Gadolinium (Gd), a rare-earth lanthanides metal, is widely utilized for various industrial and medical purposes, particularly in brain magnetic resonance imaging. However, its potential effects on the impairment of the central nervous system remain uncertain, especially with regard to the mitochondria, the potential primary target in metal-induced neural injury. This study investigates the effe...
Recently, several studies reported increased signal intensity (SI) in the dentate nucleus (DN) after repeated application of gadolinium-based contrast agents (GBCAs), suggesting a deposition of gadolinium in this location. Patients with relapsing-remitting multiple sclerosis (RRMS) frequently show increased permeability of the blood-brain barrier as part of the inflammatory process in the brain...
Nephrogenic Systemic Fibrosis is a rare condition appearing only in patients with severe renal impairment or failure and presents with dermal lesions and involvement of internal organs. Although many cases are mild, an estimated 5% have a progressive debilitating course. To date, there is no known effective treatment thus stressing the necessity of ample prevention measures. An association with...
CONTEXT Unlike other islet-cell tumors, insulinomas are usually benign. Most insulinomas have a high signal intensity on T2-weighted images and a low signal intensity on T1-weighted images, and are hyperintense on immediate post-gadolinium images. However, in rare cases, insulinomas may be hypointense on T2-weighted images and on immediate post-gadolinium images, mimicking a ductal adenocarcino...
In current practice, gadolinium-based contrast agents have been considered safe when used at clinically recommended doses in patients without severe renal insufficiency. The causal relationship between gadolinium-based contrast agents and nephrogenic systemic fibrosis in patients with renal insufficiency resulted in new policies regarding the administration of these agents. After an effective s...
D epartm ent of Radiology. University of California, San Francisco, California 94143, USA Z. Naturforsch. 41b, 1170—1177 (1986); received February 20, 1986 Bovine Serum Albumin, Gadolinium Complexes, Contrast Agents for NMR Imaging, Nitroxyls Bovine Serum Albumin (BSA) was spin labeled using the active esters 3 and 5 containing a nitroxyl radical to give the spin labeled BSA derivatives 4 and 6...
Gadolinium-based contrast agents (primarily those with linear chelates) are associated with a dose-dependent signal hyperintensity in the dentate nucleus and the globus pallidus on unenhanced T1-weighted MRI following administration to selected patients with normal renal function. The accumulation of gadolinium has also been reported in the skin, heart, liver, lung, and kidney of patients with ...
There is growing recognition of the association between the use of gadolinium-containing radiocontrast agents for magnetic resonance imaging and the serious dermal and systemic disease nephrogenic fibrosing dermopathy/nephrogenic systemic fibrosis (NFD/NSF). The pathogenesis of this entity remains unclear; however, our recent observations suggest a likely mechanism for the initial dermal manife...
UNLABELLED Background. Encapsulating peritoneal sclerosis (EPS) is a severe complication of long-term peritoneal dialysis (PD) characterized by the development of an extensive fibrosis of the visceral peritoneum that may eventually lead to intestinal constriction. Its cause remains elusive. Nephrogenic systemic fibrosis (NSF), a disabling disease that can follow gadolinium-based contrast inject...
