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 ...

Using Manganese‐Enhanced DCE‐MRI to Assess Blood‐Cerebrospinal Fluid Barrier Transport

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose We developed a dynamic, heavily T2‐weighted (hT2w) FLAIR protocol to resolve acute Mn2+ transport kinetics, as a proxy for Ca2+, across the choroid plexus (ChP)—cerebrospinal fluid (CSF) interface, in vivo. By quantifying intercompartmental Mn2+ dynamics, and comparing these with Gd‐DOTA, we sought to characterize blood‐CSF‐barrier ...

Dynamic SPECT Assessment of Hepatic Function in Patients With Liver Disease: A Systematic Review and Meta‐Analysis

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Introduction Dynamic Single Photon Emission Computed Tomography (dynSPECT) is an advanced functional imaging modality that enables estimation of temporal changes in radiopharmaceutical distribution and physiological function. While dynSPECT has been employed in several clinical applications, it has not been widely applied to liver imaging ...

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.

OATP1A2 mRNA downregulation in canine hepatocellular carcinoma

Veterinary Record Open, Volume 13, Issue 2, December 2026.
Abstract Background On gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd‐EOB‐DTPA) magnetic resonance imaging, canine hepatocellular carcinoma (HCC) and hepatocellular adenoma (HCA) typically exhibit low and high signal intensities in the hepatobiliary phase, respectively.

Evaluation of Phantom Doping Materials in Quantitative Susceptibility Mapping

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1545-1556, October 2026.
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.
