About the gadolinium contrast link between agents (GBCAs) and nephrogenic systemic fibrosis and GBCA in brain tissue accumulation was found , it caused the people to this type of contrast agent generated considerable research interest in the biological role
About the gadolinium contrast link between agents (GBCAs) and nephrogenic systemic fibrosis and GBCA in brain tissue accumulation was found , it caused the people to this type of contrast agent generated considerable research interest in the biological role
Most previous studies have used T1 signal enhancement as a measure of potential gadolinium accumulation in brain tissue .
Recently, a study published in the journal Radiology explore the QSM in the detection of primary brain tumors in patients with continuous use of macrocyclic type GP DN and the magnetic susceptibility changes after GBCA ability for people to further clarify the GBCA provides theoretical support mechanism of action , Which paved the way for the wide application of QSM in clinical practice
Diagnosis of gadobutrol GBCA gadobutrol
This study analyzed a total of 199 MRI scans of 90 patients (mean age 51 years ± 17 years [standard deviation]; 51 men)
Gadobutrol injection frequency and GP --3 gadobutrol and DN --3 gadobutrol susceptibility related to gadobutrol injection frequency is still an independent predictor of increased susceptibility GP --3 gadobutrol -3 -3 gadobutrol There is no correlation between the number of injections and SI or susceptibility in DN

This study proves that the magnetic susceptibility of gadobutrol in patients with repeated injections of gadobutrol is positively correlated with the number of injections of gadobutrol .
