Aim
of this pilot study of 7T MRA was to investigate the diagnostic capability of
non-enhanced 7T MRA and the feasibility of contrast-enhanced ultrahighfield
MRA. 8 healthy subjects were examined on a 7T whole-body MR system utilizing
a custom-built 8-channel RF transmit/receive body coil. Qualitative and
quantitative analysis results demonstrate the diagnostic superiority of
TOF-MRA among the non-enhanced sequences as well as its diagnostic capability
towards contrast-enhanced MRA. In Conclusion, this first pilot study of
dedicated 7TMRA shows the feasibility of contrast-enhanced MRA, as well as
the diagnostic ability of TOF MRA e.g. in case of renal insufficiency.
