Extracellular volume fraction measurement correlates with lymphocyte abundance in thymic epithelial tumors [PDF]

Cancer Imaging, 2020
Background Recent advance in tissue characterization with parametric mapping imaging has the potential to be a novel biomarker for histopathologic correlation with thymic epithelial tumors (TETs).

Extracellular volume fraction mapping in the myocardium, part 2: initial clinical experience [PDF]

Journal of Cardiovascular Magnetic Resonance, 2012
Background Diffuse myocardial fibrosis, and to a lesser extent global myocardial edema, are important processes in heart disease which are difficult to assess or quantify with cardiovascular magnetic resonance (CMR) using conventional late gadolinium ...

Synthetic extracellular volume fraction without hematocrit sampling for hepatic applications [PDF]

Abdominal Radiology, 2021
Abstract Purpose Calculation of extracellular volume fraction (ECV) currently receives increasing interest as a potential biomarker for non-invasive assessment of liver fibrosis. ECV calculation requires hematocrit (Hct) sampling, which might be difficult to obtain in a high-throughput radiology department.

Prevalence of increased myocardial extracellular volume fraction in dilated cardiomyopathy [PDF]

Journal of Cardiovascular Magnetic Resonance, 2013
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.

Mapping Myocardial Salvage Index by Extracellular Volume Fraction [PDF]

Circulation: Cardiovascular Imaging, 2017
In ST-segment–elevation myocardial infarction (STEMI) patients treated by primary percutaneous coronary intervention (PPCI), the myocardial salvage index (MSI) provides a more sensitive measure for assessing the efficacy of novel cardioprotective therapies, than an absolute reduction in myocardial infarct (MI) size.

Left ventricular extracellular volume fraction and atrioventricular interaction in hypertension [PDF]

European Radiology, 2018
Left atrial enlargement (LAE) predicts cardiovascular morbidity and mortality. Impaired LA function also confers poor prognosis. This study aimed to determine whether left ventricular (LV) interstitial fibrosis is associated with LAE and LA impairment in systemic hypertension.Following informed written consent, a prospective observational study of 86 ...

Synthetic Myocardial Extracellular Volume Fraction

JACC: Cardiovascular Imaging, 2017
Myocardial extracellular volume fraction (ECV) assessed by cardiac magnetic resonance (CMR) estimates the proportion of myocardial extracellular space relative to its cellular component. Conventionally, ECV calculation requires knowledge of the patient’s hematocrit (Hct). Treibel et al. [(1)][1]

Automatic software for extracellular volume fraction mapping in the myocardium [PDF]

Journal of Cardiovascular Magnetic Resonance, 2015
Background CMR is a useful tool for myocardial tissue characterization and to assess fibrosis and edema non-invasively. The estimation of extracellular volume fraction (ECV) is emerging as accurate biomarkers in many cardiac diseases associated with diffuse myocardial fibrosis. In this work, we present our automatic tool for ECV map creation.
