Late Gadolinium Enhancemnet imaging of the Left Ventricle in a single breath-hold using multi-slice spiral PSIR imaging at 3T
نویسندگان
چکیده
Background Late gadolinium enhancement (LGE) imaging is the standard method of assessment of myocardial viability. Conventional Cartesian phase sensitive inversion recovery (PSIR) LGE imaging is usually performed as a stack of 2D slices, with each slice being acquired in a single breath-hold [1]. Repeated breath-holding is time consuming and can be difficult or tiring for patients which can lead to mis-registration between slices. Spiral imaging provides highly efficient k-space coverage, allowing for improvements in acquired resolutions or reductions in acquisition durations. We have developed a spiral PSIR LGE sequence with non-Cartesian SENSE to acquire a full stack of 2D slices through the left ventricle within a single breath-hold whilst maintaining spatial resolution.

Free-breathing 3D late gadolinium enhancement imaging of the left ventricle using a stack of spirals at 3T
PURPOSE To develop navigator-gated free-breathing 3D spiral late gadolinium enhancement (LGE) imaging of the left ventricle at 3T and compare it with conventional breath-hold 2D Cartesian imaging. MATERIALS AND METHODS Equivalent slices from 3D spiral and multislice 2D Cartesian acquisitions were compared in 15 subjects in terms of image quality (1, nondiagnostic to 5, excellent), sharpness (...

Background Clinical cardiovascular magnetic resonance imaging (CMR) is routinely performed during multiple breathholds in predefined 2D image orientations. 3D CMR is desirable, since it allows post-acquisition reformatting in any desired imaging plane. However, 3D CMR is hampered by long breath-hold duration, introducing patient discomfort and technical limitations. These limitations can be ove...

Background Late gadolinium enhancement (LGE) imaging is the gold standard for noninvasive evaluation of myocardial scar. In the clinical setting, the standard imaging protocol involves a breath-held segmented inversion-prepared 2D Cartesian acquisition at a single location. This breathhold scan is repeated 10 -14 times to cover the entire left ventricle. Although multislice 2D LGE has shown gre...

BACKGROUND Segmented phase-sensitive inversion recovery (PSIR) cardiovascular magnetic resonance (CMR) sequences are reference standard for non-invasive evaluation of myocardial fibrosis using late gadolinium enhancement (LGE). Several multi-slice LGE sequences have been introduced for faster acquisition in patients with arrhythmia and insufficient breathhold capability. The aim of this study w...

Background In both ischemic (ICM) and non-ischemic (NICM) cardiomyopathy late gadolinium enhancement (LGE) is an important cardiovascular magnetic resonance (CMR) technique. LGE CMR, traditionally performed in 2D during multiple breath-holds (MB), is challenging for vulnerable patients and subject to slice misregistration. Therefore, LGE CMR during free-breathing (FB) is more robust and enables...
