The authors present in this chapter an overview on evaluation of medical image compression. The different methodologies used in the literature are presented. Subjective evaluation uses some a priori knowledge such as the judgment of experts or the ability to realize a correct diagnosis. Objective evaluation generally takes into account the value of metrics: the PSNR is an example of such a criterion. The goal of hybrid evaluation is to realize a reliable judgment while having a simple computation. The authors discuss on the benefits and drawbacks of these approaches. The European Project called OTELO in which they were involved, gives feedback on ultrasound image compression.

Receiver Operating Characteristic (ROC):ROC curves provides tools to analysis the behavior of models, algorithms or human judgments.Subjective Evaluation: It is a quantitative or a qualitative evaluation involving experts or some a priori knowledge.
