Ultrasound First, Not CT, For Diagnosing Suspected Acute Appendicitis

Color Doppler ultrasound, not CT, should be the first imaging examination for adult patients with suspected acute appendicitis, a new study emphasizes.

The study of 420 medical records found that sonography correctly denied acute appendicitis in 303 of 312 adult patients, meaning it had a 97% specificity rate, said Diana Gaitini, MD, of Rambam Health Care Campus in Haifa, Israel. "When the patient does not have acute appendicitis, the negative result of the color Doppler ultrasound examination is highly confident," she said. On the other hand, ultrasound's sensitivity rate was 74%, meaning it missed the diagnosis in 23 of 89 patients, Dr. Gaitini said. Ultrasound was inconclusive in 17 patients.
