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.

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

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.

Ultrashort Echo Time T1ρ Is Sensitive to Enzymatic Degeneration of Human Menisci [PDF]

Journal of Computer Assisted Tomography, 2015
The aim of the study was to determine whether quantitative ultrashort echo time (UTE) -T1ρ magnetic resonance (MR) measurements are sensitive to proteoglycan degradation in human menisci by trypsin digestion.Conventional and quantitative UTE-T1ρ MR sequences were performed on 4 meniscal samples using a 3T scanner.

Ultrashort Echo Time and Zero Echo Time MRI and Their Applications at High Magnetic Fields: A Literature Survey. [PDF]

Investig Magn Reson Imaging
Ultrashort echo time (UTE) and zero echo time (ZTE) imaging sequences have been developed to detect short T2 relaxation signals emanating from regions or tissues that conventional magnetic resonance imaging (MRI) methods fail to capture. Owing to the high dipole-dipole interactions in solid and semisolid tissues, the signal decay occurs very rapidly ...

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

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

Tendon evaluation with ultrashort Echo Time (UTE) MRI: A Systematic Review. [PDF]

Front Musculoskelet Disord
Tendon disease ranks among the leading reasons patients consult their general practitioners, comprising approximately one-third of musculoskeletal appointments. Magnetic resonance imaging (MRI) is regarded as the gold standard for assessing tendons. Due to their short transverse relaxation time (T2), Tendons show up as a signal void in conventional MRI

Temporal changes in native and late gadolinium enhanced ultrashort echo time magnetic resonance imaging during gynecologic cancer radiation therapy [PDF]

Physics and Imaging in Radiation Oncology
Background and purpose: Radiotherapy (RT) response in gynecologic cancers varies widely and is influenced by several factors. We evaluated whether fibrosis detected with inversion-recovery ultrashort-echo-time (IR-UTE) MRI (magnetic-resonance-imaging ...

Brain short T2 component imaging using double adiabatic inversion recovery prepared ultrashort Echo time (DIR-UTE) sequence [PDF]

NeuroImage
Short T2 components in the brain are uniquely associated with myelin structure, but direct MR imaging is challenging due to their relatively short T2 values and low proton density compared to long T2 water.

Ultrashort Echo Time Magnetic Resonance Morphology of Discovertebral Junction in Chronic Low Back Pain Subjects [PDF]

Tomography
Background: Chronic low back pain (LBP) has been associated with intervertebral disc (IVD) degeneration, but its association with abnormal morphology at the discovertebral junction (DVJ) is unclear.
