This study evaluates a concept called 'Teaching the Teachers' and whether it is helpful in disseminating guidelines on the national and international levels. "Teaching the Teachers" involves teaching the guidelines to experts who later teach the same guidelines to other radiologists, trainees, and physicians to assume the teacher's role and disseminate the guidelines and so on.

PRIMARY OBJECTIVES:

I. Evaluate the magnitude of teaching of hepatocellular carcinoma (HCC) diagnostic guidelines after applying "Teaching the Teachers" concept.

II. Assess the effect of "Teaching the Teachers" concept on application of guidelines in clinical practice.
