MRI-derived carotid maps may support early management of atherosclerosis
The goal of this study was to determine whether patient-specific and cohort-averaged wall thickness, wall shear stress, and vessel diameter maps can be used for creating 3D estimation models for patient-specific wall thickness in asymptomatic atherosclerotic carotid... Impact of fixation, coil, and number of excitations on diffusion tensor imaging of rat brains at 7.0 T
The authors of this study set out to compare diffusion tensor imaging (DTI) parameters in vivo and ex vivo in the brain and to explore the effects of radiofrequency coil and number of excitations on ex vivo DTI parameters. By obtaining DTI maps from rat brains and... MRI assessment of altered dynamic changes in liver haemodynamics following a meal challenge in compensated cirrhosis
The aim of this study was to use MRI for dynamically assessing postprandial changes in hepatic and collateral blood flow, liver perfusion and oxygenation in healthy participants and patients with liver disease with compensated cirrhosis. The authors were able to... Estimated intracranial volume from FreeSurfer is biased by total brain volume
Since estimated intracranial volume (eTIV) from FreeSurfer is calculated from the alignment of the input MR images to the MNI305 brain atlas, and is not segmentation-based, a concern was raised that this might lead to a bias by total brain volume. This study managed... Respiratory level tracking with visual biofeedback for consistent breath-hold level with potential application in image-guided interventions
This study aimed to present and evaluate a new respiratory level biofeedback system that helps the patient to have a consistent breath-hold level. The results showed an increased reproducibility of breath-hold expiration level in healthy volunteers, indicating a... Splenectomy for hypersplenism with or without preoperative splenic artery embolisation
Due to the fact that intraoperative blood loss is a common occurrence in splenectomy, the authors set out to compare the perioperative and clinical outcomes of splenic artery embolisation (SAE) prior to splenectomy versus splenectomy alone. On a total of 100 patients,... Dual-layer spectral computed tomography: measuring relative electron density
The goal of this study was to examine the feasibility and accuracy of a novel dual-energy CT technique in measuring the electron density. By using dual-layer CT (DLCT), the authors investigated two approaches to obtain relative electron densities. The results showed...ESR Journals Editors’ Round Table
