A comparison between scintigraphy and computed abdominal tomography in blunt liver and spleen injuries in children

Fifty consecutive paediatric patients with objective clinical signs of blunt abdominal trauma underwent both computed abdominal tomography (CT) and liver-spleen scintigraphy (LSS). All were managed non-operatively with no morbidity or mortality. Five splenic and 13 liver injuries were visualised on CT while LSS revealed 9 splenic and 29 liver injuries. Where injury to either organ was detected by both modalities, there was good correlation anatomically and also as to the extent of injury. LSS demonstrated injuries not shown on CT, which appeared to detect only more extensive injuries. We conclude that scintigraphy may be the more sensitive and therefore more appropriate method when blunt injury to the liver and spleen alone is clinically suspected. Abdominal CT remains the early investigation of choice in patients with clinical evidence of haemoperitoneum associated with shock or multiple injuries, particularly when injury to the kidneys as well as to the liver and spleen is suspected or when a concomitant brain scan is indicated.
