Accelerated free breathing ECG triggered contrast enhanced pulmonary vein magnetic resonance angiography using compressed sensing
BACKGROUND To investigate the feasibility of accelerated electrocardiogram (ECG)-triggered contrast enhanced pulmonary vein magnetic resonance angiography (CE-PV MRA) with isotropic spatial resolution using compressed sensing (CS). METHODS Nineteen patients (59±13 y, 11 M) referred for MR were scanned using the proposed accelerated free breathing ECG-triggered 3D CE-PV MRA sequence (FOV=340×3...
متن کاملNative high-resolution 3D SSFP MR angiography for assessing the thoracic aorta
Methods Seventy-six prospective patients with known or suspicion of thoracic aortic disease underwent MRA at 1.5T using i) native 3D SSFP MRA with ECG and navigator gating and high isotropic spatial resolution (1.3 × 1.3 × 1.3 mm 3) and ii) conventional contrast-enhanced ECG-gated gradient echo 3D MRA (1.3 × 0.8 × 1.8 mm 3). Datasets were compared at 9 aortic levels regarding image quality (sco...
متن کاملNon-contrast-enhanced 4D Intracranial MR Angiography with 4D NATIVE TrueFISP
Introduction: Conventional non-contrast-enhanced (NCE) MRA approaches including time-of-flight and phase contrast methods yield single frame static images or are limited in spatial resolution (typically by reverting to 2D rather than 3D methods) if multiphases ECG triggered acquisitions are used in the case of phase contrast. By administering T1-shortening contrast agents, timeresolved three-di...
متن کاملComparison of native high-resolution 3D and contrast-enhanced MR angiography for assessing the thoracic aorta.
AIMS To omit risks of contrast agent administration, native magnetic resonance angiography (MRA) is desired for assessing the thoracic aorta. The aim was to evaluate a native steady-state free precession (SSFP) three-dimensional (3D) MRA in comparison with contrast-enhanced MRA as the gold standard. METHODS AND RESULTS Seventy-six prospective patients with known or suspicion of thoracic aorti...
متن کاملAccelerated noncontrast-enhanced pulmonary vein MRA with distributed compressed sensing.
PURPOSE To investigate the efficacy of distributed compressed sensing (CS) to accelerate free-breathing, electrocardiogram (ECG)-triggered noncontrast pulmonary vein (PV) magnetic resonance angiography (MRA). MATERIALS AND METHODS Fully sampled ECG-triggered noncontrast PV MRA, using a spatially selective slab inversion preparation sequence, was acquired on seven healthy adult subjects (27 ± ...
