Mn-Based MRI Contrast Agents: An Overview

Molecules, 2023
MRI contrast agents are required in the clinic to detect some pathologies, such as cancers. Nevertheless, at the moment, only small extracellular and non-specific gadolinium complexes are available for clinicians.

GADOLINIUM-BASED AND IODINATED CONTRAST AGENTS IN BREAST IMAGING: CHALLENGES AND NEW TRENDS [PDF]

, 2022
Purely morphological imaging modalities such as digital mammography and breast ultrasound still represent the backbone of breast imaging. However, a sizable diagnostic gain can be granted by functional information and improved tissue characterization ...

The safety of magnetic resonance imaging contrast agents

Frontiers in Toxicology
Gadolinium-based contrast agents are increasingly used in clinical practice. While these pharmaceuticals are verified causal agents in nephrogenic systemic fibrosis, there is a growing body of literature supporting their role as causal agents in symptoms

Gadolinium-Induced Acute Graft Pancreatitis in a Simultaneous Pancreas-Kidney Transplant Recipient

Case Reports in Nephrology, 2022
Gadolinium-induced acute pancreatitis is a rare phenomenon associated with the administration of gadolinium-based contrast agents. Only five cases of gadolinium-induced acute pancreatitis have been reported worldwide in patients with native pancreas and ...

Gadolinium as an alternative contrast medium in endovascular embolization of a dural arteriovenous fistula patient with severe iodine allergy

Interdisciplinary Neurosurgery
Gadolinium-based contrast agents can be alternative for patients with contraindications to iodinated contrast media. However, intra-arterial gadolinium-based contrast agent administration for angiography presents technical challenges due to dosage ...

How the Chemical Properties of GBCAs Influence Their Safety Profiles In Vivo

Molecules, 2021
The extracellular class of gadolinium-based contrast agents (GBCAs) is an essential tool for clinical diagnosis and disease management. In order to better understand the issues associated with GBCA administration and gadolinium retention and deposition ...

Synthesis, characterization and comparative study of aminophosphonate chelates of gadolinium(III) ions as magnetic resonance imaging contrast agents

, 1994
Gadolinium(III) complexes of aminophosphonates, including a novel ligand L4H8, have been investigated as potential contrast agents for NMR imaging. Water 1H relaxivities at 10 and 200 MHz were determined and luminescence measurements, on TbIII complexes,
