简要总结
To evaluate the role of duplex doppler in diagnosis of appendicitis compared to CT
详细描述
Acute appendicitis (AA) is the most common acute abdominal condition worldwide [1]
Thus far, the clinical diagnosis of (AA) remains a challenge to emergency physicians and surgeons both in the pediatric and adult populations, as the symptoms are often atypical and overlapped with various other diseases[2],[3].
The accurate diagnosis of AA depends on both clinical presentations and imaging techniques.
To date, US and computed tomography (CT) remain the most common used diagnostic imaging, and CT is considered the gold standard technique to evaluate patients with suspected AA, because of its high sensitivity and specificity [2],[3]. While the associated radiation exposure remains a concern, especially, among children, the elderly and pregnant women, as radiation protection is of major importance [2],[3],[5],[6].
Over recent years, research on various aspects of US imaging in the diagnosis of (AA) has gained major importance due to its radiation protection, broad availability and cost-effectiveness [6].
