purpose of this study was to investigate the potential of an ultra-short TE
3D radial sequence, for imaging the prostate at 7T. This technique is
desirable for DCE-MRI because it would greatly reduce both the large T2*
effect of paramagnetic contrast agents at high field, and the inflow
artifacts that can bias the measurement of the arterial input function.
Furthermore the sequence gives spatially isotropic resolution and, when
combined with sparse temporal sampling methods, can provide very high
temporal resolution. This work
demonstrates the feasibility and imaging quality of this technique and
discusses its strengths and weaknesses.
