Red flags include suspected epidural abscess or hematoma presenting with acute pain, but no neurological symptoms (urgent imaging is required); suspected cancer; suspected infection; cauda equina syndrome; severe or progressive neurologic deficit; and suspected compression fracture. In patients with suspected uncomplicated herniated disc or spinal stenosis, imaging is only indicated after at least a six-week trial of conservative management and if symptoms are severe enough that surgery is being considered.

Although CT is accurate in the evaluation of suspected appendicitis in the pediatric population, ultrasound is nearly as good in experienced hands. Since ultrasound will reduce radiation exposure, ultrasound is the preferred initial imaging examination in children. If the results of the ultrasound exam are equivocal, it may be followed by CT. This approach is cost-effective, reduces potential radiation risks and has excellent accuracy, with reported sensitivity and specificity of 94 percent.

The Canadian Association of Radiologists (CAR) established its Choosing Wisely Canada Top 5 recommendations by initially soliciting expert opinion from physician leaders within its Board of Directors. A working group was then formed to further identify common clinical scenarios in which imaging may be misused and should be reconsidered. The working group included CAR leaders in the areas of medical imaging appropriateness and access. The list was narrowed down based on the highest potential for improvement, representing a broad range of tests and the availability of strong guidelines. The first three recommendations had previously been researched, submitted and adopted for another appropriateness initiative underway in Canada in 2013. That process included obtaining stakeholder support from a range of colleagues including technologists, sonographers, nuclear medicine physicians, family physicians and physicists. Two additional recommendations were added using similar criteria, including a comprehensive literature search undertaken through the Canadian Agency for Drugs and Technologies in Health. The full list of proposed recommendations was then vetted by stakeholder organizations, such as provincial radiology organizations and the full CAR membership. Item 4 was adapted with permission from the Five Things Physicians and Patients Should Question, © 2012 American College of Radiology.
