Prospective UTE two-component MRI analysis of graft ligamentization after ACL reconstruction and association with demographic and surgical factors [PDF]

European Radiology Experimental
Background We aimed to evaluate longitudinal changes in ultrashort echo time (UTE) two-component biomarkers reflecting graft ligamentization after anterior cruciate ligament (ACL) reconstruction and to identify associated clinical factors.

Ultrashort echo time and zero echo time MRI at 7T [PDF]

Magnetic Resonance Materials in Physics, Biology and Medicine, 2016
Zero echo time (ZTE) and ultrashort echo time (UTE) pulse sequences for MRI offer unique advantages of being able to detect signal from rapidly decaying short-T2 tissue components. In this paper, we applied 3D ZTE and UTE pulse sequences at 7T to assess differences between these methods.We matched the ZTE and UTE pulse sequences closely in terms of ...

Optimized 3D ultrashort echo time pulmonary MRI [PDF]

Magnetic Resonance in Medicine, 2012
PurposeTo optimize 3D radial ultrashort echo time MRI for high resolution whole‐lung imaging.Methods3D radial ultrashort echo time was implemented on a 3T scanner to investigate the effects of: (1) limited field‐of‐view excitation, (2) variable density readouts, and (3) radial oversampling.

MRI-Based Attenuation Correction for PET/MRI Using Ultrashort Echo Time Sequences [PDF]

Journal of Nuclear Medicine, 2010
One of the challenges in PET/MRI is the derivation of an attenuation map to correct the PET image for attenuation. Different methods have been suggested for deriving the attenuation map from an MR image. Because the low signal intensity of cortical bone on images acquired with conventional MRI sequences makes it difficult to detect this tissue type ...

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 ...

The accuracy of ultrashort echo time MRI sequences for medical additive manufacturing. [PDF]

Dentomaxillofac Radiol, 2016
Additively manufactured bone models, implants and drill guides are becoming increasingly popular amongst maxillofacial surgeons and dentists. To date, such constructs are commonly manufactured using CT technology that induces ionizing radiation. Recently, ultrashort echo time (UTE) MRI sequences have been developed that allow radiation-free imaging of ...
