Comparison of optimized soft‐tissue suppression schemes for ultrashort echo time MRI [PDF]

Magnetic Resonance in Medicine, 2011
AbstractUltrashort echo time (UTE) imaging with soft‐tissue suppression reveals short‐T2 components (typically hundreds of microseconds to milliseconds) ordinarily not captured or obscured by long‐T2 tissue signals on the order of tens of milliseconds or longer.

MRI Visualization of Whole Brain Macro- and Microvascular Remodeling in a Rat Model of Ischemic Stroke: A Pilot Study [PDF]

, 2020
Using superparamagnetic iron oxide nanoparticles (SPION) as a single contrast agent, we investigated dual contrast cerebrovascular magnetic resonance imaging (MRI) for simultaneously monitoring macro- and microvasculature and their association with ...

Simple and robust saturation‐based slice selection for ultrashort echo time MRI [PDF]

Magnetic Resonance in Medicine, 2014
PurposeTo present a new method for localizing signal within a two‐dimensional (2D) slice suitable for ultrashort echo time (UTE) imaging, called saturation‐based UTE (sat‐UTE). The new method digitally subtracts two acquisitions that are nonselectively excited with and without selective saturation of the slice of interest.MethodsSat‐UTE was compared ...

In vivo UTE-MRI reveals positive effects of raloxifene on skeletal bound water in skeletally mature beagle dogs [PDF]

, 2015
Raloxifene positively affects mechanical properties of the bone matrix in part through modification of skeletal bound water. The goal of this study was to determine if raloxifene induced alterations in skeletal hydration could be measured in vivo using ...

Quantifying temperature-dependent T1 changes in cortical bone using ultrashort echo-time MRI. [PDF]

Magn Reson Med, 2015
To demonstrate the feasibility of using ultrashort echo-time MRI to quantify T1 changes in cortical bone due to heating.Variable flip-angle T1 mapping combined with 3D ultrashort echo-time imaging was used to measure T1 in cortical bone. A calibration experiment was performed to detect T1 changes with temperature in ex vivo cortical bone samples from a

Ultrashort echo time (UTE) MRI for the assessment of caries lesions

Dentomaxillofacial Radiology, 2013
Direct in vivo MRI of dental hard tissues by applying ultrashort echo time (UTE) MRI techniques has recently been reported. The objective of the presented study is to clinically evaluate the applicability of UTE MRI for the identification of caries lesions.40 randomly selected patients (mean age 41 ± 15 years) were enrolled in this study.

Applicator visualization using ultrashort echo time MRI for high-dose-rate endorectal brachytherapy [PDF]

Brachytherapy, 2020
The individual channels in an endorectal applicator for high-dose-rate endorectal brachytherapy are not visible on standard MRI sequences. The aim of this study was to test whether an ultrashort echo time (UTE) MRI sequence could be used to visualize the individual channels to enable MR-only treatment planning for rectal cancer.We used a radial three ...
