Combined grey scale ultrasound and colour Doppler imaging of the acute
paediatric scrotum provides a non-invasive means of assessing the str
ucture and perfusion of the testis. Colour flow ultrasound is a sensit
ive and specific diagnostic tool for differentiating ischaemic patholo
gy (in which blood flow rate is reduced) from inflammatory disease in
which it is commonly increased. Using this technique the number of unn
ecessary surgical explorations of the scrotum can be reduced. The diff
erential diagnosis of acute testicular pathology and the imaging chara
cteristics of each disorder are described. Close collaboration between
paediatric surgeons and radiologists is required to determine the opt
imal clinical and investigational strategy for each child. (C) 1998 El
