In this era of health care reform and cost containment, major concerns
have been raised regarding inappropriate medical expenditures
and the lack of data to support the necessity of such high levels
of health care spending. It is becoming ever more difficult to justify
diagnostic imaging and other medical procedures with anecdotal evidence,
expert opinion, or experience. Instead, great emphasis has
been placed on the necessity for evidence-based practice to guide
clinical decision-making, especially in light of limited financial resources
and increased public awareness of imaging-related safety concerns,
including risks from radiation and contrast administration.
Evidence-based practice is defined as “integration of the best
research evidence with clinical expertise and patient values.” This
necessitates the balance of scientific evidence, clinical expertise,
and judgment. When strong evidence is available and integrated
in a methodical fashion, practice guidelines can emerge, eventually
shaping new standards of care. However, when strong evidence
is not available, clinical expertise and judgment play a major
role in medical decision-making.
