Randomized Controlled Trial Multicenter Study Comparative StudyComparison of SSFP and IR GRE techniques for measurement of total myocardial mass-influence of applied contrast dosage and implication for relative infarct size assessment.
To compare total left ventricular mass assessment using steady state free precession (SSFP) and inversion recovery fast gradient echo (IR GRE) imaging and further to assess the influence of contrast dosage on mass by IR GRE and its implications on relative infarct size assessment with both methods. ⋯ Total LV mass calculations using SSFP and IR GRE techniques are interchangeable when using appropriate contrast media, such as gadoversetamide. Late gadolinium enhancement results in good blood myocardial CNR. Hence, for relative infarct size assessment either method for calculation of total myocardial mass can be used.

Multicenter StudyReproducibility of free-breathing cardiovascular magnetic resonance coronary angiography.
Contemporary free-breathing non contrast enhanced cardiovascular magnetic resonance angiography (CMRA) was qualitatively and quantitatively evaluated to ascertain the reproducibility of the method for coronary artery luminal dimension measurements. ⋯ In a 2-center study, we demonstrate that free-breathing 3D SSFP CMRA can visualize long continuous segments of coronary vessels with highly reproducible measurements of luminal diameter.
