Methods: Patient examinations were compared from a 3 T magnetic resonance (MR) unit located immediately adjacent to a similarly equipped 1.5 T unit.
