Automated inline extracellular volume (ECV) mapping
Background Quantitative extracellular volume (ECV) estimates based on T1 mapping have potential for characterizing cardiomyopathies with diffuse fibrosis and edema [1,2]. An unsupervised approach for generating pixel-wise ECV maps was recently introduced [3]. In this work we extend the algorithms to include saturation recoverybased T1 mapping and present an inline implementation of these method...
متن کاملMyocardial T1 and extracellular volume fraction mapping at 3 tesla
BACKGROUND To compare 11 heartbeat (HB) and 17 HB modified lock locker inversion recovery (MOLLI) pulse sequence at 3T and to establish preliminary reference values for myocardial T1 and the extracellular volume fraction (ECV). METHODS Both phantoms and normal volunteers were scanned at 3T using 11 HB and 17 HB MOLLI sequence with the following parameters: spatial resolution = 1.75 × 1.75 × 1...
متن کاملPrevalence of increased myocardial extracellular volume fraction in dilated cardiomyopathy
Background Extracellular volume fraction cardiac magnetic resonance (ECV-CMR) enables quantitative myocardial tissue characterization. Increased myocardial ECV is correlated to myocardial fibrosis, inversely related to the left ventricle ejection fraction (LVEF), and an independent predictor of mortality. Dilated cardiomyopathy (DCM) is characterized by decreased LVEF and increased LV end-diast...
متن کاملRegional left ventricular myocardial T1 and velocity mapping: elevated extracellular volume fraction is associated with altered myocardial velocities
Background Non-ischemic cardiomyopathy (NICM) is a common cause of left ventricular (LV) dysfunction and may be associated with myocardial fibrosis. Global LV systolic function may underestimate the impact of fibrosis on myocardial function and is insensitive to regional abnormalities in myocardial motion. Advances in cardiac MRI have enabled quantification of myocardial fibrosis through the ca...
متن کاملMyocardial extracellular volume fraction and myocardial fibrosis by cmr in patients with severe aortic stenosis
Background Severe aortic stenosis (AS) induces diffuse interstitial myocardial fibrosis (MF). CMR late gadolinium enhancement (LGE) technique is useful to detect focal MF. The amount of MF is associated with worse long-term prognosis after aortic valve replacement surgery (AVR). Measurements of T1 relaxation times before and after gadolinium administration allow determination of myocardial extr...
