AbstractWith a rapidly growing spectrum, non-specific symptoms and overlapping etiologies, pericardial diseases can represent a real diagnostic challenge. Consequently, multimodality imaging has taken a front seat in the diagnosis and management of these conditions. Cardiac CT offers an excellent anatomical characterization of pericardial thickening, fat stranding and/or presence of calcifications. and is also the preferred modality to assess extra-cardiac structures. Active pericardial inflammation, edema and fibrosis comprise pericardial characterization using CMR and allows for a precise diagnosis, disease staging and patient specific tailoring of therapies. PET scan still occupies a very modest role in the evaluation of pericardial diseases but might help discriminating malignant pericardial effusion and extrapulmonary tuberculous. More than ever, clinicians need to master how these modalities complement each other while avoiding unnecessary cost and to translate this knowledge into a more customized patient's care approach. The aim of this review was to recognize the role of multimodality imaging in the investigation of various pericardial diseases, assess how these modalities can impact the clinical course and treatment of these affections and finally elucidate their role in the patient's prognostication.
