Cartilage imaging in adults has been a rich area of research in which MR T2 and T1rho mapping provide complementary information regarding the extracellular matrix, including collagen fibers and glycosaminoglycans, respectively. However, in the pediatric population, there remains a need to obtain normative data for these variables during skeletal maturation. The purpose of this study is to provide complementary information regarding cartilage during skeletal maturation with T2 and T1rho maps. Read More

Diffuse serosal and soft tissue enhancement (SSTE) is a unique pattern of contrast enhancement seen on abdominal radiographs after cardiac catheterization in newborns. While thought to be benign, SSTE can be misdiagnosed as pneumoperitoneum, resulting in unnecessary and potentially invasive diagnostic procedures. The purpose of this study is to describe the incidence of SSTE on abdominal radiograph performed in infants within 2 days of cardiac catheterization and identify clinical features associated with this imaging finding.

Acute kidney injury (AKI) remains a concern in hospitalized children undergoing computed tomography (CT) examinations with intravenous (IV) iodinated contrast material (ICM). Adult studies have shown frequencies of AKI after CT with IV ICM to be similar to propensity score-matched ICM unexposed cohorts. The purpose of this study is to evaluate the association between IV ICM exposure and AKI in hospitalized pediatric patients with stable kidney function undergoing computed tomography (CT). Read More

MR elastography (MRE) is increasingly being used to non-invasively assess diffuse liver disease in children. However, there are limited normal liver stiffness data for MRE in children. The purpose of this study was to determine normal liver stiffness measured by MRE for children and assess for associations with demographic factors, MRI field strength and MRI vendor. Read More
