Characterization of the ultra-short echo time magnetic resonance (UTE MR) collagen signal associated with myocardial fibrosis
Background The homogeneous distribution of collagen in diffuse myocardial fibrosis renders the disease unsuitable for imaging using late gadolinium enhancement (LGE) [1]. More recently, the estimation of extracellular volume from T1 maps involving gadolinium agents has shown promise; however, these methods are not specific to collagen and are governed by gadolinium kinetics [2]. The diagnosis o...
متن کاملUltrashort Echo Time (UTE) MR Lung Imaging with Respiratory Motion Compensation
Introduction: Conventional gradient-echo based magnetic resonance imaging of lung parenchyma suffers from poor signal-to-noise ratios due to low proton density and short T2* caused by susceptibility gradients between airways and tissue. In addition, respiratory and cardiac motions seriously degrade the achievable image quality. Ultra-short echo time (UTE) MRI has recently gained renewed attenti...
متن کاملViability of Oxygen-enhanced Ventilation Imaging of the Lungs Using Ultra-short Echo Time MRI
PURPOSE To assess the viability of oxygen-enhanced ventilation images using ultra-short echo time magnetic resonance imaging (UTE-MRI). METHODS We evaluated the oxygen enhancement of the pulmonary T2*, and pulmonary signals in each TE (0.2, 0.8, 1.4, 2.0 ms) in 21 nonsmokers. RESULTS The oxygen enhancement of pulmonary signals was the most significant (32%) at the 0.2 ms TE, the second in t...
متن کاملUltra-short echo time cardiovascular magnetic resonance of atherosclerotic carotid plaque
BACKGROUND Multi-contrast weighted cardiovascular magnetic resonance (CMR) allows detailed plaque characterisation and assessment of plaque vulnerability. The aim of this preliminary study was to show the potential of Ultra-short Echo Time (UTE) subtraction MR in detecting calcification. METHODS 14 ex-vivo human carotid arteries were scanned using CMR and CT, prior to histological slide prepa...
متن کاملVentilation/Perfusion MR imaging of the lung using T1-weighted ultra-short echo time (UTE) imaging: animal experiment in a 3 T clinical MRI system
Introduction: Ultra-short TE (UTE) imaging in conjunction with projection acquisition of free induction decay (FID) can reduce TE to less than 100 μs thus minimizing signal decay caused by short transverse relaxation time (T2/T2*). This allows detection of endogenous MR signal of the lung parenchyma compared to a conventional short echo image sequence (1). Using an UTE sequence, we have demonst...
