Research progress in the design of gadolinium-based inorganic nanoparticles for magnetic resonance contrast agents

上海师范大学学报. 自然科学版, 2022
Magnetic resonance imaging(MRI) is one of the common detection methods in clinical medical imaging. The most commonly used longitudinal relaxation (T1) contrast agent in clinical diagnosis is Gadopentetate Dimeglumine(Gd-DTPA).

MR Imaging of Peripheral Nerves Using Targeted Application of Contrast Agents: An Experimental Proof-of-Concept Study

Frontiers in Medicine, 2020
Introduction: Current imaging modalities for peripheral nerves display the nerve's structure but not its function. Based on a nerve's capacity for axonal transport, it may be visualized by targeted application of a contrast agent and assessing the ...

Addition of gadolinium contrast to three-dimensional SSFP MR sequences improves the visibility of coronary artery anatomy in young children

Frontiers in Pediatrics, 2023
ObjectiveThis study aims to compare the value of a gadolinium contrast-enhanced 1.5-T three-dimensional (3D) steady-state free precession (SSFP) sequence with that of a noncontrast 3D SSFP sequence for magnetic resonance coronary angiography in a ...

Long-Term Treatment with Gadopentetic Acid or Gadodiamide Increases TRPC5 Expression and Decreases Adriamycin Nuclear Accumulation in Breast Cancer Cells

Cells, 2023
Gadopentetic acid and gadodiamide are paramagnetic gadolinium-based contrast agents (GBCAs) that are routinely used for dynamic contrast-enhanced magnetic resonance imaging (MRI) to monitor disease progression in cancer patients.

THE METHOD FOR OBTAINING A DERIVATIVE CLOSO-DECABORATE ANION WITH PENDANTE DTPA-GROUP

Тонкие химические технологии, 2019
This paper describes the method for obtaining a new derivative of the closo-decaborate anion with diethylenetriaminepentaacetic acid (DTPA) as a pendant group attached to the boron cluster through an alkoxyl spacer chain. This derivative is formed by the

Effect of delayed acquisition times on Gadolinium-enhanced MRI of the presumably normal canine brain [PDF]

, 2011
A delay in imaging following intravenous contrast medium administration has been recommended to reduce misdiagnoses. However, the normal variation of contrast enhancement in dogs following a delay has not been characterized.
