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.

Gadolinium-DTPA-enhanced MRI of intraocular tumors

Magnetic Resonance Imaging, 1990
The value of gadolinium-enhanced MRI in 30 patients with intraocular lesions has been evaluated. Seventeen patients had a uveal melanoma, two a ciliary body melanoma, three had uveal metastases, one lymphoma, four had senile macula degenerations, and three uveal nevi.

Childhood chondrosarcoma: MR imaging with Gadolinium-DTPA

Magnetic Resonance Imaging, 1990
The radiologic, CT, MR, and histological features of a case of chondrosarcoma of the femur presenting in childhood are reported. This case emphasizes the use of correlative imaging in establishing the diagnosis as well as the value of MR supplemented by Gadolinium-DTPA enhancement in disclosing abundant necrosis within the tumor.

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 ...

Gadolinium-DTPA in Spinal Disease

Radiologic Clinics of North America, 1988
The use of paramagnetic contrast agents, in particular, gadolinium-DTPA, holds great promise for the MR evaluation of the spine. However, because of the lack of a previous model for intravenous contrast enhancement in the spine and because of some peculiarities of enhancement of spinal lesions, close attention must be paid to the appropriate uses of ...

Il Gadolinium-DTPA in Risonanza Magnetica

Rivista di Neuroradiologia, 1988
Gli autori presentano una casistica di 103 pazienti studiati alla RMN con Gadolinio-DTPA. In 88 casi lo studio era indicato per lesione espansiva endocranica e in 15 spinale. Nel caso dei tumori endocranici il Gadolinio-DTPA ha permesso una migliore definizione della massa neoplastica ed una più chiara dimostrazione dei suoi rapporti con l'edema ...

Spinal cord tumors: gadolinium-DTPA-enhanced MR imaging

Neuroradiology, 1991
To assess the utility of gadolinium-DTPA (Gd) and of MR imaging in the evaluation of spinal cord tumors, ten consecutive patients were prospectively evaluated. T1-proton density-, and T2-weighted images were obtained in sagittal or axial planes. T1-weighted images were obtained before and after intravenous administration.

Gadolinium-DTPA enhanced MR imaging of intramuscular abscesses

Magnetic Resonance Imaging, 1987
Sterile, chemical and bacterial abscesses were induced in the paraspinal muscles of 16 rats before obtaining magnetic resonance (MR) images using a 0.35-T resistive system. Abscess intensity, T1 and T2 values were recorded before and after the intravenous administration of Gd-DTPA (0.2 mmol/kg).

Gadolinium-DTPA-Enhanced MRI in Facial Palsy

1994
We evaluated the specificity of facial nerve enhancement on magnetic resonance imaging (MRI) using contrast agent gadolinium-DTPA (Gd-DTPA) for the diagnosis of facial nerve lesions.

Delayed Magnetic Resonance Hepatic Imaging with Gadolinium-DTPA

Investigative Radiology, 1988
Magnetic resonance imaging of the liver was performed on 11 rabbits (3-5 kg) before and at 4, 5 and 6 hours after the intravenous administration of 0.3 mM/kg Gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA) to determine if hepatocytes exhibit delayed excretion of Gd-DTPA, similar to the delayed hepatic excretion of iodinated contrast agents ...
