Abstract:
Objective:To recognize the diagnostic value of emergency unenhanced CT without oral contrast material in the diagnosis of infrequent abdomen injury.Methods:990 patients with abdomen symptoms underwent plain scan using 16-row spiral CT without oral contrast material;their CT pictures were noted to find adrenal gland,pancreas,and hollow viscus injure.All cases underwent laparotomy or follow-up CT visit.The initial CT results were compared with the operative and follow-up outcome.Results:In the 990 patients with abdomen symptoms,there were 12 cases of adrenal gland injuries;17 cases of pancreas injuries,and 26 cases of hollow viscus injuries.Compared with operative and follow-up outcome,there was 0 false-negative and 0 false-positive in adrenal gland injury and the sensitivity was 100%;there were 2 false-negatives and 3 false-positives in pancreas injury and the sensitivity was 83.3%;there were 6 false-negatives and 7 false-positives in hollow visceral injury and the sensitivity was 76%.Conclusion:16-slice spiral CT has high diagnostic value in acute infrequent abdomen injury,The diagonostic sensitivity is higher to adrenal gland injury,but relatively lower to hollow viscus injury.
