Introduction: Neurovascular Diseases across the Pediatric Age Spectrum.

Pediatric cerebrovascular diseases have distinct clinical presentations, pathophysiology, and management compared to the adult counterparts. This introductory article discusses the imaging techniques and neurovascular conditions unique to each age group from the fetal stages through childhood, including vascular malformations, arteriopathy, and strokes. The article also underscores the importance of genetic factors and the need for a multidisciplinary approach in the diagnosis and treatment of pediatric neurovascular disorders.

Assessing the impact of an orientation week on acclimation to radiology residency.

Purpose: Acclimating residents to radiology residency requires attention to new responsibilities, educational material, and social cohesion. To this end, we instituted a structured orientation week for incoming residents and assessed its impact.

Procedures: During the first weeks of July 2016 and 2017, first year residents attended a five day orientation free of clinical duties, consisting of didactics, hands-on training sessions, and social events.

Mutant IDH1 and thrombosis in gliomas.

Mutant isocitrate dehydrogenase 1 (IDH1) is common in gliomas, and produces D-2-hydroxyglutarate (D-2-HG). The full effects of IDH1 mutations on glioma biology and tumor microenvironment are unknown. We analyzed a discovery cohort of 169 World Health Organization (WHO) grade II-IV gliomas, followed by a validation cohort of 148 cases, for IDH1 mutations, intratumoral microthrombi, and venous thromboemboli (VTE).

What Is the Appropriate Use of Renal Sonography in an Inner-City Population With New-Onset Acute Kidney Injury?

Objectives: We aimed to determine the prevalence of hydronephrosis in patients who underwent renal sonography for new-onset acute kidney injury (AKI) and to identify clinical factors predictive of hydronephrosis. In patients with hydronephrosis, we sought to investigate how routine renal sonography affects patient treatment, including performance of interventional procedures.

Methods: A retrospective chart review identified 274 adults with AKI who underwent renal sonography at an urban teaching hospital from January through July 2011.
