With the speed of MDCT acquisition, most young children can be imaged either with sedation or unsedated with feed and wrap. Contrast medium injection should optimally be through a large (20g minimum) cannula with pump injection, but a hand injection may also produce adequate results. Contrast agent bolus timing is important and may be crucial for optimal image quality, vessel delineation and diagnostic confidence. The study was carried out after the approval from the ethics committee. All the patients were explained about the possible adverse effects of contrast medium injection and radiation exposure. Informed signed consent was taken. We can see that in our study MDCT has a very high sensitivity ranging from 80% to 100% and specificity ranging from 80 to 90%. The P value is highly significant.
