Trends in the use of diagnostic imaging can be an important component of tracking ED use and cost. In 2004, more
ED visits included imaging procedures than in 1995 (43% versus 38% of visits, respectively). During 1995--2004, the number
of MRI or CAT scans nearly quadrupled, and the number of ultrasounds more than doubled. The overall number of ED
visits increased by 14%.
