High-Contrast Lumbar Spinal Bone Imaging Using a 3D Slab-Selective UTE Sequence

Frontiers in Endocrinology, 2022
Ultra-short echo time (UTE) MRI with post-processing is a promising technique in bone imaging that produces a similar contrast to computed tomography (CT).

Measurement of T1 of the ultrashort T2* components in white matter of the brain at 3T. [PDF]

, 2013
Recent research demonstrates that white matter of the brain contains not only long T2 components, but a minority of ultrashort T2* components. Adiabatic inversion recovery prepared dual echo ultrashort echo time (IR-dUTE) sequences can be used to ...

Ultrashort echo time magnetization transfer (UTE‐MT) imaging of cortical bone [PDF]

NMR in Biomedicine, 2015
Magnetization transfer (MT) imaging is one way to indirectly assess pools of protons with fast transverse relaxation. However, conventional MT imaging sequences are not applicable to short T2 tissues such as cortical bone. Ultrashort echo time (UTE) sequences with TE values as low as 8 µs can detect signals from different water components in cortical ...

An Update in Qualitative Imaging of Bone Using Ultrashort Echo Time Magnetic Resonance

Frontiers in Endocrinology, 2020
Bone is comprised of mineral, collagenous organic matrix, and water. X-ray-based techniques are the standard approach for bone evaluation in clinics, but they are unable to detect the organic matrix and water components in bone.

Whole-Brain Myelin Imaging Using 3D Double-Echo Sliding Inversion Recovery Ultrashort Echo Time (DESIRE UTE) MRI [PDF]

Radiology, 2020
Background Signal contamination from long T2 water is a major challenge in direct imaging of myelin with MRI. Nulling of the unwanted long T2 signals can be achieved with an inversion recovery (IR) preparation pulse to null long T2 white matter within the brain. The remaining ultrashort T2 signal from myelin can be detected with an ultrashort echo time
