Background: To evaluate the diagnostic accuracy of the spiral-CT in patients with clinically suspected acute appendicitis.
Methods: Appendiceal spiral-CT was performed in 50 patients (21 women and 29 men) with clinically suspected acute appendicitis. Scans were obtained from the L4 level to the symphysis pubis using 5 mm collimation without i.v., oral, or rectal contrast material. Prospective diagnoses based on CT findings were compared with histopathological results
Results: In our study appendix diameter test sensitivity was 97.56%, specificity was 77.78 %, positive predictive value was 95.27%, negative predictive value was 87.50% and diagnostic accuracy was 94.00%.
Conclusion: The accuracy of computed tomography in diagnosing acute appendicitis was high. The results emphasize the role of computed tomography as an accurate modality in daily routine diagnostics for acute appendicitis in all clinical emergency settings.
