Susceptibility-weighted imaging is more reliable than T2*-weighted gradient-recalled echo MRI for detecting microbleeds.
BACKGROUND AND PURPOSE We investigated the sensitivity and reliability of MRI susceptibility-weighted imaging (SWI) compared with routine MRI T2*-weighted gradient-recalled echo (GRE) for cerebral microbleed (CMB) detection. METHODS We used data from a prospective study of cerebral amyloid angiopathy (n=9; mean age, 71±8.3) and healthy non-cerebral amyloid angiopathy controls (n=22; mean age,...
متن کاملComparison of gradient-recalled-echo and T2-weighted spin-echo pulse sequences in intramedullary spinal lesions.
Nineteen consecutive patients with spinal intramedullary lesions were studied on a 1.5-T system to compare the quality of T2-weighted spin-echo and gradient-recalled-echo (GRE) pulse sequences. Direct comparisons were made in the sagittal and/or axial planes. Twenty-four studies were performed in the 19 patients. The gradient echoes were usually performed at 300/14 (TR/TE) with a flip angle of ...
متن کاملVery Fast T2* Imaging by Using Improved Echo-Shifted Gradient-Recalled-Echo (iESGRE)
INTRODUCTION Echo-Shifted Gradient-Recalled-Echo (ESGRE) can be used to rapidly acquire MR images with strong T2* sensitivity [1, 2]. In this approach, excited spins are precessing over multiple TRs before each gradient echo is recalled. Therefore, the effective T2* weighting period in ESGRE is longer than one TR (TE>TR). This property makes it attractive in various clinical applications to sig...
متن کاملT2-Prepared Segmented 3D-Gradient-Echo as Alternative to T2-Weighted TSE for Fast High-Resolution Three-Dimensional Imaging
Introduction: MRI has proven its potential in non-invasive plaque characterization. By combining the information retrieved from MRI images acquired with different image contrasts including T1W, T2W and PDW, the major plaque components can normally be identified. Most studies so far combine multi spin echo (MSE) techniques with multi-slice acquisition for providing coverage of the required regio...
متن کاملGradient Spin Echo (GraSE) imaging for fast myocardial T2 mapping
BACKGROUND Quantitative Cardiovascular Magnetic Resonance (CMR) techniques have gained high interest in CMR research. Myocardial T2 mapping is thought to be helpful in diagnosis of acute myocardial conditions associated with myocardial edema. In this study we aimed to establish a technique for myocardial T2 mapping based on gradient-spin-echo (GraSE) imaging. METHODS The local ethics committe...
