Ultrasound evaluation for patients with suspected appendicitis saves money by decreasing utilization of CT while reducing patient radiation exposure and related long-term effects, according to a study recently published in the American Journal of Roentgenology. While CT is valuable for cases where diagnosis is uncertain, the authors note that ultrasound as the first-line diagnostic can eliminate the need for some of those scans. "If we can do an ultrasound first, we can avoid enough CTs to gain significant cost savings and avoid radiation exposure," said study author Laurence Parker.
