Intra-cardiac distribution of late gadolinium enhancement in cardiac sarcoidosis and dilated cardiomyopathy

Figure 1 Non-invasive cardiac imaging in a 61-year-old male patient with cardiac involvement of systemic sarcoidosis. LE-CMR (A) shows diffuse LE in the subepicardium (RV side) and subendocardium (LV side) of basal to apical ventricular septum and patchy LE in the midwall of posterior LV (white arrows); Corresponding FDG-PET (B) demonstrates focal uptake in basal and apical ventricular septum and posterior LV wall (black arrows); ^99mTc-sestamibi SPECT (C) exhibits a defect only in ventricular septum (black arrows). CMR: Cardiac magnetic resonance; FDG-PET: ¹⁸F-fluorodeoxyglucose-positron emission computed tomography; LE: Late gadolinium enhancement; LV/RV: Left and right ventricles; SPECT: Single photon emission computed tomography.
