Comparative StudyPost-contrast T1-weighted sequences in pediatric abdominal imaging: comparative analysis of three different sequences and imaging approach.
Post-contrast T1-weighted imaging is an essential component of a comprehensive pediatric abdominopelvic MR examination. However, consistent good image quality is challenging, as respiratory motion in sedated children can substantially degrade the image quality. ⋯ Our preliminary results support the preference of fat-suppressed radial 3-D-GRE as the best post-contrast T1-weighted imaging approach for patients under the age of 5 years, when dynamic imaging is not essential.

Frequency of intrathoracic injuries in children younger than 3 years with rib fractures.
Research documents that among children admitted to trauma intensive care units the number of rib fractures sustained indicates the child's likelihood of having and severity of intrathoracic injury. This has been misused in court to argue that children with multiple rib fractures who lack intrathoracic injury have abnormal bone fragility rather than inflicted injury. ⋯ Abused infants and toddlers have fewer intrathoracic injuries but more rib fractures than accidentally injured peers. This likely reflects different injury mechanics. Lack of intrathoracic injuries in abused children with rib fractures does not imply bone fragility.

The communication of the radiation risk from CT in relation to its clinical benefit in the era of personalized medicine: part 2: benefits versus risk of CT.
In order to personalize the communication of the CT risk, we need to describe the risk in the context of the clinical benefit of CT, which will generally be much higher, provided a CT scan has a well-established clinical indication. However as pediatric radiologists we should be careful not to overstate the benefit of CT, being aware that medico-legal pressures and the realities of health care economics have led to overutilization of the technology. And even though we should not use previously accumulated radiation dose to a child as an argument against conducting a clinically indicated scan (the "sunk-cost" bias), we should consider patients' radiation history in the diagnostic decision process. ⋯ We should anticipate that many patients cannot make informed decisions on their own in this complex matter, and we should offer our guidance while maintaining respect for patient autonomy. Proper documentation of the informed decision process is important for future reference. In concert with our referring physicians, pediatric radiologists are well-equipped to tackle the complexities associated with the communication of CT risk, a task that often falls upon us, and by becoming more involved in the diagnostic decision process we can add value to the health care system.

Case ReportsShrinking lung syndrome complicating pediatric systemic lupus erythematosus.
Systemic lupus erythematosis (SLE) can affect the lungs and pleura, usually manifesting with pleural effusions or diffuse parenchymal disease. A rare manifestation of SLE is shrinking lung syndrome, a severe restrictive respiratory disorder. While pleuropulmonary complications of pediatric SLE are common, shrinking lung syndrome is exceedingly rare in children. ⋯ Her chest radiographs on presentation demonstrated low lung volumes, and CT showed neither pleural nor parenchymal disease. Fluoroscopy demonstrated poor diaphragmatic excursion. While shrinking lung syndrome is described and studied in adults, there is only sparse reference to shrinking lung syndrome in children.
