    Description: CMR T2-mapping is a promising tool for characterizing myocardial edema. We applied T2-mapping in volunteers to compare two mapping sequences and to assess feasibility, reproducibility and spatial homogeneity.

    Description: Cardiovascular magnetic resonance (CMR) imaging can precisely quantify cardiac size and function, but moreover depict tissue changes that are associated with various forms of myocardial inflammation. Thereby, CMR can often detect myocardial inflammation before contractility is obviously impaired. Various CMR techniques to assess aspects of inflammation including T2-weighted imaging, and early- and late-contrast enhanced T1-weighted imaging, are reviewed regarding technical challenges and clinical usefulness. In this article we discuss the available evidence regarding clinical application of CMR in different forms of myocardial inflammation.

    Description: According to the wavefront-phenomenon myocardial infarction scar should have a larger extent on the subendocardial than the subepicardial surface. This is important for differentiating ischemic from nonischemic lesions in late gadolinium enhancement (LGE) images.

    Description: In a large series of 216 consecutive patients CMR could noninvasively differentiate various types of bicuspid aortic valve (BAV) morphology. BAV type was related to the frequency of stenosis but not to the frequency of aortic dilatation.

    Description: Abstract Background The orifice area of mitral bioprostheses provides important information regarding their hemodynamic performance. It is usually calculated by transthoracic echocardiography (TTE), however, accurate and reproducible determination may be challenging. Cardiovascular magnetic resonance (CMR) has been proven as an accurate alternative for assessing aortic bioprostheses. However, whether CMR can be similarly applied for bioprostheses in the mitral position, particularly in the presence of frequently coincident arrhythmias, is unclear. The aim of the study is to test the feasibility of CMR to evaluate the orifice area of mitral bioprostheses. Methods CMR planimetry was performed in 18 consecutive patients with mitral bioprostheses (n = 13 Hancock®, n = 4 Labcore®, n = 1 Perimount®; mean time since implantation 4.5 ± 3.9 years) in an imaging plane perpendicular to the transprosthetic flow using steady-state free-precession cine imaging under breath-hold conditions on a 1.5T MR system. CMR results were compared with pressure half-time derived orifice areas obtained by TTE. Results Six subjects were in sinus rhythm, 11 in atrial fibrillation, and 1 exhibited frequent ventricular extrasystoles. CMR image quality was rated as good in 10, moderate in 6, and significantly impaired in 2 subjects. In one prosthetic type (Perimount®), strong stent artifacts occurred. Orifice areas by CMR (mean 2.1 ± 0.3 cm2) and TTE (mean 2.1 ± 0.3 cm2) correlated significantly (r = 0.94; p 〈 0.001). Bland-Altman analysis showed a 95% confidence interval from -0.16 to 0.28 cm2 (mean difference 0.06 ± 0.11 cm2; range -0.1 to 0.3 cm2). Intra- and inter-observer variabilities of CMR planimetry were 4.5 ± 2.9% and 7.9 ± 5.2%. Conclusions The assessment of mitral bioprostheses using CMR is feasible even in those with arrhythmias, providing orifice areas with close agreement to echocardiography and low observer dependency. Larger samples with a greater variety of prosthetic types and more cases of prosthetic dysfunction are required to confirm these preliminary results.

    Description: We applied T2 mapping in 72 volunteers compared to 15 patients with myocardial edema. T2 of myocardial edema was 70 ms, whereas normal myocardium had a T2 of 55ms. However, female volunteers showed a wider range of myocardial T2 with overlap into values considered abnormal.
