Title: Comparison between CT and ultrasound in diagnosis of pathological classification of appendicitis
Abstract: Objective: To compare the clinical value of diagnosis in pathological classification of appendicitis between CT and ultrasound. Methods: CT noncontrast enhanced scan and ultrasound were performed on 162 patients with clinical doubtful appendicitis. Classified appendicitis compared with the results of operation to calculate correctly diagnostic rate,specificity,sensibility,negative predictive value,positive predictive value,and compared the statistical difference between CT and ultrasound. Results: 156 appendicitis were confirmed by pathology after operation,and the correctly diagnostic rate of CT and ultrasound respectively was 91. 3% and82. 1%,the specificity respectively was 50. 0% and 66. 7%,the sensibility respectively was 94. 9% and 85. 3%,the negative predictive value respectively was 27. 3% and 14. 8%,the positive predictive value respectively was98. 0% and 98. 5%. There was statistical difference between CT and ultrasound. Conclusion: CT and ultrasound have important clinical value in diagnosing different pathologic types and clinical stages of appendicitis,and CT is better than ultrasound in diagnosis of simple and chronicity appendicitis,it can be a complementa examination of negative ultrasonic result and can provide valuable information for clinic.
