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 ...

Gadolinium-DTPA-Enhanced MRI of the Facial Nerve

1994
Gadolinium(Gd)-DTPA-enhanced magnetic resonance images (MRI) of facial nerves in the temporal bone were evaluated to ascertain the relation between the duration of the disease and the sites of enhancement.

Comparison of Gadolinium-DTPA and Macromolecular Gadolinium-DTPA-Polylysine for Contrast-Enhanced Pulmonary Time-of-Flight Magnetic Resonance Angiography

Investigative Radiology, 1996
The authors investigated the enhancing effect of low-dose administration of the macromolecular, paramagnetic contrast medium gadolinium (Gd)-DTPA-polylysine (average molecular weight, 40,000-50,000 dalton [D]) compared with Gd-DTPA (molecular weight, 547 D) in time-of-flight magnetic resonance angiography of unilaterally damaged sheep lungs.Thirteen ...

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.

An Improved Method for the Preparation of Liposomal Gadolinium-DTPA

Investigative Radiology, 1991
We have developed an improved method for the production of liposomal gadolinium-DTPA (Gd-DTPA). The ionophore A23187 facilitates the uptake of externally added Gd into the interior aqueous space of a unilamellar lipid vesicle, where it is chelated by passively entrapped DTPA to form the Gd-DTPA chelate in situ.

The Effects of Gadolinium-DTPA and -DOTA on Neural Tissue Metabolism

Investigative Radiology, 1991
Gadolinium DTPA and DOTA are being used extensively for imaging blood-brain barrier lesions. This study was performed to determine clinically relevant blood, cerebrospinal fluid (CSF), and neural tissue concentrations of these agents, and to determine if they alter neural tissue glucose metabolism.

Gadolinium-DTPA enhanced MR imaging in tuberous sclerosis

Neuroradiology, 1990
Ten patients with clinical tuberous sclerosis were examined with CT and MR imaging, before and after IV contrast in order to determine the role of Gd-DTPA. Gd-DTPA enhancement occurred in eleven subependymal nodules which did not enhance on CT after IV contrast.

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 ...

Leiomyosarcoma of abdominal veins: Value of MRI with gadolinium DTPA

Abdominal Radiology, 1994
Primary leiomyosarcomas of the retroperitoneum are rare tumors, the vast majority of which are malignant. Prognosis is largely dependent upon adequacy of surgical resection. Magnetic resonance imaging (MRI) is ideally suited to the evaluation of these neoplasms because of multiplanar imaging capability, inherent signal intensity differences of tissues,

Gadolinium-Dtpa-Enhanced MR Imaging in Asymptomatic Knees

Acta Radiologica, 1996
Purpose: To evaluate the occurrence and extent of Gd-DTPA-enhanced synovial structures in asymptomatic knee joints of middle-aged healthy individuals. Material and Methods: MR imaging of the knee joint was performed in 10 healthy ...
