T1 Mapping by CMR Imaging

T1 Mapping by CMR Imaging

Fro Ge He Sie infl La Ph Ma OBJECTIVES The purpose of this study was to prospectively investigate the diagnostic and prognostic impact of cardiac magnetic resonance (CMR) T1 mapping and validate it against left ventricular biopsies. BACKGROUND Extracellular volume (ECV) expansion is a key feature of heart failure. CMR T1 mapping has been developed as a noninvasive technique to estimate ECV; how...

T1 mapping in daily CMR practice

Background Dual T1 mapping allows for a comprehensive assessment of myocardial tissue by combining detection of edema in the native scan and quantification of extracellular volume (ECV) after administration of Gadolinium. Recent studies proved the diagnostic value of T1 mapping in different pathologies; the aim of this study was, to evaluate the practicability and robustness of T1 mapping in as...

T1 mapping by CMR in patients with arrhythmic cardiomyopathy

Background Traditionally, late gadolinium enhancement (LGE) helps effectively detect focal fibrosis in cardiomyopathy. If patients have diffuse fibrosis, LGE could not provide enough objective evaluation of the severity of the disease. Arrhythmic cardiomyopathy (ACM) is a clinical entity which corresponds to all myocardial changes induced by chronic tachycardia. For ACM patients, myocardial fib...

Advances in parametric mapping with CMR imaging.

Cardiac magnetic resonance imaging (CMR) is well established and considered the gold standard for assessing myocardial volumes and function, and for quantifying myocardial fibrosis in both ischemic and nonischemic heart disease. Recent developments in CMR imaging techniques are enabling clinically-feasible rapid parametric mapping of myocardial perfusion and magnetic relaxation properties (T1, ...
