Improved Liver R2* Mapping by Averaging Decay Curves. [PDF]

, 2017
Liver R2* mapping is often degraded by the low signal-to-noise ratio (SNR) especially in the presence of severe iron. This study aims to improve liver R2* mapping at low SNRs by averaging decay curves before the process of curve-fitting.

Iron deposits in the knee joints of a thalassemic patient [PDF]

, 2012
The overall prognosis for patients with β-thalassemia has improved considerably during the past decades mainly due to regular blood transfusions, improvements in chelation therapy, and enhanced surveillance with imaging studies examining iron overload ...

An in vivo imaging study of fascia thickness and muscle volume in the lower limb of healthy adult humans

Computer Methods in Biomechanics and Biomedical Engineering: Imaging & Visualization
Fascia is a connective tissue that influences movement and may play roles in muscle force transmission, pain sensation, and lymphatic function. To date, 3D imaging of fascia using MRI has not been achieved due to short T2* times of collagen-rich fascia ...

Attenuation correction for brain PET imaging using deep neural network based on dixon and ZTE MR images

, 2018
Positron Emission Tomography (PET) is a functional imaging modality widely used in neuroscience studies. To obtain meaningful quantitative results from PET images, attenuation correction is necessary during image reconstruction. For PET/MR hybrid systems,

Abbreviated quantitative UTE imaging in anterior cruciate ligament reconstruction

BMC Musculoskeletal Disorders, 2019
Background Existing ultrashort echo time magnetic resonance imaging (UTE MRI) methods require prohibitively long acquisition times (~ 20–40 min) to quantitatively assess the clinically relevant fast decay T2* component in ligaments and tendons.
