Ultrashort Echo Time Magnetic Resonance Imaging of the Lung Using a High-Relaxivity T Blood-Pool Contrast Agent

Molecular Imaging, 2014
The lung remains one of the most challenging organs to image using magnetic resonance imaging (MRI) due to intrinsic rapid signal decay. However, unlike conventional modalities such as computed tomography, MRI does not involve radiation and can provide ...

Estimation of trabecular bone parameters in children from multisequence MRI using texture-based regression [PDF]

, 2016
PURPOSE: This paper presents a statistical approach for the prediction of trabecular bone parameters from low-resolution multisequence magnetic resonance imaging (MRI) in children, thus addressing the limitations of high-resolution modalities such as HR ...

Making RF coils MR‐invisible by additive manufacturing using magnetically filled polymer

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 1279-1288, February 2026.
Abstract Purpose Short‐T2 MRI is sensitive not only to targeted tissues but also to signals from materials in RF coils, which can lead to image background artifacts. Current solutions to this problem either compromise imaging performance or impose restrictions on coil design.

CKD Stages, Bone Metabolism Markers, and Cortical Porosity Index: Associations and Mediation Effects Analysis

Frontiers in Endocrinology, 2021
Chronic kidney disease (CKD) has a significant negative impact on bone health. However, the mechanisms of cortical bone deterioration and cortical porosity enlargement caused by CKD have not been fully described.

Fast pseudo-CT synthesis from MRI T1-weighted images using a patch-based approach [PDF]

, 2015
MRI-based bone segmentation is a challenging task because bone tissue and air both present low signal intensity on MR images, making it difficult to accurately delimit the bone boundaries.

Impact of Surgical Diaphragmatic Repair on Central Airway Shape in Neonatal Congenital Diaphragmatic Hernia

Pediatric Pulmonology, Volume 61, Issue 2, February 2026.
ABSTRACT Rationale Neonates with congenital diaphragmatic hernia (CDH) frequently experience central airway abnormalities, including tracheobronchomalacia, which persist post‐surgical repair. However, these complications often remain underdiagnosed due to reliance on symptomatic evaluation and limited use of bronchoscopy.

Ultrashort-Echo-Time MRI of the Disco-Vertebral Junction: Modulation of Image Contrast via Echo Subtraction and Echo Times

Sensors
Introduction: The disco-vertebral junction (DVJ) of the lumbar spine contains thin structures with short T2 values, including the cartilaginous endplate (CEP) sandwiched between the bony vertebral endplate (VEP) and the nucleus pulposus (NP).

Current Uses for Medical Imaging With Orthopaedic Implant Technology

Journal of Orthopaedic Research, Volume 44, Issue 1, January 2026.
ABSTRACT Musculoskeletal applications have been at the forefront of medical imaging since the first‐ever x‐ray was taken of a hand. Radiography remains routine in orthopaedics for surgical planning and diagnosing implant complications. Fluoroscopy is used to guide intra‐operative implant placement and to assess kinematics of different implants ...
