3D inversion recovery ultrashort echo time MRI can detect demyelination in cuprizone-treated mice

Frontiers in Neuroimaging
PurposeTo test the ability of inversion-recovery ultrashort echo time (IR-UTE) MRI to directly detect demyelination in mice using a standard cuprizone mouse model.MethodsNon-aqueous myelin protons have ultrashort T2s and are “invisible” with conventional

A pilot study of short T2* measurements with ultrashort echo time imaging at 0.35 T

BioMedical Engineering OnLine, 2018
Purpose Ultrashort echo time (UTE) sequences play a key role in imaging and quantifying short T2 species. However, almost all of the relevant studies was conducted at relatively high fields. The purpose of this work was to further explore the feasibility

Ultrashort echo time (UTE) MRI of the lung: Assessment of tissue density in the lung parenchyma [PDF]

Magnetic Resonance in Medicine, 2010
AbstractNonuniform disruption of lung architecture is usually assessed by CT, which carries potential radiation risk. Here we report our use of a three‐dimensional ultrashort echo time MR method to image the lungs of normal mice at different positive end‐expiratory pressures in a 3‐T clinical MR system.

Comparison of Signal‐ and Volume‐Based Ventilation‐Weighted Assessment Using 3D FLORET UTE MRI in Patients With Various Pulmonary Disease

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose 3D free‐breathing, proton, contrast‐agent‐free MR methods are increasingly used for pulmonary ventilation‐weighted measurements. The methods are split between: (1) signal‐based, which rely on lung parenchyma signal changes during respiration, and (2) volume‐based that utilize the Jacobian determinant of deformation fields from the ...

Quantitative ultrashort echo time (UTE) MRI of human cortical bone: Correlation with porosity and biomechanical properties [PDF]

Journal of Bone and Mineral Research, 2011
Abstract In this study we describe the use of ultrashort echo time (UTE) magnetic resonance imaging (MRI) to evaluate short and long T2* components as well as the water content of cortical bone. Fourteen human cadaveric distal femur and proximal tibia were sectioned to produce 44 rectangular slabs of cortical bone for quantitative UTE MR

Ultrashort Echo Time and Fast Field Echo Imaging for Spine Bone Imaging with Application in Spondylolysis Evaluation

Computation
Isthmic spondylolysis is characterized by a stress injury to the pars interarticularis bones of the lumbar spines and is often missed by conventional magnetic resonance imaging (MRI), necessitating a computed tomography (CT) for accurate diagnosis.
