Automated Coregistered Segmentation for Volumetric Analysis of Multiparametric Renal MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose This study aims to develop and evaluate a fully automated deep learning‐driven postprocessing pipeline for multiparametric renal MRI, enabling accurate kidney alignment, segmentation, and quantitative feature extraction within a single efficient workflow. Methods Our method has three main stages.

Free‐Running Three‐Dimensional Cardiac Extracellular Volume Mapping in a Single Scan With Mid‐Scan Contrast Injection

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a new method for free‐running three‐dimensional (3D) extracellular volume mapping of the heart in a single scan with mid‐scan contrast injection. Methods 3D cardiac MR imaging was performed with a single scan that acquired k‐space data continuously using an inversion recovery (IR) sequence with a spoiled gradient‐echo ...

Postexercise Lactate Clearance, T2 Relaxation, and J‐Modulation in Human Skeletal Muscle Measured With Double‐Quantum Filtered 1H MRS at 7 T

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose 1H MRS lactate measurements are potentially valuable for studying energy metabolism in working skeletal muscle, but some technical obstacles need to be overcome. Spectral filtering to isolate the lactate signal from overlapping lipid resonances shows promise.

Simultaneous Volumetric T1 and T2 Mapping With Blood‐ and Fat‐Suppression in Abdominal Aortic Aneurysms

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop and validate a protocol for simultaneous volumetric T1 and T2 mapping with blood‐ and fat‐suppression, and apply it to patients with abdominal aortic aneurysms (AAA) to assess tissue characteristics. Methods A spoiled gradient echo (SPGR) variable flip angle (VFA) acquisition was modified with preparation modules to suppress
