Unintentional direct intraventricular injection of gadolinium with fatal outcome: report of a case

Radiology Case Reports, 2021
Gadolinium diethylenetriamine penta-acetic acid (Gd-DTPA) is the main contrast agent used in MRI, known for its good tolerance and rare toxicity. Even intrathecal injection of limited doses of Gadolinium can be performed in some indications.

Impact of Recanalization on Liver Hypertrophy after Portal Vein Embolization and the Role of Re‐Embolization

Annals of Gastroenterological Surgery, EarlyView.
This retrospective study of 249 patients undergoing hepatectomy after right portal vein embolization (PVE) demonstrated that major recanalization–defined as recanalization more than one segment within the embolized liver–was associated with impaired regeneration of the future liver remnant (FLR).

Gadolinium-DTPA-enhanced Magnetic Resonance Imaging in Optic Neuropathies

, 1990
Magnetic resonance imaging (MRI), after intravenous administration of the paramagnetic agent gadolinium-diethylenetriaminepentaacetic acid (GdDTPA), showed enhancement of the optic nerve in 7 of 13 patients with acute optic neuritis.

Recent Advances in Functional Liver Volumetry: Emphasis on 99mTc‐GSA SPECT/CT Fusion Imaging

Annals of Gastroenterological Surgery, EarlyView.
Functional liver volumetry enables more accurate assessment of the future liver remnant by integrating anatomical and functional information, improving risk stratification before major hepatectomy. Among available techniques, 99mTc‐GSA SPECT/CT fusion imaging enables precise regional functional assessment and more reliable prediction of post ...

Gadolinium DTPA-monoamide complexes incorporated into mixed micelles as possible MRI contrast agents

, 2004
Four monoamide derivatives of Gd-DTPA with alkyl chains consisting of 12, 14, 16, or 18 carbon atoms were synthesized. The gadolinium(III) complexes with chain lengths of 14, 16 or 18 carbon atoms were efficiently incorporated into mixed micelles whereas

Hydrated clearance of gadolinium-DTPA as a measurement of glomerular filtration rate

, 1992
Hydrated clearance of gadolinium-DTPA as a measurement of glomerular filtration rate. Technetium (99mTc)-diethylene triamine pentaacetic acid (DTPA) hydrated clearance studies are accurate for determining GFR but require special facilities for handling ...

In vitro study of relationship between signal intensity and gadolinium-DTPA concentration at high magnetic field strength [PDF]

, 2001
Although gadolinium-diethylene triamine pentaacetic acid (Gd-DTPA) has been used as a contrast material in MRI, it is known that the contrast enhancement effect is not uniform for high concentrations of Gd-DTPA.

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 ...

Cyclen Tetra‐Amide Ligands as a Privileged Class of Ligands for Studying Second‐Sphere Coordination Environments

Chemistry – A European Journal, EarlyView.
Cyclen tetra‐amide derivatives provide a privileged ligand platform for controlling second‐coordination sphere structure. Hydrogen‐bond networks in the second‐coordination sphere are leveraged to stabilize a EuII‐containing cyclen tetra‐amide derivative in physiologically relevant conditions by limiting the access of O2, establishing a design‐principle
