Development of a screening MRI for infants at risk for abusive head trauma.
Abusive head trauma (AHT) is an important cause of morbidity in infants. Identifying which well-appearing infants are at risk for AHT and need neuroimaging is challenging, and concern about radiation exposure limits the use of head CT. Availability of an MRI protocol that is highly sensitive for intracranial hemorrhage would allow for AHT screening of well-appearing infants without exposing them to radiation. ⋯ A screening MRI protocol including axial T2, axial GRE and coronal T1-W inversion recovery sequences is highly sensitive for intracranial hemorrhage and may be useful as a screening tool to differentiate well-appearing infants at risk for AHT who should undergo head CT from those who can safely be discharged without head CT. Additional research is needed to evaluate the feasibility of this approach in clinical practice.

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.
