Safety of gadolinium‐DTPA: Extended clinical experience
Magnetic Resonance in Medicine, 1991AbstractThis review reports data on the general and renal tolerance of the paramagnetic contrast agent Gd‐DTPA after intravenous administration. Gd‐DTPA was administered usually at a dose level of 0.1‐0.2 mmol/kg body wt (range: 0.005‐0.25 mmol/kg body wt) in cranial, spinal and body MR indications.

Brain tumors: MR imaging with gadolinium-DTPA.
Radiology, 1985Magnetic resonance (MR) imaging was performed on 40 patients with intracranial tumors, before and after intravenous administration of gadolinium-DTPA (Gd-DTPA). Precontrast studies included a comprehensive protocol of spin-echo sequences. Tumors were visualized on precontrast images either directly or indirectly by anatomic distortion caused by the ...

MR Imaging of the Breast Using Gadolinium-DTPA
Journal of Computer Assisted Tomography, 1986In a preliminary study 20 patients underwent breast examinations by magnetic resonance (MR) imaging without and with Gd-DTPA as contrast medium. All carcinomas enhanced, whereas dysplastic tissue enhanced slightly or not at all. Significant additional diagnostic information was available on the Gd-DTPA examinations in at least four of 20 cases compared

Comparative Pharmacokinetics of Gadolinium DTPA and Gadolinium Chloride
Investigative Radiology, 1988An 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 ...

Magnetic resonance epidurography with gadolinium-DTPA
European Radiology, 1998The 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.

Renal Tolerance of Gadolinium-DOTA and Gadolinium-DTPA in Rats
Investigative Radiology, 1994Although 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 ...

Detailed Toxicity Studies of Liposomal Gadolinium-DTPA
Investigative Radiology, 1991Acute, 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 Enhancement of Lung Radiation Fibrosis
Journal of Computer Assisted Tomography, 1989Gadolinium-diethylenetriamine pentaacetic acid (DTPA) enhancement of radiation-induced apical pulmonary fibrosis was observed in two patients previously treated for breast cancer. In one case the fibrosis was biopsied twice, with no change in its CT appearance over 3 years.
