Journal of Computer Assisted Tomography, 1994
The purpose of this study was to demonstrate that gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA) could be used as a contrast medium in CT as an alternative to iodine-based compounds.Solutions of different concentrations of Gd-DTPA and iopromide were scanned in a tissue equivalent phantom and it was shown that Gd-DTPA caused 2.5 times the ...

Tolerance data of Gd-DTPA: a review
European Journal of Radiology, 1991Gd-DTPA is the first paramagnetic contrast agent approved for clinical use in cranial and spinal MRI in the F.R.G., U.S.A., Japan and several other countries. After submission 13,439 patients were enrolled in standardized protocolled clinical trials. The observed adverse drug reactions (ADRs) after i.v.

Elimination of Gd-DTPA by means of hemodialysis
European Journal of Radiology, 1990After intravenous administration of Gd-DTPA (0.1 mmol/kg) hemodialysis was performed five times within 6 days in a patient with endstage renal failure. During the fifth hemodialysis a blood sample of 5 ml was withdrawn and Gd-concentration was measured in plasma at 342.247 nm using the method of Inductively Coupled Plasma Atomic Emission Spectrometry ...

Patients with a case history of severe side-effects from iodine-containing contrast media present problems in later radiological examination. We report here on an alternative, the first extravascular use of Gd-DTPA in an X-ray urethrography. By using the standard processing algorithm of our digital radiographic equipment and 60 ml ...

NMRD Assessment of Gd-DTPA-bis(methoxyethylamide), (Gd-DTPA-BMEA), a Nonionic MRI Agent
Investigative Radiology, 1999Gd-DTPA-BMEA, a nonionic bis(methoxyethylamide) derivative of Gd-DTPA, is the active ingredient of OptiMARK, now awaiting FDA approval. In this study, we compare the relaxivities of Gd-DTPA-BMEA (OptiMARK) with those of the commercially available DTPA-based agents Gd-DTPA2- (Magnevist) and Gd-DTPA-BMA (Omniscan) at different field strengths (1/T1 ...

A unified kinetic theory describing the dynamic properties of magnetic resonance imaging (MRI) contrast agents with a size ranging between that of Gd-DTPA and albumin-(Gd-DTPA)30 was developed and tested in disease models of cancer and myocardial reperfusion injury.

Gd-DTPA Enhancement of CSF in Meningeal Carcinomatosis
Journal of Computer Assisted Tomography, 1993We report four cases of CSF enhancement secondary to meningeal carcinomatosis observed during MRI. Only one case has been reported previously.Four patients ranging from 4 to 20 years of age, and all having primary or secondary CNS neoplasms, were examined by cranial and/or spinal MRI before and after Gd-DTPA administration.

Meningeal Gd-DTPA Enhancement in Patients with Malignancies
Journal of Computer Assisted Tomography, 1990Nineteen patients with malignant diseases and pathologically enhancing meninges were studied by pre- and postcontrast (Gd-diethylene-triamine pentaacetic acid) magnetic resonance (MR) scans. Two patterns of enhancement were recognized: the dural (14 patients) and the leptomeningeal (mainly pial) (5 patients).

Albumin-(gadolinium-diethylenetriaminepentaacetic acid), albumin-(Gd-DTPA), a macromolecular MR contrast agent designed for intravascular distribution, was compared with gadolinium-diethylenetriaminepentaacetic acid (Gd-DTPA), an extracellular fluid agent, for imaging characteristics in normal rats at 2.0 T.
