ABSTRACT In specific MRI applications, RF coils must operate at multiple resonance frequencies to support multinuclear imaging and spectroscopy. Designing such coils that can either resonate at or switch between multiple frequencies presents considerable technical challenges. Traditional multituned coils typically suffer from …

Cerebrovascular inflammation is a critical driver of secondary injury following traumatic brain injury (TBI), yet no noninvasive tool currently exists to map its spatial heterogeneity across the injured brain. Here, we report MoNP-SPION, a monocyte-mimetic nanoprobe that selectively targets activated cerebrovascular endothelium …

Background: The potential long-term effects of Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) infection on the brain structure have not yet been fully elucidated. Even though existing studies have reported structural changes in the post-COVID-19 period, the results remain highly inconsistent and controversial. …

Abstract Superparamagnetic iron oxide nanoparticles (SPION) are investigated as T2 contrast agents for magnetic resonance imaging (MRI) of atherosclerosis. However, their nonspecific biodistribution and low plaque‐site bioavailability limit their translational potential. To address these challenges, monocyte membrane‐cloaked polymeric nanoparticles encapsulating SPION (MoNP‐SPION) …

Motivation: While PIN diode-based RF switching is the current standard for tunable radio frequency (RF) coils in MRI, the resistive losses of PIN diodes and the interference from electrical bias circuits are well-known to degrade the signal-to-noise ratio (SNR). Goal(s): We aim …

Heart disease continues to be the leading cause of death globally, even with the development and implementation of numerous pharmacological and surgical treatments. Transplanting cardiomyocytes derived from human-induced pluripotent stem cells (hiPSC-CMs) shows potential for repairing heart damage. However, tracking and quantifying …

Abstract The objective of the current study is to develop a new method for tracking transplanted human induced pluripotent stem cells‐derived cardiomyocytes (hiPSC‐CMs) using magnetic resonance imaging (MRI). The CRISPR/dCas9 activation system is employed to overexpress ferritin heavy chain (FHC) in hiPSC‐CMs. …
