Computed tomography (CT) has become the preferred modality for imaging children with suspected kidney stones, even though national guidelines recommend the use of ultrasound, according to results from a study published online in Pediatrics.
Study researchers, using a cross-sectional analysis of national insurance data, found that more than half of children with kidney stones underwent initial CT imaging, while fewer than one-quarter underwent ultrasound, Medscape Medical News reports.
Imaging protocols developed by the American Urological Association last year and the European Society Pediatric Radiology in 2009 recommend that CT be used only when an initial ultrasound is nondiagnostic. Article
