Cardiovascular magnetic resonance by non contrast T1-mapping allows assessment of severity of injury in acute myocardial infarction
BACKGROUND Current cardiovascular magnetic resonance (CMR) methods, such as late gadolinium enhancement (LGE) and oedema imaging (T2W) used to depict myocardial ischemia, have limitations. Novel quantitative T1-mapping techniques have the potential to further characterize the components of ischemic injury. In patients with myocardial infarction (MI) we sought to investigate whether state-of the...
متن کاملCharacterization of acute myocardial infarction by pre-contrast T1 mapping
Background Cardiovascular magnetic resonance (CMR) techniques such as late gadolinium enhancement (LGE) and edema imaging (T2W) are used to delineate acute myocardial infarction (MI). However, the use of LGE and T2W to assess reversible injury acutely is challenged by the dynamic changes occurring in the myocardial tissue. T1mapping is a novel technique that provides voxel-wise quantitative inf...
متن کاملTissue injury characterization by pre-contrast T1 mapping post myocardial infarction
Background Myocardial scar and edema can be assessed by late gadolinium enhancement (LGE) and T2W cardiac magnetic resonance (CMR) respectively, but each has important limitations. T1-mapping has emerged as an alternative method to characterize acute ischemic injury and contemporary mapping sequences make this clinically feasible. We assessed the T1 relaxation time in myocardial segments exhibi...
متن کاملFree-breathing post-contrast three-dimensional T1 mapping: Volumetric assessment of myocardial T1 values.
PURPOSE To develop a three-dimensional (3D) free-breathing myocardial T1 mapping sequence for assessment of left ventricle diffuse fibrosis after contrast administration. METHODS In the proposed sequence, multiple 3D inversion recovery images are acquired in an interleaved manner. A mixed prospective/retrospective navigator scheme is used to obtain the 3D Cartesian k-space data with fully sam...
متن کاملPre-contrast T1 mapping for detection of myocardial fibrosis in asymptomatic and symptomatic aortic stenosis
Background Aortic stenosis (AS) leads to diffuse fibrosis in the myocardium which may impair cardiac function. Existing techniques (late gadolinium enhancement [LGE]) are not good at detecting diffuse, as opposed to focal, fibrosis. Pre-contrast T1-mapping may identify changes in the myocardium without the need for exogenous contrast, and our aim was to investigate its ability to detect diffuse...
