It is a routine practice for hospital-based practitioners to order radiology studies during the evaluation of sick or injured patients. The information gained from these imaging studies provides crucial information needed to make a diagnosis and guide treatment. As many as 50% of ED patients get a plain X-ray during their visit. It is well known that utilization of CT has greatly increased over the past decade. The end result is millions of patients in the ED and inpatient units who are transported to and from the radiology department.
