Third-generation dual-source 70-kVp chest CT angiography with advanced iterative reconstruction in young children: image quality and radiation dose reduction.
Many technical updates have been made in multi-detector CT. ⋯ The third-generation dual-source CT at 70 kVp provided good objective and subjective image quality at lower radiation exposure. ADMIRE improved objective and subjective image quality.

IVC filter retrieval in adolescents: experience in a tertiary pediatric center.
Inferior vena cava (IVC) filters are commonly implanted with the intent to prevent life-threatening pulmonary embolism in at-risk patients with contraindications to anticoagulation. Various studies have reported increases in the rate of venous thromboembolism within the pediatric population. The utility and safety of IVC filters in children has not yet been fully defined. ⋯ In children, IVC filter retrieval can be performed safely but may be challenging, especially in cases of filter tilt or embedding. Adjunctive techniques may increase filter retrieval rates.

ReviewDevelopmental venous anomalies of the brain in children -- imaging spectrum and update.
Developmental venous anomalies (DVAs) are the most common vascular malformation of the brain and are commonly identified on routine imaging of the brain. They are typically considered incidental findings, usually with no clinical significance. ⋯ This pictorial essay explores the suspected embryological origin, associated imaging features, and proposed pathophysiological mechanisms of DVAs in the pediatric population. This paper emphasizes newer physiological imaging data, which suggest that DVA drainage has less physiological flexibility than otherwise normal venous drainage development.

Disk abnormality coexists with any degree of synovial and osseous abnormality in the temporomandibular joints of children with juvenile idiopathic arthritis.
MRI manifestation of temporomandibular joint arthritis is frequently reported in children with juvenile idiopathic arthritis. However, little attention has been paid to temporomandibular joint disk abnormalities. ⋯ Disk abnormalities were frequent. Disk displacement also occurred in joints with early temporomandibular joint arthritis, i.e., with normal bone shape. Other disk abnormalities were found in joints with bone abnormalities. Attention should be paid to disk abnormalities both in early and long-standing temporomandibular joint arthritis in children with juvenile idiopathic arthritis.

Comparative StudyAppendiceal diameter: CT versus sonographic measurements.
Ultrasound and CT are the dominant imaging modalities for assessment of suspected pediatric appendicitis, and the most commonly applied diagnostic criterion for both modalities is appendiceal diameter. The classically described cut-off diameter for the diagnosis of appendicitis is 6 mm when using either imaging modality. ⋯ Measured appendiceal diameter differs between US and CT by 1-2 mm, calling into question use of the same diameter cut-off (6 mm) for both modalities for the diagnosis of appendicitis.
