Summary

The purpose of this clinical study is to test the performance of low radiation dose abdominal CT combined with low dose contrast media for the diagnosis of acute appendicitis in young patients. The main questions to be answered are: 1. Can low-dose contrast media paired with low-dose radiation CT of the abdomen provide acceptable diagnostic accuracy in acute appendicitis? 2. How much radiation dose can be saved by using low radiation dose abdominal CT in combination with low dose contrast media?
