Myocardial T1 mapping: a non-invasive alternative to tissue diagnosis?
Endomyocardial biopsy for histological analysis is an important diagnostic tool in non-ischaemic cardiomyopathy. However, endomyocardial biopsy is invasive and associated with some risk, albeit low. The diagnostic yield is also low, because (1)pathology is oftenheterogeneous, (2) current interventional techniques do not permit targeted biopsy, and (3) histological analysis can be difficult. For...
متن کاملNon-invasive measurement of myocardial extracellular volume using T1 mapping as a novel biomarker of diffuse fibrosis in dilated cardiomyopathy
Background Diffuse myocardial fibrosis is frequently observed in histologies of dilated cardiomyopathy (DCM). T1-mapping techniques have the potential to measure fibrosis quantitatively and therefore provide novel cardiac magnetic resonance (CMR) insights into myocardial tissue characterization beyond the presently employed late gadolinium enhanced (LGE) techniques. Fibrosis results in expansio...
متن کاملChanges in remote myocardial tissue after acute myocardial infarction and its relation to cardiac remodeling: A CMR T1 mapping study
OBJECTIVES To characterize the temporal alterations in native T1 and extracellular volume (ECV) of remote myocardium after acute myocardial infarction (AMI), and to explore their relation to left ventricular (LV) remodeling. METHODS Forty-two patients with AMI successfully treated with primary PCI underwent cardiovascular magnetic resonance after 4-6 days and 3 months. Cine imaging, late gado...
متن کاملMyocardial tissue characteriation with native myocardial T1 mapping in SLE patients with chest pain
Background Systemic Lupus Erythematosus (SLE) patients often exhibit signs and symptoms of cardiac ischemia with an overall increased prevalence of coronary artery disease (CAD), coronary microvascular dysfunction and myocarditis in this population. Potentially, these processes may be associated with subclinical changes in myocardial tissue. Elevated native myocardial T1 and extracellular volum...
متن کاملT1 Mapping in Characterizing Myocardial Disease
Cardiovascular magnetic resonance (CMR) is unique in its ability to noninvasively provide insights into cardiac morphology, myocardial architecture, blood flow, tissue perfusion, and function with high diagnostic accuracy and without needing ionizing radiation. In addition, CMR is also well suited to inform on the presence of subclinical disease and to unravel the complex pathophysiology of var...
