Abstract
In clinical practice, the radiologist interprets an examination by qualitative evaluation and/or based on the value of continuous variables such as lymph node diameter, ejection fraction of the two cardiac ventricles, degree of stenosis of an artery, etc. Moreover, in cases of qualitative assessment, her/his judgment may be given either as a dichotomous variable (yes/no) or as an ordinal variable.
