Abstract
Trauma is one of the most common causes of death . The abdomen is the most common site of the body to be injuried . Blunt abdominal trauma is the most common type of trauma. Most of blunt abdominal trauma is caused by different types of motor vehicle accidents. Multi-detector CT examination proved to be very sensitive to all types of organ injury. Also it considered the imaging modality of choice to diagnose the solid organ injury and determine the grading of this injury on which the management will be performed either by surgery or by conservative treatment; also it is useful in the follow up of the cases that undergo conservative treatment. Our study was conducted to show the role of MDCT in evaluating the blunt abdominal trauma .This study included 50 patients (36 males & 14 females ),the age ranged between 2 and 70 years old . All patients presented with blunt abdominal trauma and had positive CT findings . All patients were subjected to clinical history & examination followed by CT scan . All patients undergo pre-contrast scan followed by post-contrast scan using IV contrast material . Delayed scan was done for selected cases with renal injury for evaluation of collecting system involvement .
Our study showed that the liver is the most commonly injured organ in children & young adults while the spleen is the most commonly injured one in adults , followed by kidney, while the pancreas is the least organ to be injured .
Summary & Conclusion

Most of renal injuries in our study were of minor types (grade I &II each representing 37.5%) , so managed conservatively . Isolated pancreatic injury was extremely rare . It is usually occur as apackage injury (associated with other organs injuries ) . Multi-detector CT play an important role in detection of active hemmorage which is an emergency state that need speed and accuracy to be dealed with . In our study 6% of cases were shown to having active hemorrhage . We conclude that MDCT is the gold standard method for evaluation of blunt abdominal trauma as it play an important role not only in detection of organ injury , but also in the grading of this injury on which the management will be performed . Also it is important in the follow up of cases which undergo conservative treatment . In addition MDCT proved to be highly sensitive in detection of active hemorrhage which is a life threatening condition. So CT examination (in particular MDCT) with IV contrast should be done whenever possible to all patients with blunt abdominal trauma even if the US examination revealed normal criteria specially in cases with warning clinical signs (decreased BP & increased pulse ). we recommend to perform precontrast scan followed by post-contrast scan to all patients for evaluation of hematoma and exclude infarction . Also we recommend that delayed scan should be done to patients with renal injury for assessment of collecting system involvement.

In addition , we recommend to do bone window for all patients for assessment of any associated fractures . Also coronal and saggital reconstruction images are of great values to assess the extension of any lesion .
