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.

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 ...

Impact of pre‐examination video education in Gd‐EOB‐DTPA‐enhanced liver MRI: A comparative study

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 34-41, March 2025.
This study evaluates the effects of pre‐examination video education on patient anxiety, satisfaction and image quality in Gd‐EOB‐DTPA‐enhanced liver MRI. We found that video education significantly reduced anxiety, increased patient satisfaction and improved image quality compared to standard pre‐MRI guidance, highlighting the potential of video ...

Evaluation of Phantom Doping Materials in Quantitative Susceptibility Mapping

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To measure magnetic susceptibility (χ) with Quantitative Susceptibility Mapping (QSM) and evaluate its repeatability using four phantom doping materials relevant to QSM applications. Methods A cylindrical phantom was constructed containing vials of agarose gel doped with two paramagnetic materials (ferritin, USPIO) and two diamagnetic ...

Contrast Agents for Enhanced Bioimaging: A Comprehensive Review

ChemBioChem, Volume 27, Issue 13, 14 July 2026.
Contrast agents, especially those that are nanoparticle‐based, are revolutionizing bioimaging by enabling highly sensitive, specific, and early‐stage diagnosis of diseases like cancer, using clinical imaging modalities such as CT, MRI, PET, and SPECT.

Facial Nerve Enhancement on Gadolinium-DTPA in a Case with Neurosarcoidosis.

Internal Medicine, 1997
In a case of neurosarcoidosis with bilateral facial nerve palsy and hydrocephalus, contrast-enhanced magnetic resonance imaging (MRI) study and angiotensin converting enzyme (ACE) activities in cerebrospinal fluid (CSF) were valuable for the diagnosis and the follow up. Facial nerve lesions were demonstrated on gadolinium-DTPA enhanced MRI.

Curcumin Attenuates Aroclor 1254‐Induced Oxidative, Genotoxic, and Apoptotic Alterations in HepG2 Cells

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 7, July 2026.
In HepG2 cells, Aroclor 1254 induced oxidative stress, DNA damage, apoptosis, and mutagenicity; co‐treatment with curcumin restored antioxidant defenses (GSH/thiols; SOD, CAT, GPx, GR, TrxR), reduced ROS and comet/8‐OHdG readouts, and attenuated caspase activation, demonstrating curcumin's hepatoprotective and genoprotective modulation of PCB toxicity.
