Assessment of Cardiac Sarcoidosis with Advanced Imaging Modalities

Figure 5

Representative images of cardiac MRI and ¹⁸F-FDG PET in a CS patient with complete atrioventricular nodal block. Images of ¹⁸F-FDG PET and cardiac MRI in a 66-year-old woman with pathologically proven CS. (a), (b) Cardiac MRI shows areas of DE and increased T2-weighted signal in the anteroseptal wall of the left ventricle (white and red arrows). (c) ¹⁸F-FDG PET shows focal ¹⁸F-FDG uptake in the anteroseptal of the left ventricle and right ventricle (black arrow). When compared with the ¹⁸F-FDG PET image, the distribution of the positive finding on MRI notably differs. CS: cardiac sarcoidosis, DE: delayed enhancement, MRI: magnetic resonance imaging, T2-WI: T2-weighted image, ¹⁸F-FDG PET: ¹⁸F-fluorodeoxyglucose positron emission tomography.
