title: [Renal eco Doppler in pediatrics].
abstract: During the last few years, technological improvements in Doppler sonography have transformed a primitive imaging technique in a sophisticated diagnostic tool. The complexity of the physical concept which is at the basis of technique, the different ways to use it and the results depending on either the equipment quality or the operator's skill, have produced confusion and doubts about the real value of Doppler sonography for assessing diseases of the kidney and urinary tract in infants and children. The purpose of this article is to review the basic concepts concerning the physics of Doppler effect, to describe the principal Doppler sonography instrumentation (continuous-wave, pulsed-wave, color Doppler and power Doppler equipment) and to discuss the diagnostic applications of renal Doppler in paediatric imaging.
