Distribution of late gadolinium enhancement in various types of cardiomyopathies: Significance in differential diagnosis, clinical features and prognosis

Figure 5 Representative short axis cine- cardiac magnetic resonance (A), late gadolinium enhancement-cardiac magnetic resonance (B), ¹⁸F-fluorodeoxyglucose-positron emission computed tomography (C), and positron emission computed tomography (D) images in a 57-year-old male patient with systemic sarcoidosis. The diagnosis of sarcoidosis was made with liver biopsy. Cine-CMR images shows normal LV size and contraction (LVEDV: 119 mL, LVEF: 73%), but LGE-CMR reveals patchy and striated LGE in anterior wall and inter-ventricular septum (white arrows). The patient was negative for cardiac involvement of sarcoidosis according to the guideline of Japanese Ministry of Health and Welfare. However, FDG-PET and PET-CT images demonstrate hot spot in postero-lateral wall of LV, indicative of active inflammatory change (black and red arrows). FDG-PET: ¹⁸F-fluorodeoxyglucose-positron emission computed tomography; LGE: Late gadolinium enhancement; LV: Left ventricular; LGE-CMR: Late gadolinium enhancement-cardiac magnetic resonance.
