Abstract
Background Cardiac MRI (cMRI) has evolved as the non-invasive reference standard for accurate and highly reproducible determination of cardiac function and myocardial viability. Thus, cMRI is widespread and increasingly utilized in the clinical practice. The intro duction of open high-field (HFO) MR scanners offers advantages not only for imageguided interventions, examinations of patients with claustrophobia or children, but also for monitoring of critically ill patients. Therefore, the aim of our study was to evaluate unenhanced cMR imaging sequences such as cine balancedsteady-state-free-precession (B-SSFP), T1-weighted (w) turbo spin echo (TSE), T1-w Black-Blood (BB) turbo field echo (TFE), and T2-w BB TSE sequences acquired at an open 1.0T MR scanner with regard to 1) image quality and 2) amount of non-diagnostic (ND) myocardial segments (S) compared to a standard cylindrical 1.5T MR system.

The majority of ND S at both field strengths was detected in the b SA slices [1.0T: T2 TSE 6 segments (b 4/6 segments: 2/4 inferolateral, 1/4 anterolateral, 1/4 inferoseptal; m 2/6 segments: 2/2 inferolateral); 1.5T: T2 TSE 8 segments (b 6/8 segments - 2/6 inferolateral, 3/6 anterolateral, 1/6 inferior; m 2/8 segments - 1/2 inferolateral, 1/2 inferior), T1 TFE 9 segments (b 7/9 segments - 4/7 inferolateral, 1/7 anterolateral, 2/7 inferior; m 2/9 segments: 2/2 anterolateral)]
Standard cardiac MRI sequences at an open 1.0T MR platform offer a high image quality, which is comparable to sequences acquired at a cylindrical 1.5T MR scanner
