Zusammenfassung
Purpose: In patients suffering from coronary artery disease, determination of myocardial viability by late enhancement (LE) MR imaging (MRI) is of increasing relevance. Despite good results at 1.5T, imaging at 3.0T should provide a significant improvement in contrast (CNR) and signal (SNR) to noise ratio. Aim of this study was to investigate SNR, CNR and image quality of LE-MRI at 3.0T in comparison to 1.5T. Methods: In 15 patients with myocardial infarction cardiac MRI was performed at 1.5T (Magnetom Sonata, Siemens, Germany) and in 15 patients at 3.0T (Magnetom Trio, Siemens, Germany). Myocardial function was…
