Precision and reproducibility of semi-automated late gadolinium enhancement quantification techniques in patients with hypertrophic cardiomyopathy
Background The presence and extent of hyper-enhancement (HE) on Late Gadolinium Enhancement (LGE) has been associated with adverse events in patients with Hypertrophic Cardiomyopathy (HCM). Signal-threshold techniques are routinely employed for quantification; however, the precision and reproducibility of these versus a gold standard remains uncertain. Full Width Half of Maximum (FWHM) techniqu...
متن کاملAccuracy and reproducibility of semi-automated late gadolinium enhancement quantification techniques in patients with hypertrophic cardiomyopathy
BACKGROUND The presence and extent of late gadolinium enhancement (LGE) has been associated with adverse events in patients with hypertrophic cardiomyopathy (HCM). Signal intensity (SI) threshold techniques are routinely employed for quantification; Full-Width at Half-Maximum (FWHM) techniques are suggested to provide greater reproducibility than Signal Threshold versus Reference Mean (STRM) te...
متن کاملMyocardial fibrosis delineation in late gadolinium enhancement images of Hypertrophic Cardiomyopathy patients using deep learning methods
Introduction: Accurate delineation of myocardial fibrosis in Late Gadolinium Enhancement on Cardiac Magnetic Resonance (LGE-CMR) has a crucial role in the assessment and risk stratification of HCM patients. As this is time-consuming and requires expertise, automation can be essential in accelerating this process. This study aims to use Unet-based deep learning methods to automate the mentioned ...
متن کاملComparison of Semi-automated Late Gadolinium Enhancement Quantification Techniques in Measuring Septal Fibrosis in Patients with Dilated Non-Ischemic Cardiomyopathy
Background Mid-wall striae pattern late gadolinium enhancement (LGE) has been shown to independently predict future outcomes in patients with dilated non-ischemic cardiomyopathy (NICM). Standardized quantification tools are of particular interest for clinical translation of this novel imaging marker. However, signal intensity (SI) based threshold techniques, such as Signal Threshold versus Refe...
