BACKGROUND: Cardiac involvement is an important prognostic factor in patients with sarcoidosis. In this study, we evaluated the usefulness of gadolinium-DTPA (diethylene triamine pentaacetic acid)-enhanced magnetic resonance imaging (Gd-MRI) for diagnosing cardiac sarcoidosis and evaluating the effects of steroid therapy. METHODS: Sixteen patients with sarcoidosis diagnosed by histology or by Japanese Ministry of Health and Welfare criteria for cardiac sarcoidosis underwent Gd-MRI with a 1.5-Tesla superconducting magnet system using a T1-weighted spin-echo sequence. RESULTS: Gd-MRI showed localized enhancement of signal intensity, indicating interstitial edema, in the left ventricle in 8 of the 16 patients. Two patients with enhancement also had thinning of the left ventricular septal wall. After 1 month of prednisolone therapy (60 mg every other day or 30 to 40 mg every day), the localized high-intensity signals were markedly diminished in all 8 patients. CONCLUSIONS: Images of the heart obtained by Gd-MRI may reflect active inflammation with interstitial edema in patients with sarcoidosis. Gd-MRI may be a useful noninvasive method for early detection of cardiac sarcoidosis and for evaluating the effects of steroid therapy.
