Radiology for Residents

Best Practices



The most common definition of EBM is taken from Dr. David Sackett, a pioneer in evidence-based practice. EBM is "the conscientious, explicit and judicious use of current best evidence in making decisions about the care of the individual patient. It means integrating individual clinical expertise with the best available external clinical evidence from systematic research." (Sackett D, 1996).

The indications and limitations of the various radiological investigations in order to understand the most appropriate EBM and cost-effective selection of examinations. This issues will be increasingly important as plans for universal health care develop. They are now politically correct.

A test should be done only if it is expected to influence the management of a patient. A working diagnosis might be considered to be an hypothesis. Ideally, a test should attempt falsification of the hypothesis. It is easy to obtain confirmation multiple times but one negative finding blows the hypoethsi- Black Swan theory. Every genuine test of an hypothesis is an attempt to falsify or to refute it, not confirm it.

The safe and effective use of radiation in medical diagnosis will be discussed as well as the choice of contrast materials (see Radiation Safety).


According to recent research, CT procedure volume is spiking among both radiologists and physicians in other specialties. The increase has raised red flags for government and private insurance payers around the issue of self-referral.
