Background: The present study was conducted to determine cases of acute appendicitis using MDCT. Materials & Methods: 126 cases of suspected acute appendicitis underwent CT using multi-detector helical CT scanners (MDCT) with intravenous contrast medium starting from diaphragm to the symphysis pubis. Results: Appendiceal diameter found to be 8.7 mm, mild to moderate inflammation was seen in 62, severe inflammation in 50 and free fluid in 14 cases. Sensitivity of CT found to be 94.2%, specificity 81.4%, positive predictive value 88.4% and negative predictive value 90.1%. Conclusion: Maximum cases showed mild to moderate inflammation. CT had high positive predictive value.
