Background: To evaluate the accuracy of ultrasonography in diagnosing acute appendicitis. Materials & methods: A total of 100 patients were enrolled. All patients with Alvarado score 4-7 and divided them in two groups: those with Ultrasound study prior to surgery and those without any imaging modalities for diagnosis of AA. The results were analysed using SPSS software. Results: Overall, Sensitivity and specificity of ultrasound in diagnosis of acute appendicitis was 74% and 68.2%, respectively. In 5to16 years old patients, sensitivity and specificity of ultrasound in diagnosis of acute appendicitis was 75% and 65.8% respectively and in ages between17 to 60, sensitivity was 71.2% and specificity was 70.5%. Conclusion: Ultrasound is more useful when the patient is female and the result of sonography is positive.
