So-called
gringing artifactsh are often associated with Primovist-enhanced dynamic MR
imaging, aggravating the diagnosis for focal hepatic lesions. To analyze the cause of this phenomenon,
various scan and data acquisition parameters were tested using a newly
created simulation software on the personal PC. The simulation study revealed that square
matrices, short scanning time, slow infusion rate, and sequential view
ordering were effective measures to reduce the artifacts. These results were confirmed in the
clinical practice of Primovist-enhanced MR imaging.
