CAE002-b F-18 FDG PET/CT and MRI In the Diagnosis and Management of Cardiac Sarcoidosis Education Exhibits Location: CA Community, Learning Center Participants Richard Anthony R. Coulden MD (Presenter): Nothing to Disclose Emer Sonnex : Nothing to Disclose Hefin Jones FRCR : Nothing to Disclose Indrajeet Das MBBCh, MRCP : Nothing to Disclose Jonathan Thomas Abele MD : Nothing to Disclose TEACHING POINTS In patients with established non-cardiac sarcoidosis, both FDG PET/CT and cardiac MRI can be used to diagnose cardiac involvement. We will learn how and why: 1. FDG PET/CT identifies active disease and can be used in both diagnosis and management. Serial PET allows assessment of response to immunosuppressive treatment. 2. Cardiac MRI identifies myocardial edema and scar. It has proven value in diagnosis but its role in monitoring disease in response to treatment is unclear. 3. Cardiac MRI provides additional value in assessment of ventricular volumes and function and maybe a helpful surrogate in monitoring treatment response. 4. FDG PET/CT and MRI are complementary techniques. TABLE OF CONTENTS/OUTLINE 1. Criteria for clinical diagnosis of cardiac sarcoidosis (Japanese Ministry of Health and Welfare) 2. How to use FDG PET/CT for inflammatory cardiac imaging 3. How to use cardiac MRI for infiltrative cardiomyopathies 4. Relative roles of Cardiac MRI and FDG PET/CT in: a. the imaging diagnosis of cardiac sarcoidosis b. follow-up of disease activity and response to immunosuppressive treatment.

The role of cardiac MRI (CMR) and CT in the diagnosis and differentiation of intra & extra-cardiac shunts 2. To illustrate how CMR can evaluate the functional significance of cardiac shunts 3. To demonstrate the major complications associated with cardiac shunts. TABLE OF CONTENTS/OUTLINE 1.

Demonstrate the CMR and CT features of the common extra-cardiac shunts including: - Patent ductus arteriosus - Partial anomalous pulmonary venous drainage - Scimitar syndrome - Pulmonary arteriovenous malformations - Coronary artery fistulae 3. Demonstrate the common pattern of cardiac chamber enlargement associated with the different types of cardiac shunts 4. Demonstrate how phase contrast MRI sequences can be used to quantify the functional significance of both intra and extra-cardiac shunts 5.

The inferior pyramidal space is the extracardiac fibro-adipose tissue extending between the atrial and ventricular musculatures. Many important structures are concentrated around or inside the inferior pyramidal space. The aims of the presentation are: 1, to demonstrate a series of clinical structural images of the IAS, IVS, each valvular annulus, and inferior pyramidal space reconstructed in combination with the cardiac contour using multidetector computed tomography; and 2, to discuss the clinical implications of findings based on accumulated insights made by pioneers.
