Cardiac T1 Mapping and Extracellular Volume (ECV) in clinical practice: a comprehensive review
Cardiovascular Magnetic Resonance is increasingly used to differentiate the aetiology of cardiomyopathies. Late Gadolinium Enhancement (LGE) is the reference standard for non-invasive imaging of myocardial scar and focal fibrosis and is valuable in the differential diagnosis of ischaemic versus non-ischaemic cardiomyopathy. Diffuse fibrosis may go undetected on LGE imaging. Tissue characterisat...
متن کاملAutomated 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 کاملA medical device-grade T1 and ECV phantom for global T1 mapping quality assurance—the T1 Mapping and ECV Standardization in cardiovascular magnetic resonance (T1MES) program
BACKGROUND T1 mapping and extracellular volume (ECV) have the potential to guide patient care and serve as surrogate end-points in clinical trials, but measurements differ between cardiovascular magnetic resonance (CMR) scanners and pulse sequences. To help deliver T1 mapping to global clinical care, we developed a phantom-based quality assurance (QA) system for verification of measurement stab...
متن کاملA T1 and ECV phantom for global T1 mapping quality assurance: The T1 mapping and ECV standardisation in CMR (T1MES) program
Background Myocardial T1 and extracellular volume (ECV) estimates have applications in a range of myocardial diseases. Factors responsible for systematic inaccuracies in T1 mapping are beginning to be known but little is known about its delivery at ‘health-care system’ scale and there is no global quality assurance (QA) system. Agarose phantoms are common in MRI and nickel ions preferred for lo...
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...
