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.

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 subjects aged 40–61 years. The study included a sagittal T1-weighted SE sequence before and after i.v. injection of 0.1 mmol

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,

The effect of intravenous gadolinium-DTPA on diffusion-weighted imaging

Neuroradiology, 2006
Diffusion-weighted imaging (DWI) is usually performed before injection of intravenous paramagnetic contrast medium. Occasionally, it may be necessary to perform or to repeat DWI after such administration. Our purpose was to evaluate the effect of intravenous gadodiamide (Gd [DTPA-BMA]) on DWI.DWI was performed on 88 brain lesions immediately before ...

Echoplanar diffusion-weighted MRI with intravenous gadolinium-DTPA

Neuroradiology, 2003
It is occasionally necessary to repeat diffusion weighted imaging (DWI) after giving intravenous contrast medium (CM). However, the effects of CM on DWI and apparent diffusion coefficients (ADC) have not been fully examined. The aim of this prospective study was to investigate whether there are any diagnostically significant differences between echo ...

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).

MRI of spondylodiscities: contribution of gadolinium-DTPA and fat suppression sequence

European Radiology, 1993
Twenty-six patients with a clinical diagnosis of spondylodiscitis were examined with non-contrast and contrast-enhanced MRI in order to define the contribution of gadolinium-DTPA (Gd-DTPA) and different pulse sequences, including a fat suppression sequence (SPIR).

Comparison of the biodistribution of manganese-54 DTPA and gadolinium-153 DTPA in dogs.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1987
The biodistribution of [54Mn]DTPA and [153Gd]DTPA dimeglumine were investigated and compared following i.v. administration to fasting anesthetized dogs. Unlike most previously reported metal ion-DTPA complexes, [54Mn]DTPA showed high uptakes in several organs including the liver, bile, pancreas, bowel, and kidney.
