PURPOSE To optimize direct magnetic resonance (MR) arthrography by determining the effect of dilution of gadolinium in iodinated contrast, saline, or albumin on T1-weighted, T2-weighted, and gradient-recalled echo (GRE) images, and the effect of scanner field strength. MATERIALS AND METHODS Gadopentetate dimeglumine was diluted into normal saline, albumin, or iodinated contrast (0.625 mmol/li...

Background Cardiac magnetic resonance (CMR) late gadolinium enhancement (LGE) and early gadolinium enhancement (EGE) are powerful diagnostic tools for acute cardiomyopathies. LGE is associated with impaired prognosis in ischemic and in chronic non-ischemic cardiomyopathy (NICM), but the impact of gadolinium enhanced CMR on prognosis in recent onset NICM is less well established. We performed a ...

Gadolinium can be used to perform diskography in patients with a documented allergy to iodinated contrast material. MR images can be obtained in multiple planes with excellent delineation of disk architecture. Dilute gadolinium leaves the disk space within a few days of injection.

PURPOSE Although glaucoma treatments alter aqueous humor (AH) dynamics to lower intraocular pressure, the regulatory mechanisms of AH circulation and their contributions to the pathogenesis of ocular hypertension and glaucoma remain unclear. We hypothesized that gadolinium-enhanced magnetic resonance imaging (Gd-MRI) can visualize and assess AH dynamics upon sustained intraocular pressure eleva...

We evaluated the incidence of contrast-induced nephropathy (CIN) in patients exposed to gadolinium for diagnostic or therapeutic procedures. Background: CIN with iodinated contrast agents is a leading cause of acute renal failure. Gadolinium is often used as an alternative to iodinated contrast in patients at increased risk of CIN. The safety of gadolinium in patients at increased risk of CIN h...

BACKGROUND AND PURPOSE Gadolinium-based contrast agents have been associated with lasting high T1-weighted signal intensity in the dentate nucleus and globus pallidus, with histopathologically confirmed gadolinium retention. We aimed to longitudinally investigate the relationship of multiple gadolinium-based contrast agent administrations to the Signal Intensity Index in the dentate nucleus and...

   In the present work, Gadolinium Doped ceria (GDC) based solid electrolyte was successfully synthesized through wet chemical method to operate at intermediate temperature (500–700°C) for SOFCs. DSC study revealed the formation of GDC phase at 900°C during calcination. The crystal structure of GDC was identified as cubic fluorite phase and the crystallite size was found to be around 23 nm....

Several MRI contrast agents (CAs) are used in medical diagnosis that gadolinium (Gd3+) is the most widely used as contrast agents. Unfortunately, its toxicity is due to its inefficiency. In this review, we discuss about the ability of SPIONs in MRI and application in Multiple Sclerosis diagnosis. Superparamagnetic iron oxide nanoparticles (SPIONs) such as magnetite nanoparticles are used as goo...

Nephrogenic systemic fibrosis (NSF) is a serious, sometimes fatal disease. Findings in recent years have shown that a causal association between gadolinium containing contrast media and NSF is most likely. Therefore, the regulatory authorities have issued guidelines on the use of gadolinium-containing contrast media which have reduced the number of new cases of NSF to almost zero. However, it i...

BACKGROUND AND PURPOSE Iron oxide-based contrast agents have been investigated as more specific MR imaging agents for central nervous system (CNS) inflammation. Ferumoxtran-10 is a virus-size nanoparticle, taken up by reactive cells, that allows visualization of the phagocytic components of CNS lesions. Ferumoxtran-10 was compared with standard gadolinium-enhanced MR images in this exploratory ...
