After Nearly A Decade Of Rapid Growth, Use And Complexity Of Imaging Declined, 2008-14.

Imaging is an important cost driver in health care, and its use grew rapidly in the early 2000s. Several studies toward the end of the decade suggested that a leveling off was beginning to occur. In this study we examined more recent data to determine whether the slowdown had continued.

Cost and radiation savings of partial substitution of ultrasound for CT in appendicitis evaluation: a national projection.

Objective: The costs of an ultrasound-CT protocol and a CT-only protocol for an appendicitis evaluation are compared. For the ultrasound-CT protocol, patients with right lower quadrant abdominal pain undergo an ultrasound examination. If it is positive for appendicitis, they are sent directly to surgery, avoiding CT.
