The ultra sonography helps to determine the size of aneurysm. It also helps to identify the free peritoneal fluid. This technique is not invasive and is sensitive. The presence of gas in the bowl and obesity can limit its use. Nearly 100 percent sensitivity is seen with the help of CT scan and it helps to plan the operation.
