Ultrasound in diagnosis of acute appendicitis

Objective:To explore the diagnostic value and the features of ultrasound in diagnosis of acute appendicitis.Methods:One hundred and nine patients suspected of appendicitis underwent abdominal examination on the right lower quadrant and whole region by low and high frequency ultrasound.The abnormal echo-level masses were measured for the size and examined for both adjacent region and inner echoes for analyzing the imaging features.Results:Of the 109 cases,81 were acute appendicitis and 69 were confirmed by ultrasound(85.2%)and 12 were misdiagnosed.Conclusion:High frequency ultrasound can directly and clearly display the imaging features of acute appendicitis,so it may provide objective evidence for the diagnosis in clinic.
