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.

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 ...

Beyond X-Rays: Unveiling the Future of Dental Diagnosis with Dental Magnetic Resonance Imaging

Diagnostics
Diagnostic imaging is fundamental in dentistry for disease detection, treatment planning, and outcome assessment. Traditional radiographic methods, such as periapical and panoramic radiographs, along with cone beam computed tomography (CBCT), utilize ...

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.

ULTRASHORT TIME ECHO MRI SEQUENCE TO QUANTIFY VERTEBRAL BONE MORPHOLOGY IN YOUNG ADULTS

Current Directions in Biomedical Engineering
While MRI is the modality of choice for soft tissue imaging, its ability to visualize bone structures remains limited. In contrast, CT provides superior bone imaging but involves ionizing radiation, making it suboptimal for longitudinal studies in ...

Magnetic Resonace–Based Attenuation Correction for Micro–Single-Photon Emission Computed Tomography

Molecular Imaging, 2012
Attenuation correction is necessary for quantification in micro–single-photon emission computed tomography (micro-SPECT). In general, this is done based on micro–computed tomographic (micro-CT) images.
