Inter-study reproducibility of cardiovascular magnetic resonance myocardial feature tracking
BACKGROUND Cardiovascular magnetic resonance myocardial feature tracking (CMR-FT) is a recently described method of post processing routine cine acquisitions which aims to provide quantitative measurements of circumferentially and radially directed ventricular wall strain. Inter-study reproducibility is important for serial assessments however has not been defined for CMR-FT. METHODS 16 healt...
متن کاملCardiovascular Magnetic Resonance Myocardial Feature Tracking
Abstract—Heart failure–induced cardiovascular morbidity and mortality constitute a major health problem worldwide and result from diverse pathogeneses, including coronary artery disease, nonischemic cardiomyopathies, and arrhythmias. Assessment of cardiovascular performance is important for early diagnosis and accurate management of patients at risk of heart failure. During the past decade, car...
متن کاملReference ranges and reproducibility studies for right heart myocardial deformation by feature tracking cardiovascular magnetic resonance imaging☆
Feature tracking of the right heart on cardiac MRI is a novel and promising technique for the measurement of right heart myocardial strain. We present here the reference ranges for right ventricular longitudinal strain and strain rate, as well as peak strain of the right atrium within a cohort of 100 healthy individuals recruited from the UK. We present data on the reproducibility of these feat...
متن کاملQuantification of left atrial strain and strain rate using cardiovascular magnetic resonance myocardial feature tracking
Background Cardiovascular Magnetic Resonance myocardial feature tracking (CMR-FT) is a quantitative technique tracking tissue voxel motion on standard steady-state free precession (SSFP) cine images to assess ventricular myocardial deformation. The importance of left atrial (LA) deformation assessment is increasingly recognized and can be assessed with echocardiographic speckle tracking. Howeve...
متن کاملInter-vendor reproducibility of left and right ventricular cardiovascular magnetic resonance myocardial feature-tracking
AIM Since cardiovascular magnetic resonance feature-tracking (CMR-FT) has been demonstrated to be of incremental clinical merit we investigated the interchangeability of global left and right ventricular strain parameters between different CMR-FT software solutions. MATERIAL AND METHODS CMR-cine images of 10 patients without significant reduction in LVEF and RVEF and 10 patients with a signif...
