Early adolescence is a critical period of brain development. This study examined regional neurometabolite ratios, their longitudinal stability, and their heritability during early adolescence. Forty-four adolescent twins (mean age: 13.25 ye...
Heterogeneous Myocardial Adaptation to Pressure Overload Reveals a Spared, Vulnerable Segment Identified by Multiparametric Cardiac MRI [0.03%]
基于多模心脏磁共振成像的压负荷下心肌异质性适应及易损段的识别
Vitali Koch,Andreas T Ochs,Simon Martin et al.
Vitali Koch et al.
Cardiac adaptation to chronic pressure overload is traditionally viewed as a uniform concentric hypertrophy; however, growing evidence suggests that the myocardium responds in a spatially heterogeneous manner. This study aimed to systematic...
DEEP-DISORDER: Motion Correction in 3D MRI via Segment Reconstruction and Registration [0.03%]
基于分割重建和配准的三维MRI深运动矫正方法
Laurens Beljaards,Martijn Nagtegaal,Chinmay Rao et al.
Laurens Beljaards et al.
3D MR image acquisition is inherently time intensive, rendering it susceptible to patient motion during scanning. This may introduce significant blurring and artifacts, potentially necessitating reacquisition. We propose a modular framework...
Accelerating PREFUL MRI: Comparison of Registration Methods and Impact of Time Series Reduction [0.03%]
改进PREFUL MRI方法的注册技术及时间序列降维影响的研究
A Voskrebenzev,G H Pöhler,F Klimeš et al.
A Voskrebenzev et al.
The purpose of this study is to evaluate whether accelerated registration and reduced acquisition times preserve the robustness of phase-resolved functional lung (PREFUL) MRI, thereby improving clinical feasibility by facilitating integrati...

Q-MRS: Quantitative Magnetic Resonance Spectral Analysis Using Deep Learning [0.03%]
基于深度学习的定量磁共振波谱分析(Q-MRS)
Christopher J Wu,Lawrence S Kegeles,Douglas L Rothman et al.
Christopher J Wu et al.
Quantification of magnetic resonance spectroscopy (MRS) data using linear combination modeling (LCM) is challenging, partly due to the large number of spectral parameters to be estimated. Popular conventional LCM approaches often place soft...
Noninvasive Mapping of Creatine Kinase Metabolism in Human Muscle Using pH-Insensitive PCrCEST MRI at 3 and 5 T [0.03%]
利用pH不敏感的PCrCEST MRI在3T和5T下非侵入性地绘制人体肌肉中磷酸肌酸激酶代谢情况
Xinran Chen,Xi Xu,Chongxue Bie et al.
Xinran Chen et al.
Phosphocreatine (PCr) recovery after exercise reflects creatine kinase (CK) metabolism and is a key marker of muscle energetics. However, current chemical exchange saturation transfer (CEST)-based PCr imaging (PCrCEST) remains limited by pH...
Monte Carlo Assessment of Accuracy for Mean Kärger Model Water Exchange Rate Estimates From Diffusional Kurtosis Time Dependence [0.03%]
蒙特卡洛评估平均KÄRGER模型水交换速率估计的准确性及其扩散各向异性时间依赖性
Jens H Jensen,Ricardo Coronado-Leija,Els Fieremans
Jens H Jensen
Intercompartmental water exchange in brain and other biological tissue can be probed in vivo with diffusion MRI (dMRI). We assess the accuracy of a recently proposed method for estimating a mean exchange rate by performing Monte Carlo simul...
Cross-Site Generalization of CNN-Based [Formula: see text] Mapping in UHF MRI [0.03%]
基于CNN的UHF MRI中的跨站点[公式见正文中图]-图绘制通用性研究
Kimon Hadjikiriakos,Felix Krüger,Felix Frederik Zimmermann et al.
Kimon Hadjikiriakos et al.
Convolutional neural networks (CNNs) can rapidly predict channel-wise B 1 + $$ {B}_1^{+} $$ maps from 7T localizer images, reducing acquisition time to seconds. This paper investigates if a CNN trained on one site's data can generalize ...
Cerebral Hemodynamic Changes During Cardiac Surgery: A Feasibility MR Study in Piglets [0.03%]
猪let中进行心脏手术期间脑血流动力学变化的可行性磁共振研究
Dominik T Schulte,Ruth O&#x;Gorman Tuura,Henning Richter et al.
Dominik T Schulte et al.
Congenital heart disease often requires early surgical intervention. Cardiopulmonary bypass (CPB) is a standard procedure, but infants undergoing CPB show an increased risk of postoperative white matter injury. These injuries are associated...
Exploring the Role of Vascular Factors and Tissue Properties in Pulsatile Brain Deformation [0.03%]
