r1 and r2 Relaxivities of Dendrons Based on a OEG-DTPA Architecture: Effect of Gd3+ Placement and Dendron Functionalization

Journal of Nanotechnology, 2015
In magnetic resonance imaging, contrast agents are employed to enhance the signal intensity. However, current commercial contrast agents are hindered by a low relaxivity constant.

A Comprehensive Review of Adsorbents for Rare Earth Separation: Design, Synthesis, Adsorption Performance, and Mechanisms

Rare Metals, EarlyView.
ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

Effect of Mg and Ca on the Stability of the MRI Contrast Agent Gd–DTPA in Seawater

Frontiers in Marine Science, 2018
Gadolinium diethylenetriaminepentaacetic acid (Gd–DTPA) is widely applied as a contrast enhancer in medical MRI. As Gd–DTPA is only minimally captured in wastewater treatment plants (WTPs) or degraded by UV light and other oxidative processes ...

Acute phase reaction to gadolinium-DTPA in dialysis patients [PDF]

Nephrology Dialysis Transplantation, 2008
Several late sequelae of the administration of gadolinium (Gd)-containing MRI contrast agents have been described in patients with advanced renal failure. In an observational series, we found a remarkable frequency of peracute reactions after administration of Gd-DTPA used for cardiovascular evaluation before renal transplantation.In a 26-month ...

Multiparametric MRI to Predict Response to Irreversible Electroporation Plus Anti‐PD‐1 Immunotherapy in Pancreatic Ductal Adenocarcinoma

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2266-2276, April 2026.
ABSTRACT Purpose To investigate contrast‐enhanced T1‐weighted MRI and diffusion‐weighted magnetic resonance imaging (DWI) for early prediction of tumor response to combined irreversible electroporation (IRE) and anti‐PD‐1 immunotherapy. Methods Murine pancreatic ductal adenocarcinoma (PDAC) cells KRAS* were inoculated into the pancreas of C57BL/6 mice.
