The
detection of a link between the application of Gd contrast agents highlights
the need for dedicated application protocols. The purpose of the study was to
evaluate the efficacy of single dose gadobutrol compared to a substantially
higher dose gadoterate meglumine in a tumor model at 1.5T and 3.0T. All
animals were implanted Glioma cells using an implanted plastic brain cannula.
After 7 days brain MR exams were performed whether with gadobutrol or
gadoterate meglumine with a 24h interval. After the second MRI brains
harvested for histopathologic assessment. Data were evaluated regarding SNR,
CNR and lesion enhancement (LE).
