The
ASTM-Standard F2119-07 is used to evaluate artifacts of implants. According
to the test method a phantom with CuSO4 is used. By replacing the solution by
mineral oil it is desired to avoid standing waves in images. We tested both
fluids in two sequences (SE/GRE) with 2 test devices, a Nitinol stent and an
acryl reference tube. We compared a visual, a statistically and a manual analysis.
We noticed non-significant results with one exception. Under certain
conditions the standard CuSO4 can be exchanged with mineral oil allowing
better and precise artifact analysis at higher field strengths 3 T.
