Effect of a split-flow physician in triage model on abdominal CT ordering rate and yield.
The objective of this study was to compare the rate and clinical yield of computed tomography (CT) imaging between patients presenting with abdominal pain initially seen by a physician in triage (PIT) versus those seen only by physicians working in the main emergency department (ED). For patients with abdominal pain, the investigators found no significant differences in rates of CT ordering or CT yield for patients seen in a PIT vs. traditional models.

Clinician perspectives on considering radiation exposure to patients when ordering imaging tests: a qualitative study.
The authors examined outpatient clinician attitudes towards considering radiation exposure when ordering CT scans and clinician reactions to displaying radiation exposure information for CT scans at clinician electronic order entry. They found that displaying clinically relevant radiation exposure information at order entry may improve clinician knowledge and inform patient-clinician discussions regarding risks and benefits of imaging.

In-office imaging capabilities among procedure-based specialty practices.
The authors sought to determine whether arrangements tailored to fit Stark law spur utilization. They found that the availability of in-office advanced imaging is associated with increased imaging use.

Nationwide emergency department imaging practices for pediatric urolithiasis: room for improvement.
The researchers describe the national use of computed tomography (CT) versus ultrasound imaging for pediatric patients seen at emergency departments (EDs) for suspected urolithiasis (SU) during the period 2006-2010. Use of CT was much higher than use of ultrasound, although it dropped off after 2007. Lowest CT use was seen at EDs that care for more children.
