title: Digital subtraction radiography in pediatric cystourethrography.
abstract: Digital subtraction radiography (DSR) was used to evaluate the anatomy and function of the bladder and urethra in 20 children with clinical urinary disturbances deriving from recurrent urinary tract infections. Following image subtraction, a complete study of bladder and urethra morphology and activity before and during voiding was obtained. Furthermore, DSR permitted a reduction in exposure doses given to children compared to conventional film-screen examinations. Results indicate the applicability of this technique for use on a wider scale and suggest its use as an alternative to other diagnostical techniques for the study of this subject.
