Retrospective review shows ultrasound's modest sensitivity and high specificity for appendicitis in adults, highlighting its value in imaging.
Ultrasound demonstrated modest sensitivity but high specificity for diagnosing appendicitis in adults, consistent with international data when inconclusive cases are included. This shows that in the absence of any ultrasound features, appendicitis is unlikely. Alternative findings were twice as common as appendicitis, highlighting the value of ultrasound as a primary imaging modality for the assessment of patients with right lower quadrant pain.
