    Abstract:
    PURPOSE: In this prospective study we aimed to investigate the diagnostic value of ultrasonography (US) in hemodynamically stable children after blunt abdominal trauma (BAT) using computed tomography (CT) as the gold standard. MATERIALS AND METHODS: Between 1997 and 2001, 96 children with BAT were evaluated prospectively. CT was performed first, followed by US. US and CT examinations were independently evaluated by two radiologists for free fluid and organ injury. The sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy of US were assessed regarding CT as the gold standard. RESULTS: Overall 128 organ injuries were determined in 96 patients with CT; however, 20 (15.6%) of them could not be seen with US. Free intraabdominal fluid (FIF) was seen in 82 of 96 patients by CT (85.4%) and eight of them (9.7%) could not be seen by US. We found that sensitivity, specificity, positive predictive value, negative predictive value and overall accuracy of the US for free intra-abdominal fluid were 90.2, 100, 100, 63.6 and 91.7%, respectively. CONCLUSIONS: US for BAT in children is highly accurate and specific. It is highly sensitive in detecting liver, spleen and kidney injuries whereas its sensitivity is moderate for the detection of gastrointestinal tract (GIT) and pancreatic injuries.
