Gadolinium-DTPA in the evaluation of intradural extramedullary spinal disease.

American Journal of Roentgenology, 1988
Gadolinium-DTPA was used in MR imaging of the spine to determine the ability of a contrast agent to increase the detection and characterization of disease in the intradural extramedullary space. Although MR imaging, especially with recent technological improvements, has been shown to be at least competitive with, and often superior to, myelography and ...

Comparative Pharmacokinetics of Gadolinium DTPA and Gadolinium Chloride

Investigative Radiology, 1988
An intravenous injection of 153Gd-labeled gadolinium-DTPA or gadolinium chloride was given to 60 rats, which were killed either 15, 40, 120, 300, 900, or 3600 seconds later. Tissue concentrations of gadolinium in the blood, liver, spleen, stomach, pancreas, renal cortex, renal medulla, lungs, heart, adrenals, gluteal muscle, fat, skin, thymus, brain ...

Renal Tolerance of Gadolinium-DOTA and Gadolinium-DTPA in Rats

Investigative Radiology, 1994
Although gadolinium chelates are mainly eliminated by the kidney, there is limited information about their effects. The renal tolerance of these compounds on renal function in an in vivo rat model are evaluated.A combination of renal ischemia and intrarenal iodinated contrast agent infusion (diatrizoate) led to a reproducible and reversible model of ...

Biodistribution and Clearance of Liposomal Gadolinium-DTPA

INVESTIGATIVE RADIOLOGY, 1990
Gadolinium-DTPA (Gd-DTPA) liposomes have been studied previously as liver contrast agents and have been shown to improve the detection of hepatic metastases in rats. We synthesized 100-nm and 50-nm liposomes that encapsulated Gd-DTPA and did biodistribution and clearance studies in rats. Parallel magnetic resonance imaging (MRI) studies were also done.

Magnetic resonance epidurography with gadolinium-DTPA

European Radiology, 1998
The aim of this study was to evaluate and describe MRI epidurography as a new imaging tool. Five volunteers and one patient were investigated with MR epidurography after injection of 20 ml Gd-DPTA solution (1:250/1 ml Gd-DPTA/250 ml normal saline). Magnetic resonance epidurography is possible.

Comparison of Gadolinium-DTPA and Polylysine-Gadolinium-DTPA-Enhanced Magnetic Resonance Imaging of Hepatocarcinoma in the Rat

Investigative Radiology, 1995
To compare the magnetic resonance (MR) imaging characteristics of gadolinium-DTPA (Gd-DTPA), a low-molecular-weight contrast agent, and polylysine-Gd-DTPA, a macromolecular contrast agent, in two types of hepatocarcinomas (HCC) in the rat.T1-weighted spin-echo images were obtained in 13 rats with chemically induced HCC and 26 rats with Novikoff HCC ...

Detailed Toxicity Studies of Liposomal Gadolinium-DTPA

Investigative Radiology, 1991
Acute, subacute, and delayed toxicity testing was assessed in mice for liposomal gadolinium-DTPA (Gd-DTPA), blank liposomes, and nonliposomal Gd-DTPA. In the subacute experiments mice were injected intravenously (IV) with 0.3 mmol/kg Gd-DTPA per day for 30 days in the form of either free Gd-DTPA, liposomal Gd-DTPA, or an equivalent amount of lipid in ...

Gadolinium — DTPA in magnetic resonance imaging of the brain

Neurosurgical Review, 1987
This report concerns a clinical trial with Gd-DTPA as an intravenous contrast medium for MRI in patients with neurological disorders. 50 patients (30 female, 20 male) were examined without and with Gd-DTPA and the results of CT scanning and MR scanning without and with Gd-DTPA were compared. All patients tolerated the contrast medium very well.
