Deep Learning-Based Dynamic Segmentation of the Left Atrium in 4D Flow MRI. [PDF]

Magn Reson Med
ABSTRACT Purpose To design a deep learning pipeline for automated, time‐resolved segmentation of the left atrium (LA) from 4D flow MRI data. Methods We studied 100 individuals including 65 patients with atrial fibrillation (AF) and 35 healthy subjects (HS) resulting in 2530 4D flow MRI time‐volumes acquired in different centers and scanners.

Association Between Motor Pathway Damage and Motor Deficit in Upper and Lower Limb in People With MS. [PDF]

Ann Clin Transl Neurol
ABSTRACT Objective Corticospinal tract damage is common in people with MS, but the degree of clinical symptoms varies. We hypothesize that corticospinal tract lesions are more extensive and severe in people with MS with motor impairments in both upper and lower limbs.

Multicenter Assessment of Combined Brain and Cervical Spinal cord 3T MP2RAGE T1 Measurements for Reliable Tissue Microstructure Quantification. [PDF]

NMR Biomed
Reliability of simultaneous brain and spinal cord magnetization‐prepared two rapid acquisition gradient echoes (MP2RAGE) T1 measurements was evaluated in a multicentre context. Mean intra‐site/inter‐site/between‐participant coefficients of variation (COV) were 0.4/0.9/2.3% for the brain ROIs and 2.0/2.4/1.7% for the cSC, confirming the potential of T1 ...

A Novel MR Elastography Device for Preclinical Applications From Spheroids to Rodents: Design, Validation, and Performance Evaluation [PDF]

NMR Biomed
MR elastography (MRE) noninvasively assesses tissue biomechanics, but preclinical research suffers from diverse hardware solutions, hindering reproducibility and comparability. This study introduces a versatile preclinical MRE device for imaging rodents, ex vivo samples, and spheroids/organoids.

Skeletal Muscle Fibre Type Determines Mitochondrial and Metabolic Responses to Hypoxia and Pulmonary Inflammation in Young Adult Rats. [PDF]

J Cachexia Sarcopenia Muscle
ABSTRACT Background Chronic obstructive pulmonary disease (COPD) patients often experience skeletal muscle dysfunction that may result from a complex combination of mitochondrial dysfunction, metabolic reprogramming and fibre type transitions. Among other factors, pulmonary inflammation and hypoxia contribute to the COPD‐associated muscle defects ...

Impairments in mitochondrial dynamics and morphology in skeletal muscle of breast cancer patients after a single paclitaxel administration. [PDF]

Exp Physiol
Abstract Standard chemotherapy regimens for patients with breast cancer are based on epirubicin–cyclophosphamide (EC) and paclitaxel (TAX) administrations. While it has been shown that first EC administration impairs mitochondrial homeostasis, the isolated effects of TAX have not been studied without previous chemotherapy exposure.

Magnetoencephalographic source imaging improves localization of the epileptogenic zone in multimodal imaging evaluation. [PDF]

Epilepsia
Abstract Objective To assess the added diagnostic value of magnetoencephalographic source imaging (MSI) beyond conventional magnetic resonance imaging (MRI) and fluorodeoxyglucose–positron emission tomography (FDG‐PET) in localizing the epileptogenic zone, with stereo‐electroencephalography (SEEG) and surgical resection serving as reference standards ...
