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

ConclusionThe patients with AA have significantly higher point PSV and point RI values than those without AA and are especially useful in equivocal patients whose MODs and Alvarado scores are in the diagnostically equivocal ranges of 6 –8 mm and 4–7, respectively, with the point PSV and RI demonstrating negative predictive value 87.5% and 100%.
