We studied CT findings and Interventional Radiology including therapeutic procedures in 43 cases with abdominal blunt trauma, retrospectively. All of parenchymal organ's injuries, and injuries of duodenum & retroperitoneum were correctly diagnosed by CT. In 14 cases with only hemoperitoneum or no positive findings on CT, 4 cases were jejunal perforations, and remaining 10 cases were conservatively treated and relieved. We have to take care that the similar CT findings include the opposite results to need surgery and not.
