Introduction: Introduction: Blunt Abdominal Trauma (BAT) is leading to most causes of death under 45 years of age. Ultrasonography (US) is useful in the evaluation of patients with BAT. Helical CT examination can produce more definitive diagnostic information in about the same time, it takes to perform a complete US examination. CT is accurate in the evaluation of abdominal visceral organ injuries and assessment of the retroperitoneum.
Aim: To assess the role of US and CT in the evaluation of BAT and to compare operative findings or clinical follow-up in conservatively managed patients.
Materials and Methods: This prospective study was conducted in the Department of Radiology from March 2017 to September 2018 on 64 patients with BAT. All patients underwent US and CT abdomen. The patients with haemoperitoneum or abdominal visceral injury or both were considered as positive for intra abdominal injury. The detection of organ injuries and haemoperitoneum on US were correlated with CT findings. Sensitivity, Specificity, PPV, NPV was used to find the correlation of US and CT scan with operative findings.
Results: The overall sensitivity of US in the detection of solid organ injuries was 83.3% and specificity was 87.5%.The PPV was 93.7%, NPV was 70% and accuracy was 84%. The overall sensitivity and specificity in this study with respect to detection of solid organ injuries by CT was 94.7% and 100% respectively. The PPV was 100%, NPV 87.5% and accuracy of this study was 96%.
Conclusion: US may be used as the initial diagnostic modality for suspected BAT. CT is accurate in the detection and quantification of haemoperitoneum and more sensitive in the detection of solid organ injury which is useful in the management of most patients.
