The session is aimed at clarifying the role of radiological imaging diagnostics and the contribution of nuclear medicine methods in the diagnosis and differential diagnosis of inflammatory conditions. Obviously the number of these conditions is endless, therefore we decided to focus on two areas where both specialties contribute to the evaluation of the clinical situation: vascular graft infections and inflammation and inflammatory bowel diseases. Speakers from both disciplines reveal the most up-to-date information, including the role of hybrid imaging techniques in order to give a comprehensive overview of the morphological and functional diagnostic algorithm and define the most appropriate examination protocols. The panel discussion following the presentations will provide the opportunity to further deepen consensual knowledge leading to an integrated diagnostic approach to these clinically challenging conditions. Session Objectives: 1. To understand the importance of functional and morphological imaging evaluation of inflammatory conditions in certain inflammatory conditions. 2. To evaluate the specific role and the proper diagnostic algorithm of nuclear medicine and radiological techniques. 3. To highlight potential avenues of future development for functional and morphological imaging in the diagnostics of these conditions.
