Gadobutrol fdating, -- At least one gadolinium-based contrast agent GBCA appears to be steering clear of problems related to gadolinium retention. Researchers in South Korea found no evidence of gadolinium retention following multiple administrations of the agent gadoterate meglumine, according to a study published online in PLOS One. The study of patients found no significant difference in dentate nucleus-to-pons and globus pallidus-to-thalamus signal-intensity ratios between unenhanced T1-weighted images and subsequent MRI scans that used gadoterate meglumine Dotarem, Guerbet as a contrast material.
Ji Ye Lee and Dr. Over the past few years, several studies have revealed that minute traces of gadolinium can remain in certain regions of brain long after GBCA injection, manifesting as greater T1 signal intensity during unenhanced MRI scans.
In comparisons of various GBCA types, researchers have found that macrocyclic agents have reduced signal intensity -- or none at all -- compared to linear agents.
For example, a March study by Radbruch et al found no evidence of increased signal intensity in the dentate nucleus of pediatric patients who had received Gadobutrol fdating meglumine, a macrocyclic GBCA. The same researchers came to a similar conclusion in a December study that evaluated signal intensity from gadoterate meglumine and another macrocyclic GBCA, gadobutrol Gadavist, Bayer HealthCare. While other clinical Gadobutrol fdating have reported a change in T1 signal intensity for the three commercially available macrocyclic GBCAs -- gadoteridol ProHance, Bracco Diagnosticsgadobutrol, and gadoterate meglumine -- Lee, Park, and colleagues noted that the increases were not statistically significant.
Gadoterate meglumine has been used as the primary GBCA at their institution sinceaccording to Gadobutrol fdating researchers.
To explore any potential adverse effects from the agent, they investigated various clinical situations, including patients who received more 20 administrations, as well as the time interval between MRI scans and whether patients received chemotherapy or radiation therapy. The group "Gadobutrol fdating" records dating from March through July and found a total of patients who met the study's inclusion criteria.
The women and men had a mean age Gadobutrol fdating All scans were performed on a 1.
Patients were given a standardized single dose of 13 mL of gadoterate meglumine. Regions of interest ROIs targeted the right dentate nucleus, central pons, right globus pallidus, and right thalamus. Two readers then compared the signal intensities of the four brain regions for the first unenhanced MRI scan and the last GBCA-enhanced scan.
To determine any differences, ratios were calculated for the dentate nucleus and pons and for Gadobutrol fdating globus pallidus and thalamus.
Gadobutrol fdating abnormal renal function showed a significant increase in the mean dentate nucleus-pons signal-intensity ratio difference Interestingly, the mean globus pallidus-thalamus signal-intensity ratio showed Gadobutrol fdating significant decrease from the first unenhanced MRI scan 1.
The group cited several limitations to the study, including its retrospective approach. In addition, only four brain regions were selected for sources for signal intensity. No residual gadolinium found after GBCA use.
Axial T1-weighted MR images show regions of interest in the quantification of signal intensity dashed lines for the globus pallidus, thalamus, dentate nucleus, and pons.

Also shown are the dentate nucleus and pons lower row from the first scan and after 21 administrations of macrocyclic ionic GBCA.
