Chapter 2: Why is diagnostic imaging necessary?

Correct decisions on whether, when and how to give medical treatment should be based on a best possible diagnosis established by using generally accepted means such as doctors’ clinical judgment, clinical examinations, and some times additional tools such as laboratory examinations and diagnostic imaging.

In general, a majority of diagnostic decisions are based on simple clinical examinations without any need for more sophisticated tools such as laboratory examinations or imaging. Medical doctors as well as other health professionals are at least to some extent trained for such work and all diagnostic work should commence with a clinical evaluation of the patient. Any other tool shall be used only when clinical judgment and examination is not clarifying the situation sufficiently well. When needed, it is also important to use such additional tools after considering their diagnostic potential and possible risks for the specific patient and situation.
