Abstract:
:Rwanda is a country of 12 million people with 41% of its population under the age of 14 years. Despite major improvements in health care since the 1994 genocide, pediatric neuroimaging in Rwanda remains challenging. Prenatal and advanced imaging techniques, such as magnetic resonance imaging (MRI), are not widespread. As a result, many children with neurological diseases present unexpectedly as newborns or are in advanced stages of disease at diagnosis. The goal of this essay is to describe some unique features of the practice of pediatric neuroradiology in Rwanda in 2018.
