Coil Sketching for Fast and Efficient 4D Lung MRI Reconstruction

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2241-2253, April 2026.
ABSTRACT Purpose To develop and evaluate a memory‐efficient and accelerated reconstruction framework for respiratory‐resolved 4D lung MRI using coil sketching and Toeplitz approximation, enabling high‐quality motion‐compensated low‐rank (MoCo‐LR) reconstructions on clinically accessible GPU hardware.

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 ...

Ultrashort time-to-echo MRI of the cartilagenous endplate and relationship to degenerative disc disease and schmorl's nodes [PDF]

, 2011
Session - The Short of ItINTRODUCTION: The vertebral endplate is composed of an inner bony and outer cartilaginous endplates (CEP). The CEP supplies the intervertebral disc (IVD) with nutrients and metabolites, and is instrumental for metabolism ...

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.

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).

Outlook on zero/ultrashort echo time techniques in functional MRI

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 714-723, February 2026.
Abstract Since its introduction more than 30 years ago, the blood oxygenation level dependent (BOLD) contrast remains the most widely used method for functional MRI (fMRI) in humans and animal models. The BOLD contrast is typically acquired with echo planar imaging (EPI) to obtain sensitization of the signal during the echo time (TE) to dynamic changes
