Diagnostic performance of spectral Doppler in acute appendicitis with an equivocal Alvarado score.

Purpose: This study aims to evaluate the added value of duplex Doppler examination to the routinely graded compression grayscale ultrasound (US) for patients with suspected acute appendicitis (AA) in correlation with surgical management outcomes.

Methods: The study lasted from January 2020 to March 2021. Throughout that period, patients who had suspected appendicitis were included with a visible appendix in the grayscale US.
