Comparison of 2D and 4D Flow MRI in Neonates Without General Anesthesia

Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 71-82, January 2023., 2023
Background Neonates with critical congenital heart disease require early intervention. Four‐dimensional (4D) flow may facilitate surgical planning and improve outcome, but accuracy and precision in neonates are unknown. Purpose To 1) validate two‐dimensional (2D) and 4D flow MRI in a phantom and investigate the effect of spatial and temporal resolution;

Xixin Decoction May Treat Vascular Dementia by Modulating the NPTX2/C1q/C3 Complement Pathway

Chemistry &Biodiversity, EarlyView.
To establish a VaD model, SD rats underwent unilateral common carotid artery ligation, followed by gavage treatment with Xixin decoction. Cognitive abilities of the rats were assessed through Morris water maze and new object recognition. Pathological changes were observed using electron microscopy observation, Golgi staining, and Nissl staining ...

Low‐field MRI: Clinical promise and challenges

Journal of Magnetic Resonance Imaging, Volume 57, Issue 1, Page 25-44, January 2023., 2023
Modern MRI scanners have trended toward higher field strengths to maximize signal and resolution while minimizing scan time. However, high‐field devices remain expensive to install and operate, making them scarce outside of high‐income countries and major population centers.

Novel Transthoracic Pulmonary Valve Implantation Using Self‐Expanding Salus Valve: A Prospective Study of Safety and Mid‐Term Outcomes

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter pulmonary valve replacement (TPVR) has emerged as a valuable treatment for severe pulmonary regurgitation (PR). The Salus valve (Balance Medical Technology Co. Ltd., Beijing, China) represents a novel self‐expanding valve stent designed for deployment through a transthoracic approach with a small subxiphoid incision ...
